I have had a laptop on dialup for years and decided I needed broadband so I rushed out and made a few purchases before I looked into it fully. I have since started reading a bit of info on the net and think I need a bit more advice before I make any more blunders. (Possibly to late!!)
I agree with the advice so far, just use the TG585 provided by Telecom and return the WRT160N (if possible) as you don't really need it.
What plan with Telecom have you signed up for?
