[SOLVED] Kernel 3.4.24: WLAN stopped working

[htgoebel]

Hi,

I'm running Mageia 2. When updating the Kernel 3.4.24, the WLAN stopped working.

It keeps setting the regulatory domain on and on. /var/log/messages contains lots of these entries, one after each other. DHCP does not get a chance fetching an IP-address and thus comminication is not possible,

Code: Select all

kernel: [  155.897029] cfg80211: Calling CRDA to update world regulatory domain
kernel: [  155.933630] cfg80211: World regulatory domain updated:

A (mostly) complete logfile (network-stuff only) can be found at http://pastebin.com/dReYL1ug

The solution is weird, but simple: This always happens if the WLAN-keys is invalid. Argl! I did not discover this, as it not only happened at a WLAN I used to have the key (but has changes meanwhile), but also at my home-WLAN.

It's a bit sad that drakroam does not log a meaningful message, so the other log messages could fool me.
