Ive had a problem with BT Broadband for a couple of weeks now, where i keep getting disconnected randomly! Although mine is just an external modem not a router! Tried loads of things and nothing seemed to resolve it, then on the advice from someone who works for BT i reset the modem 3 times by disconnecting the power from it!! Computers been on for the best part of 2 days now without any problems!! Might be of help....
