Dave, since the TIU is working with your remote, we can assume that problem is the Wi-Fi. Either, or maybe both, H1000 or GRJ might be right. Since you live in a Mac world, can you download a Windows emulator? That would allow you to communicate with the Wi-Fi and update the firmware. Alternatively, take it back to your MTH tech, tell him the problem, and have him check the firmware and USB port.
