If your PC's IP address starts with 256 then there is no way that you will be able to connect directly to the router on 192.168.1.1. You will most likely need to manually configure the PC's network address details to something like 192.168.1.2, netmask 255.255.255.0, gateway 192.168.1.1 or something like that and then connect to the router in order to access the configuration console. Once you have set the router up you can change your network details back to dynamic so that your PC will get IP address details dynamically from the router's DHCP server. I would expect this basic setup information to be provided by BT and/or UTV.
