Netgear Wireless router and BT Broadband

[Hamrah]

I've come unstuck with this one.

I'm setting up a wireless network for a colleague, and want to install a Netgear wireless router for him.

Never having dealt with BT before, I'm struggling with the " user-name" and password elements of the setup. I understand BT Broadband doesn't use passwords, so what are the correct inputs into the Router Setup, to make it talk to the BT account?

Any help much appreciated.
