it be better if u tell us which model router u using
and you shouldn't be using any USB connections

does the NTL 250 modem have USB??

with the number 1 light,
i suspect u are saying the number 1 light on the router correct??
it only lights up if u have a ethernet cable connected to a working (turned on) network card or whatever

if u put more info here i would expect the more techie minded people will be able to help u
