[ath9k-devel] AR9285: Possible intermittent connection drop-outs

[Dan Borlovan <danb@level7.ro>]

Just got a DIR-615 router and a free ticket into the "mee to" vagon. DIR 
running 4.11 configured as AP only

AR9285 (eeepc 1005p)

Ubuntu 10.10 kernel 2.6.35-22, with and without compat-wireless-2.6.35-1

If the AP is set to 20/40MHz I connect at 150Mbps but every few minutes 
I have long intervals in which no packet goes by. Link stays up, nothing 
in dmesg. No matter if wlan0 powersaving is on or of. Long term packet 
loss with the AP around 11-14%. A few times ifconfig wlan0 showed 1Mbps.

BUT if I switch ap to 20MHz only I connect at (only) 65Mbps with no 
problems.

Under windows 7 no problems so far.

This is one of the "pauses"

64 bytes from 10.0.0.14: icmp_req=74 ttl=64 time=0.979 ms
64 bytes from 10.0.0.14: icmp_req=75 ttl=64 time=1.40 ms
64 bytes from 10.0.0.14: icmp_req=76 ttl=64 time=5.29 ms
<here comes the pause>
64 bytes from 10.0.0.14: icmp_req=168 ttl=64 time=44.4 ms
64 bytes from 10.0.0.14: icmp_req=169 ttl=64 time=1.06 ms
64 bytes from 10.0.0.14: icmp_req=170 ttl=64 time=1.00 ms

Is this by any chance fixed in newer kernel/compat-wireless or for now 
there is no hope for me?
