Who is your internet provider? Mine is BT Yahoo and the network name required was not what I thought. When I set up my router/modem, I had to phone BT Broadband tech support to find out the correct network name. In my case all was fine but BT wouldnt let me connect because I had failed to provide the correct network name. Once I typed it into the set up box everything worked.
By the way try not to type in block capitals.
