Comment 5 for bug 353973

I haven't installed the LBM modules, but the channel 12/13 is also missing after startup with the
"default"? ath5k kernel module
filename: /lib/modules/2.6.28-11-generic/kernel/drivers/net/wireless/ath5k/ath5k.ko
version: 0.6.0 (EXPERIMENTAL)
license: Dual BSD/GPL
description: Support for 5xxx series of Atheros 802.11 wireless LAN cards.

To fix this, i did:
ifdown wlan0
modprobe -r ath5k
modprobe ath5k
(if up wlan0)

After that, all 14 channels are active.
see attachment ath5k-channel-fix.txt for details
I think, it is not a good solution, but it works (e.g. /etc/rc.local)

Anyone knows the correct solution for this bug?
