I currently have Sky broadband with a wired connection to my Sky+ box. If I switch to BT broadband do I keep my Sky router or do BT send me their router? If so, how do I connect it to my Sky box?
Thanks in advance for any advice offered.

BT will send a router. You can use the same cable as before.

BT will send you a router. You can connect your ethernet cable from the sky+ box into the new router.

Thanks for the replies. Very helpful.

I recently got a new hub and since then my Sky+HD box connection has been almost nonexistent. I would be very grateful for any ideas how to improve it.
