Why My HP Router is Not Compatible with HP Laptop

Is anyone familiar with HP MSR920 Ethernet Router .I've got an HP XE3 laptop running W2K that I've managed to connect to the Internet (cable broadband). I can get to my homepage, but something goes wrong at that point and I can't get to any other web page (I get an "unknown address" message). I'm assuming there's some sort of compatibility problem between the router hardware/software and the HP BIOS, but it's just a wild guess. Thanks for any help.
