It require BT Broadband to work and the line possibly needs something activating at the DSLAM to enable the router to work.
The best advice is to contact BT.
Yup got all that, they foned up wiv the details etc and they also sent the BT Homehub with the broadband package an I've been tryin to sort it out but no luck lol.
Its definately different to how the other broadband routers work.
I've used an set up a Belkins, Netgear and wanadoo (orange "livebox") router before with no problems at all but this BT ones just complicated.
Its ok tho i'll just leave them to use the old router, i thought i would just bring it up to see if any one else is having problems with it.
