My WiFi was working for several months with the
network-manager in Ubuntu.
A couple of days ago, I tried to connect to an ad-hoc network. Afterwards I have not been able to connect to any wireless networks. I tried both
network-manager and command line tools.
Has anyone had this problem before, and has any idea what permanent configuration changes attempting to connect to an ad hoc network might cause?
iwlist scan works fine, and even
network-manager can see the wireless networks. I simply cannot connect anymore, and keep getting these messages from
