Used in conjunction with a D-Link DIR-655, proved a complete doddle to set up and get going. Much like other D-Link products, used the included disc to quickly set it up and get it working within a matter of minutes and then fine-tuned it afterwards. Haven't had a single hitch, no dropped connections or other problems using BT Broadband. Connection is stable, quick and reliable unlike my old failing modem/router combo.
Can't recommend this highly enough. If you're after a stand alone modem to go with your stand alone router, this wont dissapoint.
