Public bug reported:

Upon upgrading the Alpha 5 of Karmic Koala, my wireless network chip is
not detected. In Jaunty, the card was detected fine.

Running "lspci" shows the chip:
03:00.0 Ethernet controller: Atheros Communications Inc. AR5212 802.11abg NIC 
(rev 01)


However no wlan0 is present in the system when running ifconfig:

The installation of Karmic was done as an upgrade from Jaunty via 
"update-manager -d"
