1. IntroductionOpenWifless ESS ProNODE version 1.45.T2 introduces several new features, improves a lotthe system performance and fixes know bugs & limitations.

2. Compatibili ty and InteroperabilityOpenWifless ESS ProNODE version 1.45.T2 is compatible with the following hardware:

Wifless ESS 24561, any HW Rel.



Do NOT install on the new Wifless ESS PN25x devices!

The upgrade procedure to OpenWifless ESS ProNODE Ver. 1.45.T2 is compatible with theprevious operating system versions from 1.40.T1 to higher intermediate patch versions up to1.45.T2.B312.

However, in same cases the configurations cannot be automatically upgraded to thenew version and a user intervention is needed to adjust the configuration.Check carefully the behavior of your system after the upgrade to verify that it is perfectlyworking as expected.

Upgrading from releases lower (older) than the 1.40.T1 could require a system reset to factorydefault and the manually reconfiguration of the device.

Using CPE running OpenWifless ESS CPE operating system releases lower (older) than1.00.T3 must enable the 802.11 Reg. Domain option in the wireless settings of the AP.Failing to do this may lead the system to not correctly connect all the CPE of the sector.

Operating this new OpenWifless ESS ProNODE version, it is kindly suggested to upgrade yourEssentia Wifless CPE at least to the OpenWifless CPE version 1.10.T2.B338, or better to thelast version available at the time.

3. Documentation and Firmware Availabili tyThe information in this release note is complementary to the products documentation and tothe Basic System Manual Essentia Wifless ESS PN25x (HW All) & ESS 2456x (HW 2.1x)Basic System Manual - OpenWifless ESS ProNODE Ver 1.45 - 20090120.pdf provided in theproducts documentation CD Rom and downloadable from www.essentia.eu at the followingURLhttp://www.essentia.eu/download/download.aspselecting the search option Manuals.

4. New Features and Improvements compared to ver. 1.40.T1

General GUI ImprovementsWeb GUI has been improved for a better lookout and usability.Dedicated web pages have been added to address specific settings and/or to speed

up the device provisioning.

General Performance ImprovementsFurther optimization of the Atheros HAL and Madwifi driver.Optimized the IEEE 802.11 radio protocol timing and the WMM implementation.Improved the Radio system efficiency of about 15%.Optimized the Linux OS porting or the networking related stacks: improved thesystem efficiency of about 20%.Improved ETSI Radar Detect algorithm to reduce the False Positive Detections.Up to 95 Mbps of UDP traffic per radio sector over 20 MHz radio channel, with 1470bytes long packets, and up to 130 Mbps over 40 MHz radio turbo channel.Up to 65 Mbps of TCP traffic per radio sector over 20 MHz radio channel, with 1450

bytes long packets.Up to 38 kPps per radio sector with 64 bytes long packets.

System web tab/pageAdded System tab entry, under Devices menu, to provide settings of PCI Latencyand Secondary Watch Dog control.

DFS Disable optionAdded DFS Disable option available to disable DFS and Radar Detection activity.ATTENTION! Important Legal Note!The disable option has been added for troubleshooting purpose and for specialapplications only.ETSI and FCC Rules strictly require to have DFS Enabled under normal operation.Contact your Local Radio Regulatory Authority for information.

ACK Fast Rate optionAdded ACK Fast Rate option to handle acknowledges packets with higher rate (upto 36Mbps instead of the standard 6Mbps).

Multicast Rate Selection and Max HW Retries optionsAdded Multicast Rate Selection option on the Radio Web GUI.Added Max HW Retries option on the Radio Web GUI.

Trunk & PTP Link optionNew Trunk & PTP Link option introduced to optimize the performance under PTPoperation.

PPPoE Server featureImplemented a fully featured PPPoE Server.(See also Known Bugs & Limitations at the paragraph Fast-Frame setting inPPPoE Server configuration).

getinventory utilityImproved getinventory utility adding the reporting of more details.

NAS IP AddressAdded the Radius NAS IP Address attribute.

5. Main Fixed Issues from ver. 1.40.T1

Device self-Reboot under heavy Radar Detect conditionDue to a brute-force implementation of the ETSI DFS & Radar Detect algorithms,has been noted that the under heavy radar detect conditions the kernel processes

were starving on those and the Secondary Watch Dog wrongly rebooted the device.New ETSI DFS & Radar Detect algorithms now avoid the problem.

MAC Addressed Table wrong updated bugThe problem, also known as ARP Bug or Not operating ARP bug has been fixed.

IP Multicast drop bugThe problem, also known as Multicast Bug, related to the wrong dropping of someMulticast IP packet on the ETH0 and ETH1 Fast-Ethernet ports, has been fixed.

WDS Node Configuration SettingsWDS Node operating mode is now working as expected.

Ad-Hoc Node Configuration Sett ingsAd-Hoc Node operating mode is now working as expected.

Radio Trunk Configuration SettingsRadio Trunk Mode is now working as expected also when two (2) adjacent channelsare used.

.11g Mode TX Rate Information Web Disp lay BugWhen Fixed Rate 802.11g mode is operating, the link TX Rate Information is nowcorrectly displayed in the WEB page.

SNMP Private MIBs ImplementationEssentia SNMP Private MIBs are now fully implemented.

Turbo Mode(s)FCC Turbo Mode is now working as expected.ETSI Turbo Mode, as allowed by ETSI EN 301 893 V1.4.1, is now implemented.

Memory Leakage and IRQ LoadUnder some circumstances has been noted a memory leakage, and sometimes alsoan unexpected increase of the IRQ Load.

A better memory management and the improved Linux OS efficiency solved theseproblems.

WMM Aggressive ModeWMM Aggressive Mode is now working as expected.To avoid problems by not expert users it is now disabled by default.

6. Known Bugs and Limitations

Wrong Measurement of SNR and Noise LevelDue to bugs in the new Atheros HAL the SNR and the Noise Level are wronglyreported. Displayed SNR is about 6 dB lower than the real value and the Noise

Level is about 4 dB lower than the real value. Consequently, also the RSL iscalculated about 10 dB lower than the real.This problem only affect the displayed/reported values, but it is not service affective.Workaround: n.a.

Loss of Ping to Bridged InterfacePinging a device bridged interface may lead to unexpected high rate of ping losses.This problem is not traffic flow or service affective.Workaround: n.a.

WMM setting in Trunk configurationWhen Trunk configuration is required, WMM must be disabled

Otherwise the Trunk performance are very bad and asymmetric.

in AP and Station

interfaces and the QoS must be managed via the Trunk Logical Interface.

Workaround: Ask for the bug fix yet available from the Wifless Support Team.

Atheros Extended RangeAtheros Extended Range is not fully implemented yet.Workaround: n.a.

NTP/SNTP ServerNTP/SNTP embedded server current implementation requires to get the referencetime from an other NTP/SNTP.

Current implementation does not allow to get the reference time from the embeddedreal time clock/calendar.Workaround: n.a.

IPERF ServerTCP IPERF Server when enabled in the Web is not working as expected.Workaround: Use NETPERF or enable IPERF server service via SSH issuing thecommand iperf -s (-D option to load it as a service).

IPERF ClientUDP IPERF Client when test started from the Web is not working as expected.Workaround: Use NETPERF or IPERF client service via SSH.

Single Repeater configurationSingle Repeater configuration (AP and Station created on the same radio physicalinterface) is not working as expected.Workaround: Use Dual Repeater configuration (AP and Station on different physicalradio interfaces).

Fast-Frame setting in PPPoE Server configurationPerformance tests report that the implemented PPPoE Server can deliver up to 150Mbps of throughput when delivering traffic to/from the Fast-Ethernet ports, while it iscapable to deliver only up to 15 Mbps only of throughput when delivering trafficto/from the Radio Interfaces when Radio Fast-Frame is enabled.Workaround: Disable Radio Fast-Frame setting.

Trunk XOR Mode TCP performance

Throughput tests report that the Trunk XOR mode performances using TCP are notexactly symmetric as expected.Workaround: If symmetric performances are required, use Radio Optimized Trunkmode or use an external device, L2 switch or L3 router, doing the requiredaggregation.

Trunk Round-RobinTrunk Round-Robin Mode is not working as expected.Workaround: Use a different Trunk mode or an external device.

802.1X with Dynamic WEP802.1X with Dynamic WEP is not working as expected.Workaround: If 802.1X is required, use WPA Enterprise mode. If WEP is required,use Open/Shared WEP.
