turn everything off
connect a rj-45 cable between 'wan' port on router & the modem
connect a rj-45 cable between one of the 'lan' ports on the router & the network card in your pc
turn on the modem, leave it for at least 30 second to stabilise - 'synch' and 'ready' lights should be lit.
turn on the router, and again let it stabilise, you should get lights corresponding to a WAN link
finally, turn on the computer, which 'should' initialise your connection ??
- 'connection' after that is a function of which browser to choose to use, I'm not going there ...
