After relocating the PLM and the Access Points a few times, I was able to get reasonably steady communications with the Xeonon's TURNED OFF. Whe I turned them back on, the problems re-appeared. I guess my next step is to install Leviton filters between the Xenons and the ToggleLinc. Does that sound like the best advice?

I am getting a steady report of links from the PLM links table, so this reaffirms that my problems probably emanate from the Xenon transformers and not from a bad PLM. Thanks for this advice! BTW, I was getting the same links report with the Xenons both on or off.

Might be a good idea to move this to the Insteon Communications forum. Sorry I started this in the wrong place.
