More fun with attenuation and ath9k:
It seems that the tx-rates do not properly go to lower speeds,
at least in some cases.
I enabled lots of attenuation, and it gets into a state where the
station drops rates down to around 100Mbps, but the AP side stays with
high tx-rate. From sniffing, it seems that STA starts sending ARPs to AP,
and AP responds, but packet is never received on the STA. I *do* see lots
of rx-crc errors on the station.
If I force the rate to be MCS-0, then it runs just fine. I haven't yet
tried forcing it to run at higher rates.
This is kernel 3.5.5+...any ideas on what parts of the code need poking
at to figure out why it doesn't decrease the tx-rate?
Station 00:0e:8e:32:12:cf (on vap0)
inactive time: 2048 ms
rx bytes: 3145942974
rx packets: 2145073
tx bytes: 3392161604
tx packets: 5245999
tx retries: 30925
tx failed: 882
signal: -77 dBm
signal avg: -76 dBm
tx bitrate: 360.0 MBit/s MCS 21 40Mhz short GI
Thanks,
