I am having the same (or similar) problem. I installed Jaunty a couple days ago, and it had been working just fine with the internet wired into the computer. I decided to try my wireless connection, and the computer locked up. Now the only way to boot into Ubuntu without the computer locking up is to turn off my router (I think it has set the wireless as the prefered network or something). Then, when I turn my router back on, the computer freezes up again. I have reproduced this bug many times, and the only way to turn on my router without the computer freezing up is to disable wireless in network-manager. The home network is a WPA2 network and only has a single access point. Any help resolving this issue would be greatly appreciated.
