I encountered the same issue on 3.2.0-4-amd64 dmesg : ath5k phy0: Atheros AR2425 chip lspci : Ethernet controller: Atheros Communications Inc. AR242x / AR542x Wireless Network Adapter (PCI-Express) (rev 01)
My solution : Add # Backports deb http://ftp.debian.org/debian/ wheezy-backports non-free to your sources.list ( replace url with your favourite repository ) then sudo apt-get update sudo apt-get install firmware-linux-nonfree Hope this helps. -- -- Cas Renooij
