I'm trying to build a kernel with this Atheros AR9287 wifi card. I had it
working last week and rebuilt the kernel without saving my config, now I'm kind
of stuck.
The most immediate problem I see is that I have /proc/net/wireless, even though
when I boot with SystemRescueCD it comes up fine.
Thanks in advance! (Here's the info I have, feel free to query for more):
- iwconfig wlan0 # On the bad boot
wlan0 No wireless extensions
- dmesg | grep -i ath # Same both boots (except for timestamps)
