wrong connection status

I have an Averatec av3220h1-01 with XP home. I just installed sp2. Now the
connection status all the time shows that it is not connected when in fact
it is connected. The text under the security status states "The network
requires a network key. You are currently connected to this network. To
disconnect from this network, click Disconnect below." However on the task
bar the network icon shows it disconnected with a red x. What is the
problem?


Thanks.Peter
