Broadcom wireless 14.04 - 4.4 kernel

[nvidiot2]

Hi everyone,

I've got a Broadcom wireless card that I can't seem to get working.

iwconfig does not show the adapter. When I type 'sudo modprobe wl' I get the following errors in dmesg

[ 2869.159430] wl: Unknown symbol cfg80211_inform_bss_frame_data (err 0)

I've reinstalled bcmwl-kernel-source several times, even trying more recent versions. They all give the same errors in dmesg.
Tested versions (aside from the one that apt installs by default)

bcmwl-kernel-source_6.30.223.248+bdcom-0ubuntu11_amd64.deb

The 248 driver is too old and buggy, try a newer one:

sudo apt-get remove --purge bcmwl-kernel-source
sudo apt-get install linux-headers-$(uname -r) build-essential dkms
wget http://de.archive.ubuntu.com/ubuntu/pool/multiverse/b/broadcom-sta/broadcom-sta-dkms_6.30.223.271-3_all.deb
sudo dpkg -i broadcom-sta-dkms_6.30.223.271-3_all.deb

[nvidiot2]

The broadcom-sta-dkms_6.30.223.271-3_all.deb driver gives the same errors
