my config: Ubuntu Natty Kernel 2.6.38-X Wifi pci card: Atheros Communications Inc. AR5008 Wireless Network Adapter (rev 01) Hello, I'm using Ubuntu Natty and the ath9k driver of the different kernel of this distribution do not make my AR5008 pci express wifi card run well: the connection is too slow or halted. I tried to compile Compat-wireless but it does not compile: #./scripts/driver-select ath9k Processing new driver-select request...

But it is not stable, I lost the connection several times per day. In dmesg, I can see: [125508.616378] ath: Failed to stop TX DMA in 100 msec after killing last frame [125508.616429] ath: Failed to stop TX DMA!

Someone know why I can only compile this version? not the last? Thanks for your help.
