Log in to the Modem/Router, in the Internet box, click Disconnect. This drops the PPP Internet session (this is not the sync), wait 30 seconds then click Connect. You usually end up of another Gateway. You can check which Gateway you are on. It should also ensure the relevant BT servers are updated with the current sync speeds.
It's would make PN think u have a fault on the line with reconnected to different gateway. I ain't bother as it make no different to which gateway.
