Section 1Overview

1.1 Description

The EtherAnt II™ is a flat panel directional antenna with a built-in wireless Ethernet adapter. The

equipment is 802.11b WiFi™ compliant, operates at up to 11 Mbps and features 128-bit WEP (WiredEquivalent Privacy) and the new Agere WEP-Plus. The EtherAnt II provides efficient outdoor high-speedwireless connectivity for desktop PCs, laptop computers and routers equipped with an Ethernet port.

The EtherAnt II offers the simplest, most efficient 2.4 GHz Wireless Internet access solution for anEthernet-enabled desktop PC. It will communicate with any Access Point or other wireless client that is100% WiFi™ compatible. It is ideal for use as a client station device for Wireless Internet applications.

With the wireless client adapter built right into the antenna, there are no complicated hardwareconfigurations or radio frequency (RF) cables. Because the EtherAnt II has the radio built-in, professionalantenna installation is not required. Once the EtherAnt II is connected, simply install the Client Managerfrom the CD-ROM included in the kit and configure the network settings.

Two variations of the EtherAnt II are available: the standard series EtherAnt II with an integral 18 dBi gainflat panel antenna, and the EtherAnt II –LR with the addition of an integrated bi-directional fixed amplifierto boost range and improve reception. The antenna housing is waterproof and intended to be a pole orwall-mounted outdoor installation.

For those customers that have multiple PCs on a LAN, a low-cost Cable/DSL router can be used toprovide a firewall and NAT for their PCs. Access to the internet can be provided with the reassurance ofhaving the customer's LAN behind a firewall. If a router/firewall is not desir ed, the EtherAnt II can also beplugged directly into a customer's LAN. The built-in Micro-routing feature

1 automatically routes IP packets

for up to 253 MAC addresses on the LAN, no special configuration is necessary!

The Micro-routing algorithm maintains an auto-indexed IP-to-MAC address table by inspecting eachreceived 802.3 Ethernet frame. Thereafter, the EtherAnt's local MAC address is superimposed as the

source address field within the frame prior to transmitting it on the wireless (802.11b) network.Reciprocally, whenever a wireless (802.11b) frame is received, the algorithm inspects the destination IPaddress and remaps the associated MAC address into the destination field of the Ethernet frame. Thesource address field within the frame is then replaced with the EtherAnt's local MAC address prior totransmitting it on the Ethernet network.

The EtherAnt II does not require that a PC be opened in order to install an interface card provided that thePC has an Ethernet Network Interface card (NIC). Attach the outdoor Ethernet cable included in the kit(plus any optional extension cables) to the EtherAnt II. Plug the Ethernet cable into the DC PowerInjector. Connect the built-in Ethernet cable from the DC Power Injector into your computer’s10/100Base-T port, plug in the AC adapter, and your hardware installation is complete. Because theEtherAnt II uses the PC’s existing Ethernet interface, there are no drivers to install for this device.

The Windows-based Client Manager provides configuration and diagnostic utilities that allow you to seevital information regarding the link between the antenna and the base station. Information such as signal-to-noise ratio, signal strength, and noise level all in dB, provides for efficient installation and aiming of theantenna, as well as troubleshooting link problems.

The EtherAnt II kit includes a 50 foot outdoor-rated Ethernet cable with a weatherproof connector (longercables are available as an option). By using RJ-45 in-line couplers, you can extend the cable up to 300

1. Firmware 2.01 and higher





feet to connect the EtherAnt II to your network. The WLAN device located in the antenna gets its powerfrom the DC Power Injector which puts DC power onto the Ethernet cable.

NOTE: The EtherAnt II –LR can operate only with an Ethernet cable up to a maximum length of 100feet between the DC Power Injector and the antenna. This is due to the electrical resistanceof the thin Ethernet cable which drops the DC voltage to the antenna.

Both the EtherAnt II and the EtherAnt II –LR version use a 110 VAC to 15 VDC power supply. A 110/220VAC adapter can be purchased separately as an option.

Safety Warning

This antenna/transmitter device must be fixed-mounted on outdoor permanent structures with a separation distance of at least 2 meters(6.56 feet) from all persons. Users and installers must adhere to theantenna installation instructions and transmitter operating conditions inorder to comply with the FCC’s RF exposure requirements.

Section 2Installation

2.1 Locating the EtherAnt II

The most important aspect of setting up the EtherAnt II is its location and aiming. For maximum range

(up to several miles), it must have clear, unobstructed line of site (LOS) and Fresnel Zone between it andthe base station antenna or the other wireless device it is talking to. The EtherAnt II should be installedoutdoors, but can be located in a window if necessary. However, for maximum range and the strongestsignal, the EtherAnt II must “see” the base station antenna in order to be connected. If they do not havethis clear line of sight, you will likely not get a reliable, long-range wireless connection. For indoorapplications, the range will depend on the walls and other obstacles between the EtherAnt II and the basestation. The only way to accurately determine your coverage area is to put up the EtherAnt II in the bestlocations available and run some tests (see Section 2.2, Aiming Antenna and Checking Signal Strength).

NOTE: It is strongly recommended that you configure and test the unit prior to deploying it in thefield. Set up a “mini-network” that resembles your actual configuration as close as possible.By using such a mock-up, troubleshooting potential problems will be much easier than if youalready installed the equipment in the field. Read through this entire Section 2 to understand

how to install the hardware. To configure the EtherAnt II, read Section 3.

2.2 Aiming Antenna and Checking Signal Strength

The EtherAnt II has a built-in signal strength indicator which can be monitored by the YDI Client Managersoftware to help optimize the aiming of the antenna. If you are using an ORiNOCO or YDI Access Pointin your wireless network, you can also use the Link Test capability of the AP Manager software to monitorthe signal strength of the EtherAnt II into the base unit.

Another test that can be performed involves using a laptop computer, a YDI Sapphire or Diamond WLANcard, and the Wireless Client Manager program that comes with it. Insert the WLAN card in the laptopcomputer, install the program and run it. The Advanced -> Link Test screen of the Wireless ClientManager program shows signal strength levels. Walk around the desired coverage areas with the laptopcomputer and record the signal levels. This way you can build a map of the areas that have good

coverage.

For details about how to set up, configure, and use the Wireless Client Manager program, please refer tothe User Manual of the product.

2.3 Mounting the EtherAnt II

The antenna can be mounted either vertically or horizontally polarized using the hardware included withthe unit. The label located on the back of the antenna contains an arrow indicating the antenna’s

CAUTION





polarization. Please note that both ends of the link must use the same polarization. It can be mounted toa mast or pipe as shown in Figure 2.1 or to a flat surface such as a wall as shown in Figure 2.2. Note thatmost omni antennas are vertically polarized and if the EtherAnt II is aimed at one, it must be installedvertically polarized, i.e., with the polarization arrow up and down.

When installed outdoors, it is very important that the round connector plugged on the antenna be properlywaterproofed. Ensure that a high quality all-weather resistant electrical tape and/or other water sealantmethod, such as Permagum or equivalent, is utilized. Silicon sealants are not recommended sincethey are hard to work with, do not ensure a 100% waterproofing of the connectors and are difficult toremove, if ever necessary.

The antenna itself or the mast where it is bolted to should be connected to an Earth ground. Fig. 2.1shows the possible grounding points that you can use.

Figure 2.1. – Outdoor Pole Mount Installation

Figure 2.1 shows the antenna in a typicalhorizontally polarized installation. It must becarefully aimed at the base antenna and bemounted with the same polarization. The

housing is sealed to prevent water build-up inthe antenna. The round connector must alsobe sealed after it is plugged into the antenna.Be sure to provide strain relief for the Ethernetcable as well.

If this EtherAnt II antenna is aimed at avertically polarized omni-directional or sectorbase station antenna, it must be mountedvertically polarized using the other mountingstud on the back.

Figure 2.2 – Indoor Wall Mount Installation

Figure 2.2 shows the antenna in a typicalindoors wall mount installation. For indoorapplications, the range will depend on thewalls and other obstacles between theEtherAnt II and the base station. The only wayto accurately determine your coverage area isto put up the EtherAnt II in the best locationsavailable and run some tests.

Possible Grounding Points





2.4 DC Power Injector

The Cat 5 DC Power Injector is not in a waterproof enclosure and must be protected from the weather. Itcan be permanently mounted to a surface using the double stick tape found on the back of it.

2.5 Power Supply

The EtherAnt II and EtherAnt II-LR antenna kit come with a 110 VAC to 15 VDC power supply that has astandard barrel plug [center pin positive (+) tip and outer ring negative (-)]. 110/220 VAC power suppliesare available as an option. Although normally provided with a power supply, any power source meetingthe following specifications can be used:

EtherAnt II 12-24 VDC @ 500 mA maximum cable length: 300 feet

EtherAnt II-LR 15 VDC @ 1 A maximum cable length: 100 feet

CAUTION: Operating the EtherAnt II-LR version with more than 15 VDC will damage it. Operating it withless than 15 VDC will cause improper operation.

2.6 Hardware Installation

Perform the following procedures once you have determined the optimal location for the antenna:

1. If you are going to install the antenna on a mast or pipe, use the brackets and screws to mount theflat panel antenna to a pole with a maximum diameter of up to 1 3/4 inches.

2. Ensuring that there is no DC power applied to the DC Power Injector, plug the 6-pin N-male roundconnector of the outdoor Ethernet cable provided into the rear jack of the flat panel antenna, aligningthe notch on the connector with the tab on the jack as shown on Figure 2.3. Then turn the roundlocking nut clockwise as you push in until it securely fastens onto the jack. Please verify that theround connector is properly plugged into the rear jack of the antenna prior to connecting DCpower because it is possible to push it in the wrong way if enough force is used. If DC power is

applied and the connector is not properly plugged, damage to the electronics of the unit or theconnector itself may occur which will not be covered by the factory warranty.

Figure 2.3 – Plugging the Outdoor Ethernet Cable

3. Attach the other end of the outdoor Ethernet cable provided to the Cat 5 DC Power Injector at portRJ-45 labeled “To Antenna.”





If DC Power is applied while you are attempting to insert the roundconnector into the jack, it is possible that, as you rotate the plug in aneffort to find the key, DC power pins will momentarily touch the Ethernet pins. If this happens the Ethernet circuitry on the board will blow . Also, do not apply excessive pressure when you insert the roundconnector or the pins will pop out. Any damage caused by this action will

not be covered by the factory warranty and will be a billable repair.

4. Connect the Ethernet cable labeled “To PC or Router” from the Cat 5 DC Power Injector to yourcomputer or PC. If you connect to a router, switch or hub, make sure you plug the cable into theUplink/WAN port, otherwise a cross-over cable or adapter will be needed.

5. Perform an Earth ground connection to any of the rear bolts of the antenna, the mounting brackets, orthe mast if mounted outdoors (refer to Fig. 2.1). For maximum protection, YDI also recommends theuse of its optional surge protected DC Injector available from your YDI dealer (part No. 304-800620-002). This DC Injector has an additional wire to be connected to ground as shown on Fig. 2.4.

6. Plug the Power Supply into an AC outlet and connect it to the “DC Power” jack on the Cat 5 DCPower Injector.

7. Check that the Power and Ethernet LEDs are lit. For –LR models, check that the RX / Power amplifierLED (green) is also lit.

8. Configure the EtherAnt II Client Adapter using the Client Manager software. (See Section 3 fordetailed information.)

MAC Address Selection – This allows you to determine which MAC Address the EC will use forcommunication. The Current Setting is displayed on the window box. You may choose to Keep theCurrent Setting .If Use Dynamic MAC Address is clicked, the MAC Address of the most recently received Ethernet framefrom the Ethernet port will be used. Note: this setting disables Micro-routing.If Use EC MAC Address is clicked, the internal MAC Address of the unit will be used (this is the defaultsetting). Note: this setting automatically enables Micro-routing in Infrastructure and Peer to Peer modes.If Use PC Card MAC Address is clicked, the internal MAC Address of the 802.11b PCMCIA Card will beused.

Show Disconnect Message – If clicked, this option will display a message box when the attached EChas been disconnected.

Show 128-bit Warning – If clicked, this option will display a message box warning you, when configuringthe EC, to use a 128-bit WEP Encryption key.

Show IP Address Warning – If clicked, this option will display a message box when a user tries toconfigure an EC for an IP address that is out of the subnet of the Host computer running the Client





Manager. The message will be telling the user of this difference in subnets. There are plenty of instanceswhere this is a legal configuration, so the warning message can be turned off by clearing this button.

Show Smoothed Link Test Results – If clicked, this option will average the Link Test result informationover 5 sample periods (i.e., a “smoother” response).

Use Sound During Link Test – If clicked, this option will produce different beeps at different frequenciesdepending on the Signal to Noise Ratio (SNR) of the Station. This will allow the user to listen for changeswhile adjusting the antenna position for maximum SNR.

Restore Options to Default – Pressing this button will restore all options back to their programmeddefaults.

3.3.3 Wizard Manager

The Wizard Manager screen (Figure 3.11) allows you to select a specific Wizard that will help youconfigure and display specific information pertaining to the EC and the network the EC is currentlyassociated with.

Universal Configuration Wizard – This Wizard is available in Release 3.0 and above of the ClientManager. It is designed to help you configure one or two ECs from the default configuration to theconfiguration that matches your needs. This includes the wireless and Ethernet settings.

Serial Configuration Wizard – Although there is a Wizard for Serial configuration, the EtherAnt does notuse a serial interface. All screens for Serial settings should be ignored since they are not applicable. TheClient Manager grays this option out.

Wireless Bridge Wizard – This Wizard is designed to help you configure a pair of Ethernet Convertersas a Wireless Bridge (Bridged) Network. This includes the wireless and Ethernet settings.

For detailed information about how to use each wizard to configure your EC(s) and the meaning of eachparameter on the different screens, Click F1 or the Help->Contents menu item. Under the Contents tab,select Using the Wizard Manager . Many of the parameters used by the wizard are covered in the nextsection (Configuration).





Figure 3.11 – Wizard Manager Screen

3.4 Configuration Screen

The Configuration screen features three buttons: Ethernet Configuration, Serial Configuration, andWireless Configuration.

3.4.1 Ethernet Configuration

This screen allows you to specify the parameters associated with the EC’s local Ethernet connection(refer to Figure 3.12).

Controller Name – This field sets a user-friendly name you wish to assign to the EC (up to 32characters).

MAC Address – This read-only property displays the MAC Address of the EC you are currentlyconnected to.

IP Configuration – This read-only field displays the type of IP configuration the EC is using. This willshow whether the EC is configured to use DHCP through the wireless interface (default value), DHCPthrough the Ethernet interface, or a static IP address that is configured with the Client Manager.

Static IP Address – This read-only field displays the IP address used for both local and wireless Ethernetcommunication when the EC is configured to use a static IP address or a DHCP server can not be found.

Subnet Mask – This read-only field displays the Subnet Mask used for both local and wireless Ethernetcommunication when the EC is configured to use a static IP address or a DHCP server can not be found.

Gateway – This read-only field displays the gateway used for both local and wireless Ethernetcommunication when the EC is configured to use a static IP address or a DHCP server can not be found.

Change IP Information – This button opens up a dialog box used to configure the IP information (seeFig. 3.13). The dialog box allows you to choose your IP configuration. You need to choose an IP address,subnet mask, and gateway even if you are using DHCP for the case in which a DHCP server can not be





found. You will only need to enter the IP address of your gateway for very specific configurations that arenot yet supported by the EC. Therefore, you can leave this field blank or set to 0.0.0.0.

Figure 3.12 – Ethernet Configuration

Figure 3.13 – IP Configuration

Automatically Search for Unknown Ethernet Addresses (ARP) –If this checkbox is checked, any IPpackets that are received on the wireless side that have MAC addresses unknown to the EC will causethe EC to first send an ARP (Address Resolution Protocol) message out the Ethernet side to find thecorrect route for that packet. If the checkbox is unchecked, you will need to tell the EC what the defaultroute is by filling in a MAC address in the Default Address textbox.

Default Address – This field sets the default MAC address that the EC uses to forward any IP packetsthat are received on the wireless side having MAC addresses unknown to the EC (only if the previous

checkbox is unchecked).

3.4.2 Serial Configuration

Although there is an option for Serial configuration, the EtherAnt does not use a serial interface. Allscreens for Serial settings should be ignored since they are not applicable. The Client Manager grays thisoption out.

3.4.3 Wireless Configuration

This screen allows you to specify the parameters associated with the EC’s wireless connection (refer toFigure 3.14).

Current Profile – This field allows you to select the profile name that identifies the settings for your

network. You can add, edit, or delete profiles. A profile is a combination of settings that you can defineand then use over and over.

Profile Name – This field represents an arbitrary identifier for each configuration profile you create (up to32 characters). The value in this field is for convenience in identifying multiple configuration profiles in theClient Manager. You should use a descriptive name that has relevance to your particular networkenvironment. Up to 1000 profiles may be stored within the Client Manager database. This database ispreserved when the Client Manager is upgraded.





Figure 3.14 – Wireless Configuration

Network Type – This field allows you to select the type of network that you will be connecting to. Theoptions from the drop-down menu are: Infrastructure if you are connecting to an Access Point, Peer-to-Peer if you are setting up an Ad Hoc group, or Wireless Bridge if you are setting up a wireless (bridged)network. Note: Wireless Bridge mode disables Micro-routing.

Network Name – This field allows you to enter the Network Name (or Extended Service Set Identifier,ESSID) that is set in your AP or the one that you will use to establish an Ad Hoc group. The NetworkName is used to specify a unique IEEE 802.11 wireless network. Wireless stations use the NetworkName to associate. Only devices with the same Network Name will associate with each other. Alphanumeric values may be used in this field (up to 32 characters). A Network Name of Any may beused in Infrastructure mode to associate with “any” open AP.

Encryption Enabled – If checked, this allows you to define the encryption keys that the EC should use toencrypt and decrypt data that will be transmitted via the wireless interface as shown in Figure 3.15. If notchecked, the Encryption function will be disabled.

Channel ID – This field allows you to set the Channel to use for wireless communication. This field onlyapplies to Peer-to-Peer and Wireless Bridge modes. When in Infrastructure mode, the EC willautomatically scan each channel for the AP.

Partner Name – This field allows you to specify which EC you will be creating a wireless bridge with.This field only applies to Wireless Bridge mode.

Distance – This field allows you to set the range of communication between two ECs in a Wireless Bridgeenvironment only. Select Normal Range for links less than 12 miles, or Extended Range for links greaterthan 12 miles.





Figure 3.15 – Encryption Enabled Screen

Encryption Keys 1 through 4– These buttons will bring up a configuration window that allows you to setup an encryption key (see Figure 3.16).

Use Key – This field allows you to choose which key to use for encryption.

Encryption Type – This field allows you to specify whether to use a 64-bit or a 128-bit encryption key.For a 128-bit encryption key use a 26-character hex key or a 13-character alphanumeric key. For 64-bitencryption key, use a 10 character hex key or a 5 character alphanumeric key.

Encryption Formats – The two formats used to develop encryption keys include hexadecimal oralphanumeric. Whichever format you choose, the key that you enter is used in an encryption algorithm toencode the data that you send. Only another wireless card using the same key can decode and receivethe data. Hexadecimal values are composed of the NULL character (0x00), 0-9, A-F and a-f. Alphanumeric values are composed of all printable ASCII characters.

Figure 3.16 – Configure Encryption Key





Encryption keys must be the same for all wireless stations. If you don’tuse the right key, you can establish a radio connection with another stationon your network, but you will not be able to send/receive data. All unitsmust conform to the least common denominator within the entire network.

NOTE: Any updated configuration settings will be retained even when the EC is powered off. Youcan then attach the EC unit to another device using the parameters you have already set.That device will not need to have the Client Manager installed because the settings arestored in the non-volatile memory of the EC.

3.5 Utilities Screen

3.5.1 Diagnostic Utility

The Diagnostic Utility Screen is invaluable for checking the reliability of the radio link. If you areassociated with an YDI or ORiNOCO compatible WLAN card in an Access Point or EC, you will also seethe signal levels of your Partner, typically the Access Point (refer to Figure 3.17).

Station Name – The name of the EC that you are connected to.

SNR (Signal-to-Noise Ratio) – The ratio measuring the difference between the signal level and the noiselevel.

Signal Level – This bar-field displays the amount of signal (in dB) communicated from the Partner EC.

Noise Level – This bar-field displays the amount of ambient interference (in dB) in the wirelessenvironment.

Figure 3.17 – Diagnostic Utility Screen

CAUTION





Partner Name – The name of the EC that you are communicating with.

SNR (Signal-to-Noise Ratio) – The ratio measuring the difference between the signal level and the noiselevel.

Signal Level – This bar-field displays the amount of signal (in dB) communicated from the EC you areconnected to.

Noise Level – This bar-field displays the amount of ambient interference (in dB) in the wirelessenvironment.

Sample Time – This field sets the time interval between diagnostic readings.

Clear – Clicking this button will clear the statistics displayed on the screen.

As diagnostic packets are received, the diagnostic utility screen will update the number of successfullyreceived packets at each specified rate.

These signal levels are also very useful for aiming the antenna. Adjust the aim such that you get the best

signal strength with the highest possible SNR. The signal levels appear as horizontal bars that changecolors depending on the strength of your signal. Green means an excellent signal; yellow means a goodsignal; and red means a poor signal.

If the Partner is an amplified base station, the weakest link will be the SNR of your signal into it.

3.5.2 Flash Utility Screen

This screen allows you to control the update process of the flash memory of your EC (see Figure 3.18).

Firmware Image File – This field will display all available firmware images that are located in theImageData folder, which can be found in the Install directory of the Client Manager. The most recentfirmware image will be automatically selected.

Update Firmware – When you press this button you start the firmware upgrading process. A FlashUpdate Progress Screen (Figure 3.19) will appear showing the different steps as they take place. Afterthe update process ends successfully, the CM will issue a reset command to the EC that will cause thenew program image to be loaded into RAM, and return to the Flash Utility Screen. The Firmware ImageFile should reflect the latest version that has been just upgraded.

If the update process fails, the CM displays a warning message clearly stating that the update has failed.The user should then attempt to log back in via the CM and re-run the update process. After the processis done and verified, the CM will issue a reset command to the EC that will cause the new program imageto be loaded into RAM, and return to the Select EC Screen. The Firmware Image File should reflect thelatest version that has been just upgraded.

Restore Factory Defaults – If checked, this box will replace any changes made by the user with the

defaults programmed from the factory.

Periodically, new firmware will be available for this device. When it is available, the Flash Utility Screen isused to load the new firmware. Simply follow the instructions in the center of the screen, and they willguide you through this process.

The latest firmware can be found at: www.ydi.com/support/downloads.php . (Firmware and ClientManager software are distributed together to ensure synchronized capability and features for smootheroperation.

1. Under the Start button on your desktop, go to Settings.

2. Click on Control Panel.

3. Choose Add/Remove Programs.

4. Select Client Manager .

5. The software will uninstall itself.

CAUTION

Do not ignore a warning message if the update process fails: this will causethe firmware to load a faulty image into RAM.If you power-cycle or turn the unit off after a faulty update, it will causethe EC to fail and require the unit to be sent back to factory for repair. Always log back in via the CM and re-run the update process as many timesas needed until it is successful before removing power or power-cycling the

unit.





Appendix A - Frequently Asked Questions (FAQs)

1. My EC keeps locking up and I need to cycle the DC power to it to bring it back. What is wrong?There were a number of bugs discovered that would cause behavior such as this under certaincircumstances. To solve this problem, you need to upgrade your firmware to Version 3.06 or greater.These issues have been resolved in this release. You can download the firmware from our Web site:


2. What is the Micro-routing feature built into the EC?The EC can support up to 253 Class "C" IP devices through a process called micro-routing. The algorithmmaintains an auto-indexed IP to MAC address table by inspecting each received 802.3 Ethernet frame.Thereafter, the EC's local MAC address is superimposed as the source address field within the frameprior to transmitting it on the wireless (802.11b) network. Whenever a wireless (802.11b) frame isreceived, the algorithm inspects the IP address and re-maps the associated MAC address into thedestination field of the frame. Finally, the source address field within the frame is replaced with the EC’slocal MAC address prior to transmitting it on the Ethernet network.

3. What do I need to do to flash upgrade the EC?First off, check your current version. If it is 2.3 and earlier, then you will need to make sure the IP subnet

of your computer matches the IP subnet assigned to the EC, and you will also need to have a directEthernet connection to it. (i.e., you are not trying to flash it wirelessly or on a heavily loaded network.)

To flash upgrade, download and install the latest Bridge/Client Manager (be sure to uninstall any previousversions before installing the new one). Select your EC in the scan window. Once it is connected andinitialized go to Utilities, and then go to Flash Utility. Make sure the latest version of firmware is displayedin the box, then click the Upgrade Firmware button. A dialogue box should appear displaying progress.

NOTE: If you get a failure message, do not power cycle the EC. Instead just keep trying the upgrade untilit goes through. Change the IP address on your PC if necessary. If the power to the EC is removedbefore the update is completed successfully, then it will reboot with trashed ROM image, which can onlybe fixed at our facilities.

4. Why can I not log on Bridge/Client Manager?

Only one Bridge/Client Manager Login is allowed at a time. The manager program will not allow two usersto log on simultaneously.

5. Why does my EC seem to reduce its transfer speed sometimes?Transfer Speed is reduced when the Bridge/Client Manager is logged into an EC (approx. 25%). Youshould not leave the manager program logged in continually. The program was designed to configureand test the EC. It is not recommended that you leave it logged in during normal operations: a substantialreduction in data transfer performance – approx. 25% – will be experienced when the Bridge/ClientManager is logged into an EC.

6. The settings of a Profile do not match what I previously entered.If multiple ECs contain the same Profile Name, but different Profile settings, the Bridge/Client Managerwill inherit the settings of the last EC to which it was connected.

7. Why do I lose my WEP keys?Previously stored WEP keys will be lost when re-configuring an EC (via any wizard).

8. I’m entering information in a field of the Bridge/Client Manager and the program does notrecognize it. What’s wrong?

When entering information into the various fields of the Bridge/Client Manager, be aware that those fieldsare case-sensitive (upper/lower-case).








9. The changes I implemented to my EC configuration do not show. Any changes made to the configuration of an EC will not be stored in the EC until you save the changesusing the ‘Save Settings’ button.

10. How long does it take to an EC to re-associate with a new Access Point (or Wireless Link)?The EC may take up to 15 seconds to automatically scan and re-associate with a new Access Point (orWireless Link) when the primary association has been lost due to marginal link conditions.

11. What happens if a targeted AP (or Partner) is not discovered?When configured for Infrastructure mode (or Wireless Bridge mode), if the targeted AP (or Partner) is notdiscovered the EC will revert to Peer Group mode after approximately 15 seconds. Thereafter, the EC willre-scan for the target every 4 seconds.

12. How many devices can be attached to the EC if I use the ‘”Dynamic MAC Address” selection?When configuring an EC to use Dynamic MAC Address, make sure that only one device is attached to theEthernet port (RJ45). There are very few instances where you will ever want to use Dynamic MAC. Thismode disables the Micro-routing feature.

13. Why do my client devices keep wandering off for Access Points?When configuring your APs with the Orinoco AP Manager, under the "Wireless Interface -> Advanced"

tab there is a parameter called "Distance Between APs". This parameter needs to be set to the defaultvalue of "Large", meaning there are not many APs covering the area. This keeps client devices fromeasily wandering off looking for other APs if there is any kind of transient interference.

The settings Medium or Small distance between access points require an excellent quality of radiocommunications throughout the entire wireless coverage area. In environments where the actualplacement of access points was designed to obtain maximum wireless coverage with a minimum numberof APs, changing the distance between access points from Large to Medium or Small will not yield betterresults. Adversely, doing so might seriously affect the roaming performance of your wireless stations,risking network communication errors caused by “out-of-range” situations.

Be also aware that the setting for distance between access points must be the same for all APs in yourwireless network. A mismatch in the configuration setting for this parameter may have unpredictable

performance results for wireless (mobile) stations in your network.

14. Bridge/Client Manager scans for EC’s and when it finds one and I select it, by using the Selectbutton or double-clicking on it, instead of opening the main window it starts scanning for EC’sagain repeating this cycle indefinitely. What’s wrong?

There are several possible causes for this. First, the Bridge/Client Manager uses both UDP and TCP toconnect to the EA, so if there is anything on the computer that is blocking either of them then there will bea problem. Typically if the EA does show up in the scan this is not the case, however there areexceptions. Firewall software is the primary culprit in these cases so make sure there is none running onyour computer, including XP's built-in firewall which could be on without you knowing.

The Bridge/Client Manager will manipulate your routing table in order to allow you to connect to the EC nomatter what IP subnet it is on. If this mechanism fails for any reason you can run into this problem.

Specifying an IP on your computer within the same IP subnet as the EC will often solve this (test yourconnection by pinging it).

In a couple of rare cases, problems with the drivers of the Ethernet interface on the computer causedproblems. Updating the drivers fixes the problem.

If it is only one EC that is causing the problem, see if you can get it to associate to an AP, then you couldprobably get into it from a remote connection. Perhaps a restore to defaults would bring it back to life.

Also, make sure that you are running the latest version of Bridge/Client Manager.





15. When I log in on my system management station under Windows 2000 (or XP) and I startBridge/Client Manager v3.09 I get the error message: “Failed to log on”. This didn’t happenwith previous versions of the program. What’s wrong?

The latest version of the Bridge/Client Manager (v3.09) incorporates an automatic ARP Table Entrykernel system call to speed-up the connection process and minimize ARP request traffic. Since thisinteracts with operating system resources in ways that previous versions did not, the computer you areusing to run the program must have appropriate permissions. Specifically, if you log in on a Windows2000 or XP station you must do so with power-user or higher privileges, otherwise you will get the errormentioned above when you try to run the Bridge/Client Manager from that station.

16. I’m running Bridge/Client Manager on a Windows XP computer. Initially it has been workingfine but with time it stops scanning for EC’s. What’s the problem?

Check if you have a third-party application add-on called “Deterministic Network Enhancer” installedunder Windows XP. Its purpose is to filter Ethernet packets. This may lead to some unwanted filteringsince the service will eventually remove the EC replies to the Bridge/Client Manager. If this is the case,uninstalling the application and rebooting the PC afterwards will solve the problem.

17. I have an EtherAnt-II mounted on the same mast as a TV antenna. When I operate the unit,lines appear in my TV set. How can I fix this?

The only way is to move the EtherAnt-II away from the TV antenna since the electronics in the device areemitting weak spurious signals that the TV antenna is picking up because they are so close. Experimentwith distance until you get a better reception.
