    Unreliable Broadcom BCM43224 wireless

    Hi

    I'm having all sorts of problems with my wireless connections in an HP Pavilion DM1. I'm sure it was working last week...

    I have two access points, one with WPA, one unsecured. It's not working with either. I can connect to both of them fine with a wifi USB adapter.

    I've tried:

    • Using Wicd instead of networkmanager
    • Using the proprietary driver
    • Installing the linux-firmware package from Oneric (version 1.54)
    • Changing the frequencies the AP runs on


    I haven't tried ndiswrapper yet.

    I used to use this with Lucid, with no problems (except I had to use wicd with it).

    Does anyone have any other suggetions?

    The relevant "lspci -v" follows:

    Code:
    02:00.0 Network controller: Broadcom Corporation BCM43224 802.11a/b/g/n (rev 01)
    	Subsystem: Hewlett-Packard Company Device 1510
    	Flags: bus master, fast devsel, latency 0, IRQ 16
    	Memory at 93500000 (64-bit, non-prefetchable) [size=16K]
    	Capabilities: <access denied>
    	Kernel driver in use: brcm80211
    	Kernel modules: brcm80211
    and part of /var/log/syslog, while connecting to the unsecured AP (I hope it's the relevant bit):

    Code:

    Re: Unreliable Broadcom BCM43224 wireless

    i have had similar problems, and reinstalling the b43 drivers seems too have fixed it:
    step 1: download these two things from here:http://downloads.openwrt.org/sources...a-3.130.20.0.o and http://mirror2.openwrt.org/sources/b...0.10.5.tar.bz2
    step 2: extract the second one to your home folder, and copy the other one their too
    step 3: download b43-fwcutter from the software center
    step 4: execute these steps too get it working:

    ~$ sudo b43-fwcutter -w /lib/firmware wl_apsta-3.130.20.0.o
    ~$ sudo b43-fwcutter --unsupported -w /lib/firmware broadcom-wl-4.150.10.5/driver/wl_apsta_mimo.o

    I'll give that a shot tonight. I notice though that it seems to be using the "brcm80211" driver, not b43 (perhaps they're the same?), so perhaps that's the problem.

    Re: Unreliable Broadcom BCM43224 wireless

    It seems to be working... for now. I used the restricted driver:

    1. Install the restricted driver via System/Administration/Additional drivers
    2. Add to /etc/modprobe.d/broadcom-sta-common.conf:
      Code:
      blacklist brcm80211
    3. Update the initramfs:
      Code:
      # update-initramfs -u -k $(uname -r)
    4. Reboot


    I restarted, then "iwconfig" showed the network card under a different device. Last time I didn't add the blacklist line, nor did I update the initramfs.

    Somewhere along the line I also installed the firmwares from oneiric.

    As a bonus, the wireless light turns blue again when it's enabled!

    Part of the instructions came from the Debian wiki.
