In one rooom I have one PC with a router next to it. It’s connected via LAN. Then I have another PC in another room. The distance between a router and the 3nd pc (in a straight line) is about 6 meters. That room is on the adjacent wall. Up until now I’ve been using a Strong’s AP300 wifi repeater but I get high oscillations in download speeds and ping. Other than directly connecting my 2nd PC to the router via LAN, are there any other solutions you would recommend? Below is a drawing of how my situation looks like. I would try to avoid connecting it via cable as then i would have to drill through multiple walls.
