I have lived in my current house for almost 16 years, but am now just setting up the pre-wired Ethernet. I have purchased a gigabit Ethernet switch, but am very confused as to what to do next. Here's a picture of the access panel. https://imgur.com/a/vvJz5. Any and all help would be appreciated, just trying to get my 85/87.5 up/down speeds to my new pc build upstairs!
