As you discovered. Let's check discussions like this:
Yes, there is no solid always works answer. You must try the usual with directional antennas and wifi bridges.
Hi everyone, I'm not a pro at networking so I hoped you guys could help me out. I am currently living in a upper barn apartment that is next door to my landlord's house. My landlord and I have been trying to get internet connection into the house because they didn't bury ethernet cables when they were doing construction. The apartment is approximately 300 ft from the house and seperated by trees. Also, the apartment is made mostly of cement and metal on the outside. We have tried to get a wifi signal up there using Netgear N300 extenders but the signal speed is terrible (both because the distance required to travel, the blockage, and the adapter broadcasting and receiving at 2.4GHz). I was trying to come up with some other ways of solving this problem. The house and apartment are connected to the same powergrid so I thought about attempting to use the powerlines to broadcast the signal via powerline adapters but i'm not sure if I would need to hook that up inside the powerbox or not. Their house is older (ours is brand new) and so the wiring is different between both and I don't know if that will cause a problem. Additionally, burying a new ethernet cable is out of the option (and i believe the distance is too far). I looked at bridging it but i'm not familiar enough with that technology to know if it is cost effective/would work. Any help/advice anyone could offer would be highly beneficial.
