Under stock Ubuntu 9.04, my AR5008 card is picked up and sees my 5 GHz
802.11n access points, as well as my 802.11g access points. I do not
know the precise driver configuration (just booted live disc) but
clearly this demonstrates the card is working fine. OS X also agrees.
Under Debian with a 2.6.29-2 kernel and compat-wireless built from
yesterday's nightly, CRDA and regulatory.bin, I cannot pick up my
802.11n access points on channels 149 and 157. Moreover, I am having
weird problems with channels being disabled that should not be
disabled, e.g. everything from 100 to 140 is disabled, even though my
regulatory domain allows those channels. I thought this was a DFS
issue, but 52-64 requires DFS and those channels ARE enabled, so I
doubt that's the case.
Can anybody clarify the situation here?!
