I have a computer that has wifi 6E. I have a router that has wifi 6E. I have the computer attached via cat 6a cable to the router. When I start the computer, it connects to an SSID ending in 6G. it does the same when I also have the router connected to my Internet gateway via a cat 6a cable. All good here except I have wires running across entryways.

I am trying to use Powerline adapters to bring Internet to my router. When I connect the internet to the router via Powerline my computer boots up with an SSID that ends in 5G and isn’t one assigned to my 6E router. Oddly, it matches a router that used to be connected to my gateway and is now disconnected and turned off. Why?

My goal was to connect the internet and the PC to the router using Powerline adapters. When I tested the powerline adapters, I got around 200 mbps on outlets in same room and around 100 mbps on outlets in adjacent rooms. I was going to see if the internet connection would be adequate for my quest 3 PCVR gaming before I tried them for the PC connection. The quest3 doesn’t see the same SSID that the PC has when I use Powerline and so it can’t link to the PC. I don’t really want 5G anyway. When everything is hard wired, it works great. The PC and quest3 are both attached to the SSID ending in 6G.
