Hi, I have two TL-WPA4220 AV600 Powerline Wi-Fi Extenders set up in my home, as there are two PC and PS5 set ups far away from the router. These have been working perfectly in tandem for over two years now. However recently, they seem to be interfering with each other. When only one is plugged in, the WiFi and Ethernet connection is perfect for one set up, but when both are plugged in, there is lots of lag, and speeds are considerably lower.

Is there a way to stop these two interfering with each other?
