Replacing USB Modem with Wireless Modem Router

[Makosss]

I'd be really appreciaive if someone can help me solve what is probably a simple problem to the initiated...

I've bought a BT Voyager 2100 ADSL modem router and need to use it to replace my Speedtouch USB Modem. Problem is I can't even get the BT Configuration Manager to appear (as per the simple(!) instructions). Typing 192.168.1.1 in Explorer doesn't help - I just get Page Not Found.

Can anyone help me in this? Many thanks...

Although my ISP for my router is that. Are you sure that is yours? Is it lighting up correctly to match your network settings?

Discovered the problem which was that I needed to set the IP address to configure automatically... How was I meant to know that!?
