I just moved into a new house and the previous owner had a media server and a pbx setup in a storage cabinet on the 1st floor.He told us the house is all wired for networking and TV in all the rooms on 1st floor. The fibre ONT is in the garage and in the living room on 1st floor the modem/router is connected with a ethernet wire to a socket in the wall(which I assume is connected to the ONT in the garage).
I have zero knowledge about networking and cabling so I am attaching the pics.I assume the white wire is for the phone(it is only working in one of the rooms which is all we want the telco guy connected it) and the red and blue are ethernet?What are those small blue plastic bulbs on the ends of the wire?
I want to share files over LAN/media server and get ethernet ineternet on the 1st floor.From what I have read online I need to terminate the ethernet connections into a gigabit port and bring my modem/router upstairs(I hope there is a wire coming from the ONT upstairs to do that) ? https://imgur.com/a/Xy6Sx
