this is the router they / I use

before this there is a black box on the wall inside your house which converts the fibre to ethernet and then this is connected to the router.. somehow the router knows or has a username and password to be able to connect the user account and provision the correct package, you'd think you would be able to just use any cable router like you would with virgin but without the user detail's you simply can't.
there is a draytek (think that's how it's spelt) that will work with some reconfiguring but by all accounts it's a pita to do
oh the customer service is very dire, i've had experience with virgins army of drones and their not a patch on vodafone's muppets
