    Default Help with BCM 4312 Wireless

    Just upgraded to 11.4 from 11.3 and am having an issue getting the wireless working. I read through a couple posts and believe this is the relevant info:

    Linux linux-jy1p.site 2.6.37.1-1.2-desktop #1 SMP PREEMPT 2011-02-21 10:34:10 +0100 x86_64 x86_64 x86_64 GNU/Linux
    lspci -nnk
    0c:00.0 Network controller [0280]: Broadcom Corporation BCM4312 802.11b/g LP-PHY [14e4:4315] (rev 01)
    Subsystem: Dell Wireless 1395 WLAN Mini-Card [1028:000b]
    Kernel driver in use: wl
    I removed the brcm80211 driver and installed the b43 driver which didn't work (continually prompted me for my wireless password despite it being correct). Then I installed the wl drivers from packman but lspci -nnk kept showing b43 drivers. I didn't have a 50-broadcom-wl-blacklist.conf in /etc/modprobe.d/ so I created one with:

    # modules blacklisted for broadcom-wl
    blacklist bcm43xx
    blacklist ssb
    blacklist b43
    blacklist ndiswrapper
    Any idea why ssb still shows up in "hwinfo --wlan" despite being blacklisted? I tried rmmod'ing it but it was being used by the b44 module. I tried rmmoding b44 and then ssb and then my wired connection seemed to be gone from knetworkmanager so I added them both back and now that seems normal.

    Anyway, now with the "wl" drivers installed I can't find any wireless connections. I've been messing around with the wireless switch but no dice. Any suggestions?

    Can't believe I missed that... Anyway it's installed now but I have another issue. "hwinfo --wlan" now produces no output while "/sbin/lspci -nnk" now says the driver in use is: b43-pci-bridge instead of wl. I tried running "/sbin/modproobe -rv b43" followed by "/sbin/modprobe -v wl" and rebooting but it still shows b43-pci-bridge.

    You used su or sudo on those modprobe?

    Do you have a file: 50-broadcom-wl-blacklist.conf
    at: /etc/modprobe.d

    Showing

    # modules blacklisted for broadcom-wl
    blacklist bcm43xx
    blacklist ssb
    blacklist b43
    blacklist ndiswrapper

    I've also had to blacklist acer-wmi on my Lenovo S12 to get my wireless to connect automatically, and reconnect after hibernation or standby. You may also want to install rfkill.
    I'm confused...No, wait...Maybe I'm not...

    Yes I su'ed before and my 50-broadcom-wl-blacklist.conf has the same contents. knetworkmanager doesn't seem to be seeing the card anymore, wireless options don't pop up when selecting the system tray icon. Neither wired or wireless appear there. They do show up (without any signal strength) when I select "manage connections..." though. Whast does rfkill do?

    Ok rfkill says dell-wifi is neither soft or hard blocked.

    Done. hwinfo --wlan still produces no output, and b43-pci-bridge still shows as the driver for /sbin/lspci -nnk
