Broadcom 4321 intermittent cutoff when changing power state for most parta

Hi, still seem to have a problem with BCM4321 device dropping out intermittently and I can’t resume unless I reboot.

What happens is I’d get disconnected and the wireless card will disappear - no chance to reconnect via NetworkManager.

rcnetwork restart won’t restart the wirless

OS: Opensuse 11.4 Celladon

rcnetwork restart shows:



Kernel driver in use: k8temp
03:00.0 Network controller [0280]: Broadcom Corporation BCM4311 802.11b/g WLAN [14e4:4311] (rev 02)

I suggest you switch to the ‘wl’ driver

Follow this guide
Install Broadcom Drivers from Packman

For a 4311, wl is not necessary, and will introduce an extra level of complexity.

First of all, a reboot is seldom necessary. Run the sequence


sudo /sbin/modprobe -rv b43
sudo /sbin/modprobe -v b43

That should recover from most situations.

When it drops out, what messages are in the output of dmesg? Without this
information, we cannot help. What does “changing power state” have to do with
this? It is in your subject line, but not described any further.

Please be careful with the subject. Yours says BCM4321, but the computer output
says BCM4311. Those two are very different devices.

The HP site says BCM4321, yet Linux recognized it as BCM4311 or wrote it as such. I was puzzled at that as well.

If the modprobe works then I’ll be good to go - thanks, will try that next time it comes down.

I can assure you that the kernel does not read the HP web site. It relies on the
PCI ID codes, and 14e4:4311 is a BCM4311, not a BCM4321.
