[SOLVED] ath9k & new kernel 3

Hi,

After changing kernel from 2.6 into 3 (3.0.6-gentoo x86_64) I have problems with wifi on my laptop.

As usually I did module-rebuild populate & module-rebuild rebuild, but...

(1) I tested this few times and module ath9k is ALWAYS loaded automatically with kernel 2.6 after starting the system, but with kernel 3 this module is loaded automatically ONLY when in file etc/conf.d/modules is added a line -> modules="ath9k". Without this after starting the system (with kernel 3) I have to add module manually by typing modprobe eth9k.

(2) With kernel 2.6 after starting the system I have an interference wlan0 and I can use my wifi by WiCd, but with kernel 3 I have an error (either after loading module automatically or manually)

Code: Select all

# ifconfig wlan0 
 wlan0: error fetching interface information: Device not found

...and I can't use wifi

What should I do?
Why, even if I have module ath9k, I can't use wifi?

Code: Select all

# lsmod 
Module                  Size  Used by
ath9k                  68260  0 
ath9k_common            2360  1 ath9k
ath9k_hw              274717  2 ath9k,ath9k_common

Moved from Kernel & Hardware to Duplicate Threads in favor of the thread marc_alec identified.
