I bought a long-distance router for my parents business. They're trying to go from one building to another building that is close by. The new long-distance router seems to output a strong enough signal to show up with 5 full bars on my Macbook from the building that needs the signal, but it times out when I try to connect. When I'm closer to the router, it connects perfectly. All signs point to signal interference, which makes sense. I don't know enough about wifi to know what the next step is though. What I'm guessing is that the router is putting out a strong enough signal, but the macbook is unable to 'talk back' to the router. The communication must go both ways, right? When I connect to the network and then walk into the 2nd building, it stays connected, but when I try to load a website it won't load. It doesn't return an error, it just isn't receiving the page data from the router. Any advice? Do I need a repeater that is able to 'talk back' to the router?
