In the UK, if you use a BT ADSL (or from supplier that resells BT
services) *and* the service is supplied with an ADSL modem, you *must*
use that device as a condition of the contract or BT may just
disconnect you and you still have to pay the whole contract. If you
buy the same service 'wires-only' you can connect any suitable device
of your own so I would check the small print before replacing an ISP
supplied modem/router. I am *not* making this up :-) it is just BT
weirdness.
Steve (who bought his service 'wires-only').
