No wireless with maxcpus=0

Hi!

I’ve been struggling now a few days with a USB mouse, external hard drive etc. that wasn’t working properly. So now finally it was started to work by adding “maxcpus=0” to the boot.

But, when I do that my wireless stops working… If I right click the tray icon I get “Enabled Wireless” which is checked and of course “Manage connections”, but there seems to be now way to add a connection to my wireless network. :S

This problem also occur when I boot in failsafe mode.

This is what hwinfo says about my wireless card (note that Im not using maxcpus=0 when gathering this data, dunno if that is necessary?):

Anyone got any idea on how to get my wireless back on its feet while I still can be able to use maxcpus=0? :slight_smile:

Tried to restart my computer and now the wireless tab in the network manager is enabled but when I try to add a wireless connection there is no interface to pick.

This is what dmesg gives me:


linux-qduk:/home/jesper # dmesg | grep ath5k

Any ideas? :slight_smile:
