------------------------------------
The problem is that I need to use the ath9k driver with this card. ath9k
is only available for 2.6, but when I run a 2.6 kernel, the card - and I
guess the entire PCI bus - completely disappears. It's visible in 2.4 -
but I have no driver!
I installed the SR-71A card into my laptop running a 2.6.27 kernel. The
card was detected just fine. The card also works with a recent version of
DD-WRT, which runs a recent 2.6 kernel. I have posted a topic on the
ubiquiti networks forums, but I feel like this seems to be a bug with
openwrt.
Help!
