GeckoV4 4.0.5 build 5542 released (public beta)
There is a new GeckoV4 release available for download.
Changes since 4.0.5
*) Atheros 11n now support AMSDU-TX (in addition to AMSDU-RX) for higher performance (enabled automatically). - see notes below
*) Sync option now applies the AP's local distance option live and is not propagated to clients.
*) Fixed a scan & connect issue with HT5 / HT10, where a client would sometimes fail to connect to an AP using a frequency > 5700 Mhz.
*) Many Atheros improvements to assist in performance.
** MIPS-COMPEX support is not available in this release, but will be in a future update.
This feature Aggregates MAC Service Data Units (AMSDU) to increase TX performance on your link. Since this is a service unit aggregation, small packets (100 bytes or less) of the same QoS class will be aggregated to increase performance. This increase is quite noticeable with TCP (via aggregating return ACKs) and UDP (VoIP) traffic.
The AMSDU feature is prone to failure with high error rates on weak links, however we have countered this with a robust transmit and retry scheduler that should keep things balanced. Because of this new scheduler, you may notice a slight increase in system load which is nothing to be alarmed about.
This feature is not tunable at this time, and is enabled by default when AMPDU Aggregation is selected.
Licensed Frequency support (LF country code) is almost complete, and should be available in a release soon.
Please post your results in this thread.
