    WPA Broadcom 4306 Issues


    Hello, I just did a fresh install of Ubuntu 9.04 on my laptop and cannot get my Broadcom BCM4306 to work with a WPA encrypted network. The wifi works fine on unencrypted networks, however my primary network is WPA encrypted so i need help solving this issue.

    Here are the details of my configuration via a script provided on this forum:

    It looks like you have the Broadcom firmware installed, so that's not a problem.

    What method are you using to handle the connections? Are you using a connection manager, like NetworkManager or Wicd? Or are you connecting using terminal command iwconfig? Or some other way?

    Install the Wicd connection manager, and see if that works better. Use Synaptic to install it, and it will uninstall the default NetworkManager.

    You will need a wired connection, or a wireless connection.

    waterhead, worked perfectly with the substitution of wicd, thanks a lot!

    not sure why ubuntus built in network manager couldnt handle it but this new one works great.

    There seems to be some bugs in the current version of NetworkManager. It has worked flawlessly for me in previous versions, so let's hope they work things out.
