I have used the kit successfully to connect my deskttop and Smart TV to the router. Connection for a second Smart TV was patchy using its pre-installed WiFi connector, so you suggested adding a WPA863

I have this kit, which connects the router (Room 1) to my desktop (Room 2) and Smart TV (Room 3) I now have another Smart TV (JVC) in Room 4 and the inbuilt WiFi connection is intermittent at best. Th
