    [Problem] Unable to access wireless access point.

    First off, I am new to linux so I'm still a little "overwhelmed" by it all. I am trying to get my wireless network to work. Wired connection works just fine. I've tried every troubleshooting article I could find but nothing seems to work. So, here we go.

    I am currently running Ubuntu 8.04 on a HP Pavillion dv6000.
    My router is a Linksys WRT54G transmitting a 2.4GHz WPA-secure signal.

    if there is any other information you need, please let me know. I have already tried the "WifiDocs/Driver/bcm43xx/Feisty No-Fluff" document with no success. I love linux but I need the wireless connection.

    Also, manual configuration is an absolute last resort. I go to a university with several different access points and don't want to have to re-configure my wireless card each time.

    You could try installing WICD in place of Network Manager if you really want a GUI.
