    Question Dell E1505 with 12.04 LTS Wireless issues

    Using another post, I am going to show what the system gives me. It's a Dell Inspiron E1505, 2Gb RAM. I'm using the Verizon MiFi 2200 hooked to USB to connect right now. If I go to Windows Vista, I get into my home wireless network fine, but coming over to Ubuntu, not so much. So, here's what I did...
    lspci -nn | grep 0280
    shows:
    0b:00.0 Network controller [0280]: Broadcom Corporation BCM4311 802.11b/g WLAN [14e4:4311] (rev 01)
    And...
    lsmod | grep -e wl -e b43
    shows:
    wl 2646601 0
    lib80211 14040 1 wl
    And...
    rfkill list all
    shows:
    0: dell-wifi: Wireless LAN
    Soft blocked: no
    Hard blocked: no
    In Windows Vista, Fn-F2 turns on the Wireless (light). But, the light won't turn on, wireless won't work, etc. It looks like the driver is ok. So, is there anything additional I need to try/do?

    Thanks!

    Fn+F2 will turn on/off the wireless but there is no indicator to tell you whether it's on or off.

    Did you do this process yet?

    sudo apt-get update
    sudo apt-get install b43-fwcutter
    sudo apt-get install firmware-b43-installer

    I did those steps, wireless card still won't start.

    I saw the b43 reference in your first post and I thought you were using the same driver as I do, I also have a Dell E1505, but now I see you're using the Broadcom STA driver from the 'additional drivers'.

    Here's a thread that should get it working:

    Typing:

    sudo apt-get install --reinstall bcmwl-kernel-source

    gives Reinstallation of bcmwl-kernel-source is not possible, it cannot be downloaded

    Typing

    sudo modprobe wl

    gives no answer.

    Typing

    sudo modprobe -r wl
    sudo modprobe -r bcma
    sudo modprobe brcmsmac

    gives no answer.

    Typing

    sudo su
    echo "blacklist wl" >> /etc/modprobe.d/blacklist.conf
    echo "blacklist bcma" >> /etc/modprobe.d/blacklist.conf
    echo brcmsmac >> /etc/modules
    exit

    And rebooting gives NO wireless.

    lsmod | grep -e wl -e bcma -e brcmsmac

    gives

    Typing

    dmesg | grep -e brcm -e wlan
    iwconfig

    Gives

    lo no wireless extensions.
    eth1 no wireless extensions.


    Typing

    rfkill list all

    Shows

    Going into "Additional Drivers", the Broadcom one is listed, un-activated, but refuses to activate (I'm guessing that's the point). But, still no wireless (Fn-F2 will not turn on the wireless). Interestingly , 10.04 LTS worked fine with the wireless, did a full removal of the old one and installed 12.04 LTS on a cleaned partition.

    Any other ideas?

    I just spent the afternoon trying to resurrect an old E1505 that I have with Kubuntu 12.04. I had the same issues you described. After Googling a bit, I came up with something that worked -- hopefully it will work for you too.

    Code:
    sudo apt-get update
    
    sudo apt-get remove bcmwl-kernel-source
    
    # If the following file does not exist, don't sweat it.
    # However, you may need to comment out bcm43xx in /etc/modprobe.d/blacklist.conf
    sudo rm /etc/modprobe.d/blacklist-bcm43.conf
    
    sudo apt-get install b43-fwcutter
    
    After installing b43-fwcutter, make sure to REBOOT your PC!!
    
    Then run the following Terminal commands:
    
    sudo modprobe -r b43 b44 b43legacy ssb
    
    sudo modprobe b43
    
    Then RETEST wireless.
    Sure enough, when pressing Fn-F2, the WiFi LED lit up. All I had to do then was setup a connection to my router.

    But, I noticed that my wired-interface was no longer running; so I ran the following (note, I'm not certain whether the removal of b44 could have been deleted from the step performed earlier):
    Code:
    sudo modprobe b44
    To complete the exercise, reboot your system. Verify whether the wireless and the wired interfaces are both up/running.
    Code:
    /sbin/ifconfig
    If all is well, then disconnect your LAN cable and go wireless!
