i'm using ubutnu 10.04. till recently i had no problem at all, but from a few days back i'm unable to connect to wireless network at all. i can see the wireless connections and when i select the network i want, it asks for authentication. but even after giving the correct password i'm not connecting to the network. all the network settings seems to be correct. i can access the network from windows but not from ubuntu. i am unable to decide what would be causing the problem. can anyone please suggest me on what could be the problem. thanks.
