Do a new clean install and then your best off going around and installing the software yourself for the modem and you can see whats going on.
You could check the settings in Internet Explorer (Tools > Internet Options > Connections)
Yah all that seems good - and was confirmed as correct via Tiscli techy help guys.
I have the modem and the software here with me, and it seems I can check if it works via my BT broadband and the modem - as I have the same problem with it; connects but doesnt display the page.
Solved.
I did a full format and reboot of windows (as opposed to using the in-cd restore utility which is rubbish) and all seems to be well.
Three hours updating to SP2 and everything thats needed before and after that. lol
