WiFi goes off after boot

I have two kernels - regular ARCH kernel, and a linux-pf kernel which I use 99% of the time.

The problem is, than whenever I boot with the -pf kernel, the WiFi radio becomes disabled 1-2 minutes after boot, loosing all connectivity (even if it is already connected to a network). I then have to go into WICD, enable radio, refresh, and then connect to network again. The problem occurs after EVERY reboot, but never upon resume.
This does not happen if I boot from regular kernel.

What could be causing it?

Re: WiFi goes off after boot

If you have a broadfailure card, you will probably need broadcom-wl-pf-core2.

Re: WiFi goes off after boot

You can check power-saving status when it is connected with "iwconfig".
Also you can describe shortly what you have tried to find out the reason and if the logs give strange non-broadfailure output upon disconnect.

Re: WiFi goes off after boot

Power Management:off
Apparently, driver for this card does not support Power Management.

Which log file should I be looking in?

Re: WiFi goes off after boot

... hopefully you know you have a /var/log folder yeah?  What is in there?  I would suggest checking out messages.log and everything.log as a place to start.  My system also has a wicd folder in which it stores wicd related log files.  So... poke around and see what you get.

Some of the first lines might be from the previous session from before the reboot.

Re: WiFi goes off after boot

The same in my case, after the last kernel upgrade. Broadcom BCM4313 card.
Check also the state with rfkill - ie. with

rfkill list
