Let's poke it a little:

sudo modprobe b43
dmesg | grep b43
dmesg | grep 0c:00

Thanks.

Hi
I have a slightly different - if not weird - problem in helping out a mate with an Acer Aspire 5720 with a BCM4311 wireless device. The b43 module loads ok from either a basic install or using "apt-get install linux-firmware-nonfree" and it connects ok with a couple of wireless routers but will not complete a login with a ZTE MF66 broadband modem. It recognises the MF66 and attempts to connect but fails every time. Before you ask, the connection to the MF66 has been separately verified.
It seems like there is a compatibility issue between the device driver and the MF66 giving some sort of handshake issue.
No joy from dmesg.
Any clues for this one? Just about to revert to a usb device.

Please try this:

sudo apt-get remove --purge bcmwl-kernel-source
sudo apt-get install linux-firmware-nonfree

Reboot and let us have your report.

Hi Chili555,

That's impressive and simple to implement. But will it work for a similar problem on my new Toshiba Sat Pro C850 as well?

Or, do I need a slightly different (but similar) work around?

Please help.

Does your C850 have the exact, exact same device?

lspci -nn | grep 0280

Is it 14e4:4311? If so, then yes, indeed. If not, post the result in a new thread and I'll be happy to help.
