    Both of the above are normal. What about the other two commands that caf4926
    asked about, or the blacklisting?

    What I am finding now is that if I boot up and have no wifi I can run the code to install the firmware and then of course the download fails but because it was already installed it installs, remembers my wifi router and password and connects me. Then next time I reboot or shut down I have to start again. For some reason it's losing the firmware after a reboot.

    It is NOT losing the firmware. The file that was downloaded was discarded, but
    the extracted files in /lib/firmware/b43/ are still there. If you don't believe
    me, then check.

    The reason that running the script gets you wireless is that the script ends
    with 'sudo /sbin/modprobe b43'. You can accomplish the same result by running
    that command, *OR* you can remove the blacklisting of b43 and/or ssb, which is
    probably in /etc/modprobe.d/50-blacklist.conf.

    I ran the other two commands and still I lose the wireless at reboot. I'm searching the /etc/modprobe.d/ directory and there is a file there called 50-blacklist.conf but searching the file there is no b43 or ssb listed there. Is there anywhere else that they might put that device if it was blacklisted?

    Those commands were not to get you wireless at boot, but to get you wireless
    after you boot.

    The blacklisting could be in any file in /etc/modprobe.d/.

    Run 'egrep "b43|ssb" /etc/modprobe.d/*' and report what shows up.

    After booting, did you check to see if 'sudo /sbin/modprobe b43' is enough to
    get you wifi?

    If the b43 module is present after you have booted
    Code:
    /sbin/lsmod|grep b43
    then your issue is not with the hardware, but with establishing a wireless connection.

    What does the following return?
    Code:
    /usr/sbin/iwconfig
    Are you using network manager to connect with? Or did you configure with YaST (traditional ifup method)?
