    This is your wireless device

    I take it you ran the offer of addition drivers that would probably have been offered for you?
    Your device should work perfectly and it looks like the proprietary broadcom driver is in place.
    Don't you see any access points offered?
    Is your system fully updated? (Have you rebooted)

    FYI: I have a very similar device but I don't use the driver Ubuntu throws at you. But that's just me. And what you have should work.

    Re: having wifi issues

    yes I installed the driver that was suggested and I also rebooted. I will try to reboot again and see what i can do. I know I have wifi available because I am connected to it with another laptop. I really appreciate you looking thorough all that! at least now I know nothing is terribly wrong lol

    Please copy and paste this with your mouse in to a terminal

    Code:
    echo -e "blacklist bcm43xx\nblacklist b43\nblacklist b43legacy\nblacklist ssb" | sudo tee -a /etc/modprobe.d/blacklist
    see if it helps

    Re: having wifi issues

    Open up a terminal and run

    Code:
    ifconfig
    Does wlan0 show up? If not, run this

    Code:
    ifconfig wlan0 up
    then run this one again

    Code:
    ifconfig
    and see if wlan0 shows up.

    As a side note, have you checked to make sure the "enable wireless" checkbox is checked in the network manager?
