Proprietary BCM wireless driver ceased to work

  • 772

Suddenly, the propriety Broadcom STA wireless driver ceased to work on my Inspiron 1525 Dell. All of a sudden, when I turned on the laptop the tooltip of the wireless indicator in the top panel shows networking disabled.

This also cause the wired network interface not to work, unless I manually dhclient it.

Indeed, lsmod doesn't show anything with bcm in it.

How can I further troubleshoot the issue?

    Look at the file /var/lib/NetworkManager/NetworkManager.state. Very likely the attribute NetworkingEnabled or WirelessEnabled is set to false.

    Make sure the two lines show

    NetworkingEnabled=true
WirelessEnabled=true

    save the file and the restart the network-manager daemon with

    sudo stop network-manager
sudo start network-manager

    After this your network should come up again.
