So you run a connection from your PC to your broadband modem/router, then to the provider?

If so;

The limited or no connectivity issue is between your modem/router and PC.

In NZ we had a similar problem, using a Telecom modem/router and XP SP2, due to dodgy Telecom firmware they borged onto a D-link.

You shouldn't have to use any drivers or software to connect to it, or the net. If you can, reset the modem, turn off DCHP, manually set an IP, and see what happens then.


WARNING - DO NOT DO IF YOUR ISP REQUIRES SPECIAL SOFTWARE IN THE MODEM/ROUTER TO CONNECT

If you have an ISP similar to that one here, you may want to see about flashing the modem/router with the manufacturers BIOS, making sure if DHCP is set you use DHCP on your PC, or use a static IP in both.

This fixed it everytime here.
