Attempted pairing (2) PA-8010 & (2) PA-9020, only communicating with their mates.
So this is my first foray into powerline adapters, so please forgive any novice ignorance...
For purposes of where I wanted adapters, my needs for multi-outputs in certain spots, etc. I felt like I did my research and bought two kits of two each, PA 8010s (AV1200) and PA 9020s (AV2000). I've had my 8010s for a couple days and loving them, but today I recieved by 9020s and they don't appear to be communicating with each other at all. The 8010s work fine together and the 9020s work fine together. I went back and double-checked that they're both AV2 architecture and should be working together. I tried pairing them on the same line, plugs 2' apart, and nada...red light on the powerline indicator of opposite types, where the same type connects immediately. Can anyone help me figure out what I'm missing and why they're not communicating? Thanks!
