Bt Voyager 2000 networking problems.

Hi.

I have a BT Voyager 2000 ADSL Router, which is constantly plugged in to both power supply and phone line.

The PC I am currently using is connecting to the router using a BT Voyager 1010 ADSL USB wireless adapter.

However, when I connect to the network, I often find myself either being disconnected from the internet, or sometimes even the network itself.
The disconnections can occur as rarely as once or twice a day, sometimes not at all, but usually I get at least 1 disconnection per hour.

I cannot access voyager.home even when I am connected to the network, could this be the cause of the problem? If so, how would I fix it.
I can find no entry in my hosts file that would make this url a valid resource.
The only lines i have are:
I have tried numerous times uninstalling and reinstalling the network onto the PC, but this doesnt fix the problem.

Any ideas as to how i could fix this problem?

...

I reset the router to it's factory settings (took me a while to find something small enough to put in the hole to get the reset button), and so far it hasnt disconnected from the network, but it still loses connection to the internet.

Any suggestions?
