We have been with BT for several years now, and upgraded to Ultrafast about a month ago. Speeds are very good, but the volume of disconnects can be infuriating. I've found something of a work around for these in our situation which is to disconnect the faceplate at the master socket for a few seconds, and all the wiring from the hub, after which we can sometimes experience relatively interruption free broadband for 24 to 48 hours, then I have to repeat the process. Without doing this the hub will lose connection either briefly flashing yellow/orange 4 or 5 times per hour, or just disconnect completely and refuse to acknowledge any broadband connection giving us the middle finger purple light. There is very little on here that I could find in relation to the ultrafast service or hubs so I am wondering if anyone else is having similar problems and also if we are getting something akin to static build up on our line that could be causing this, or if a new hub might be recommended?
