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.
obviously the best solution is to run an ethernet cable.
if one has coax cable already could use that with moca adapters.
also because its indoors and if there is a clear line of site, you could use p2p wireless bridge look at mikrotik wire, you could get close to 1gbs speeds.
