Wireless problem: Device or resource busy

I'm really fed up with wireless(BCM4312) issues. One day ago, wireless was working perfectly.
However, today, it says "Interface doesn't support scanning : Device or resource busy".
Additionally, whenever my wlan0 interface is up, my laptop becomes slow. I put it down, everything is normal.

Thanks

# iwlist scan

eth0      Interface doesn't support scanning.

wlan0     Interface doesn't support scanning : Device or resource busy

Whenever wlan0 is up, pc hangs for 1 second every few seconds. I turn it off, pc goes smooth. It's really annoying.

Re: Wireless problem: Device or resource busy

Given the timeframe I'm wondering whether this may be caused by a regression in kernel26 2.6.32.

Could you confirm the kernel version you're using, and if running 2.6.32, test whether the problem also exists in 2.6.31?

Yes, I'm using 2.6.32. I don't have 2.6.31.

Re: Wireless problem: Device or resource busy

you have to rebuild the driver for the new kernel. The package is here. To build the package you need to download the kernel headers.

Re: Wireless problem: Device or resource busy

I have already tried this driver and it didn't work with me.
Anyway, this is stupid and frustrating. I'm reinstalling the whole system.

Same problem here. With previous 2.6.31 worked just fine with this AUR package. But with upgrading to 2.6.32 it stopped working (I tried recompile that AUR package - but it didnt work - also I tried AUR packages b43-firmware-newest and b43-fwcutter-pathced (wlan0 interface) with same status) with same "Device or resource busy" or  iwlist scan showing:

# iwlist scan
lo        Interface doesn't support scanning.

eth0      Interface doesn't support scanning.

eth1      Failed to read scan data : Invalid argument

What should I do? I dont want to reinstall whole system.

Re: Wireless problem: Device or resource busy

I had the same problem, but I think I've found a fix for it. I think everything is fine, but the interface to your wireless card is deactivated. You can enable it with the following:

sudo ifconfig eth1 up

I don't know why it is shut down by default.

Hope that solves your problem!
