Thanks, Lukas > According to my interpretation the calculation should depend > on channel width (20MHz in normal mode, 40MHz in turbo mode, same for 802.11g > and 802.11a), not on MAC chip clocks. thanks, then my guess was irrelevant... I got some improvement (even not so significant), but I might have mislead myself at this moment . let me show my observation during last a few days. at first - chip is AR5414 - I pulled down codes via git a week before and your recent patches were applied. then what I have observed till now was 1. stable and excellent throughput for 5GHz (with 1hop and also 2hops cases) 16Mbps(1hop) , 8Mbps(2hops) note: testing with IBSS ad-hoc mode, 1 hop, 2hops , 3 hops.. 2. still not good and unstable throughput for 2.4Ghz thanks to your patch[3/5], [4/5], throughput was improved pretty much but still staying around 10~15Mbps(1hop), 1Mbps~6Mbps(2hops) without my experimental patch, 2hops throughput was worse than the case with that patch. ( 1~2Mbps vs 1~6Mbps --> I can't say this difference is significant ) . debugfs(rc_stats) shows minstrel reported around 85%~95 success rate with 48/54Mbps and selected low xmit rate. (this was the result on limited number of tests. five ~ ten times ) in my these tests, node is sitting pretty close (1m) to each other, therefore I did not enable RTS/CTS and just counted on physical carrier sense. Does it seem that there still exist vulnerable part around carrier sensing for 2.4GHz.? anyway, I would like to get back to this issue, again later thanks Taka -- To unsubscribe from this list: send the line "unsubscribe linux-wireless" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
