with the kernel 2.6.26-2-amd64 my wireless connection (on ath1 ) works
after a recent upgrade with the kernel 2.6.32-trunk-amd64 (on wlan0) my

I think ath1 is a madwifi-device whereas wlan0 is from the native
linux (free) ath5k driver. I'm guessing madwifi was working until you
switched to kernel 2.6.32 (cause it works perfectly fine with kernel
2.6.26) and now doesn't load anymore but loads the native linux
drivers (wlan0 on ath5k, my guess) instead, which - as far as I've
experienced it so far - don't work so well at least with my

I'm stuck with kernel 2.6.26 because so far I haven't managed to get
either madwifi working with kernel>2.6.26 or to get the native linux
drivers for my card to work reliably enough. - It keeps cutting out on
me after 1/2h-1h, forcing me to reload all the related modules or
restart, I'm not sure if that's the driver, my router - which I don't
trust either, or just misconfiguration on my or wicd's part. So far I
just couldn't get the madwifi-modules to build for newer kernels

I'd be most interested to hear of anybody that has one of the
ath(_pci|5k)-cards and got it working properly with either madwifi and
kernel>2.6.26 or the native linux drivers. Please mail me, either on
this list (if appropriate) or @ following address:

for me : lspci | grep -i athe 06:02.0 Ethernet controller: Atheros Communications Inc. AR2413 802.11bg NIC (rev 01)

and my wireless connection works fine with wlan0 and the kernels:
2.6.30 , 2.6.31, 2.6.32 except with the last kernel 2.6.32 (2.6.32-3)

So I wonder if this is a kernel bug ?

happy new year 2010 to all.
