I have a customer who would like to setup wireless across two buildings. We've tried a couple of things, including a large directional dish which improved the signal dramatically... But it still isn't good enough. I have seen signal boosters, but they often say "for use only with blah brand router" etc... Can boosters be used with ANY wireless router? Or do they have to be manufacturer specific? I cannot find a booster specific to this model router. I have also been told that access points can act as signal boosters, but I've yet to get this idea to work. Is this possible? I've tried playing with options etc.. My thought was to add a signal booster near a window and be done with it, but I can't find a signal booster? Then I was told I could use an access point as a signal booster, but I do not see how. The current sitaution is there is a building at the bottom of a hill (router / access point location). There is also a building at the top of the hill (Signal must reach here). The signal reaches through the windows and certain parts of the buildling, but is extremely poor quality and spotty at best.
