Hi all! I am posting a solution to a problem I ran into installing Gentoo.

The Dell Inspiron N5040 uses the Atheros AR9285 wireless card. When I installed Gentoo and ran iwconfig, I got the following:

Code:
wlan0:     no wireless extensions.


This was despite having the appropriate kernel module (ath9k) loaded. The solution I found was to downgrade to an earlier kernel version. I am now using version 3.2.39, and my wireless card works correctly. (This is probably not the most recent working version; it's just the one I picked.) The following is my kernel config:

Code:
[*] Networking support --->
  [*] Wireless --->
         <M>   cfg80211 - wireless configuration API                     
         [ ]     nl80211 testmode command

My /etc/conf.d/modules reads:
Code:
