Just came on to post a question about a similar thread.
Came home today and found that the laptop is not finding any webpages on our network. We have a desktop connected to the network which runs fine so it's just the laptop which has suddenly lost connection.
If i disconnect then try to reconnect I get the 'aquiring server address' stage, then it just stop and disappears. The utility which came with the modem says im connected to the network at 54.0 mbps and the strength is very low, but I cannot connect to the router to configure it.
So I cannot connect to the router but the PC is using it fine meaning that the router is obviously still getting the net and passing it on fine, it's just my laptop won't connect.
In my room I can pick up someone else's network which isn't protected and i've tried connecting to it and using it and it works fine... any idea whats up? The problem sounds similar to the one described above.
I'm on BT using the Voyager 2100 if it helps..
