Same exact issue here with 2 adapters. Both worked well for a long time, then suddenly could not connect to either one. Adapter shows up on TV and my Microsoft Surface Pro3. Message on Surface is "connecting." Message on TV is "connecting to Bill's device." Then, "unable to connect." Tried connecting two adapters connected to two TVs using three Surface Pro devices. Same result.
