OK, I couldn't resist so I reinstalled the SR71-E and tested again. 802.11g seems to be working fine now. I get 7.75Mbit/s from 802.11g. I get 5.25Mbit/s from 802.11b and anywhere from 3-4Mbit/s from 802.11n so I think I have an interference problem on channel 11. I get 10-13Mbit/s from 802.11n on channel 1. I can't get 5Ghz to work at all so I'll start a separate thread for that. - Grant > Adrian > > On 14 August 2011 02:59, Grant <emailgr...@gmail.com> wrote: >>> 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 at best >> 3. the performance of 802.11b in AP mode is good, about 4.5Mbit/s >> >> The same iperf tests with a Netgear ath5k card: >> >> 1. the performance of 802.11g in AP mode should be better, about 5.5Mbit/s >> 2. the performance of 802.11b in AP mode is good, 4.5Mbit/s >> >>> I'm noticing some strange issues in FreeBSD with the SR71-E, but >>> nothing which would cause that kind of performance issue. >> >> What sort of things are you seeing from the SR71-E? >> >> - Grant >> >> >>> Thanks, >>> >>> Adrian >>> >>> On 13 August 2011 12:33, Grant <emailgr...@gmail.com> wrote: >>>> Using my ISP's throughput test: >>>> >>>> http://speedtest.oceanic.com >>>> >>>> I get drastically better performance from my Netgear ath5k card in AP >>>> mode compared to my Ubiquiti SR71-E in AP mode.
