I have just installed Ubuntu 8.04, and am working on getting wireless working. I followed a guide I found on this forum and now my card works with unsecured/wep networks. But, when I try to connect to a WPA network, I am always denied (I am using network manager). I have wpa_supplicant installed, and have seen some possible fixes floating around the forum but none really made sense to me... could someone please help me finish configure my wpa? Help is much appreciated!

Whenever I post something about this on any forum, I never get any response -- is this because this question is a bad one? sigh...

Sorry no one has answered your post. It's not a bad question but it probably isn't specific enough. You might have more success if you tell us what exactly happens when you try to log on with WPA. You can also do a search by putting the error message (if there is one) in the search window.

I use nm and WPA but am not the best person to try to troubleshoot it. There are several different flavors of WPA (WPA Personal, WPA2). You might want to open up Network via System, Admin, Network, Unlock and check the wireless settings. Make sure the network name is correct, you may need to enable roaming, and make sure the password is correct (sometimes my password seems to get doubled up).

Thanks for responding! Since I use network manager, I dont get any feedback on what went wrong -- all I get is network manager spinning around and then giving up. I am using WPA Personal with TKIP and have checked the settings,

give that a try and see if your broadcom card is supported
