Comment 30 for bug 284354

Just a random note: ath5k seems not to be disabled by default as the last few comments in this thread imply happened for Intrepid's release. I have not previously used used ath5k, and yet after I upgraded to Intrepid, it was now loaded and breaking my working ath_pci setup. (Atheros AR2414 chip, using wpa_supplicant).

For Ubuntu upgraders who have a suddenly broken wireless connection with Atheros hardware:

-Do a "lsmod | grep ath" and see if both ath5k and ath_pci are loaded.

-If they are, do "rmmod ath5k", "rmmod ath_pci", "modprobe ath_pci" and then try to bring your wireless connection up, perhaps by "ifconfig ath0 up".

-you can see what's happening with "cat /var/log/kern.log" and "dmesg | grep ath"
