Same story here. I was about to go as far as the factory reset after finding the firmware update to V1.0.2.92_1.0.50 didn't work for me either. A factory reset will only reset with the most recent firmware, hence the issue likely remaining. Someone may want to try rolling back prior to 1.0.2.88 to see if NG broke the Matrix with that last major firmware update. They did improve the device list in that release...
