If you buy your own modem you will not get any support what so ever from virgin, but thread above gives recommended modems, ensure you get a 50mb compatible modem as there is a big upgrade comming soon..
Read the thread ive linked above,,
The thread was written at a time when they were not even offering 20mb let alone 50mb.
Does anybody know the Netgear one they supply ?
