Cannot connect to wireless after wakeup from sleep

When my laptop wakes up from sleep, I can't connect to wireless again.

Re: Cannot connect to wireless after wakeup from sleep

Hi,

same problem over here. Reloading brcmsmac does the trick:

sudo modprobe -r brcmsmac ; sleep 1 ; sudo modprobe brcmsmac

This used to work, so maybe it's a regression in recent kernels or udev or whatever. I haven't had a closer look.

Re: Cannot connect to wireless after wakeup from sleep

Hey,

same problem with my samsung netbook. Probably a regression. Have anyone of you tried with the newer kernel?
