Had mine powered up for a few days (was working yesterday), BUT just now after I read your post, went to my unit showed and error code 5 and was not connected, would not restart, unplug the unit, powered up the unit, connected and then lost connection, reset the interface and unit connected to my network and appears to be working so far. Ill keep it going for awhile and see what happens. Ill keep you updated. What I just typed, will copy and send to Bryston, will also copy what you just mentioned and send that too if you would like. Funny that it's happening after updating to new firm ware, wonder if others experiencing this same issue.
