    Ubuntu 11.10 getting wireless BCM4311 working


    I have an Dell Vostro 1500 with a Broadcom BCM4311 wireless card. After installing Ubuntu 11.10, I find that my wireless doesn’t work. The reason, Ubuntu detects the wireless but then loads the incorrect driver for this card.


    I use the lspci command to display the details about my hardware. It will display all of your PCI connected hardware. I edited the output to show only the relevant information. The important information here for matching your hardware with mine is this indentifier [14e4:4312].
    $ sudo lspci -v

    30:00.0 Network controller: Broadcom Corporation BCM4311 802.11a/b/g (rev 01)
    Subsystem: Hewlett-Packard Company Broadcom 802.11a/b/g WLAN
    Flags: bus master, fast devsel, latency 0, IRQ 18
    Memory at c8000000 (32-bit, non-prefetchable) [size=16K]
    Capabilities: [40] Power Management version 2
    Capabilities: [58] MSI: Enable- Count=1/1 Maskable- 64bit-
    Capabilities: [d0] Express Legacy Endpoint, MSI 00
    Capabilities: [100] Advanced Error Reporting
    Capabilities: [13c] Virtual Channel
    Kernel driver in use: b43-pci-bridge
    Kernel modules: ssb

    $ sudo lspci -nn
    30:00.0 Network controller [0280]: Broadcom Corporation BCM4311 802.11a/b/g [14e4:4312] (rev 01)




    The Solution
    I am going to install the correct driver for this wireless card. Then I will remove the “incorrect” driver (bcmwl) which Ubuntu installed by default.
    $ sudo apt-get update
    $ sudo apt-get install firmware-b43-installer
    $ sudo apt-get remove bcmwl-kernel-source
    $ sudo reboot




    Hopefully you found this useful.
