Success at last. Phoned Tshiba and they said the problem I had was that I was not deleting the WEP set up. I was just adding a WPA connection and also trying by modifying the existing WEP connection. Where I was going wrong was I should have deleted all network connection, set up my HomeHub for TPA and then let the Toshiba find it automaticely. Took 2 minutes. Thanks BurrWalnut for your help and patience, sorry if I led you down the wrong Path.
