Since no one has replied here I'll give it a try. At least you'll get a 'bump' anyway.
The transceiver boards becoming loose in the remote is a somewhat common problem. It can happen over time from the remote being jostled around. Which cord did you use for the remote to TIU tether? It MUST be the phone handset cord (curly one) for things to work properly. If your wifi unit (WIU) connects and works through to the TIU, I would think that would rule out any problems with your TIU, but the TIU also has a transceiver board so that could still be a possibility as well. Especially if you have recently handled (moved, etc.) the TIU, but this is possibly less common as the remote gets a lot more handling.
