It renders my laptop unable to re-establish the connection as it refuses to renew the IP address. Even if I dis-connect the phone.
The only solution is to disconnect the phone, re-start my laptop and reset the router. Nothing less will work.
As you can imagine.... it a pain in the privates.... Any idea just what is going on.
The only thing that comes to mind is that a few months ago I had a play with the settings to try and enable me to use the phone as a modem. I never succeeded, but have I knacked something in the process ?
