I am hoping that someone out here can asssit with an IT question.
What I want to be able to do is to simply add more wired Ethernet lines to my existing network which is pictured below. I thought just adding a switch would do it but I was wrong.
The existing works just fine as it is with the exception of the Apple TV which does not work due to a WiFi being plugged into a WiFi I think. When I currently use the Apple I just temporarily will use the Xbox deed and then out it back to the way it was.
Can someone please advise how I can add more wired nodes to this setup and what I may need to buy to do this. Many thanks in advance
