Oh, I see fine 11g behaviour. Can you do some iperf tests both to and from the AP, and contrast? (ie, with the AP mostly TXing, and the AP mostly RXing.) Adrian On 14 August 2011 02:59, Grant wrote: >> Can you try doing some iperf testing to a local linux box, through the APs? > > Here's what I

> Can you try doing some iperf testing to a local linux box, through the APs? Here's what I came up with pertaining to the SR71-E: 1. the performance of 802.11n in AP mode is good, about 15Mbit/s 2. the performance of 802.11g in AP mode is horrible, very unreliable and just a few hundred Kbit/s a

Hi, I'm not sure whether you have found a solution to this issue yet but I thought that I should share my findings. I'm running Arch linux on my laptop which have the AR9280 and I saw massive packet loss as well. I noticed however that this _only_ occurred when the laptop was on battery power. So

Can you try doing some iperf testing to a local linux box, through the APs? I'm noticing some strange issues in FreeBSD with the SR71-E, but nothing which would cause that kind of performance issue. Thanks, Adrian On 13 August 2011 12:33, Grant wrote: > Using my ISP's throughput test: > > http
