So I recently bout the TP-Link Powerline Ethernet Adapter Starter Kit from Amazon so I can get internet to the shop in my backyard.   I tested the unti inside my home and it worked perfectly even on different circuits within the house.   So my shop has a separate sub panel that's fed off the main panel with a circuit breaker.  Same Service in from the power company.   Now I cannot get internet with this out at my shop.  I have pair the units multiple times.   connected my laptop to the unit in the shop same as I did in the house and connects without internet.   I also tried a wifi router I had in the house and in the shop and connects to that but no internet at the shop.

What should I test here or what different product should I look into getting?
