(SPV M1000) Problem with Internet access

Normally, when I Activesync with my PC via Bluetooth, I am able to share my desktop PC's ADSL connection on my SPV.

However, for the last couple of days, something's happened. I can still share the connection but now, when I disconnect Activesync, my PC's ADSL connection drops and I need to disable and enable the LAN network connection and all is well again.

It never did this before.

We have had some tremendous trouble with our ADSL connection lately (NTL) but all seems well now at least from our PC's point of view.

And I can still share my PC's connection on my SPV and everything still Activesyncs ok. It's just when I disconnect Activesync, the PC's net connection drops.

Anyone have any suggestions?
