My company has 2 offices in 2 nearby buildings, the buildings are only about 20 or 30 meters apart, and each office has it's own working computer network (wired 10/100 with switch/hub). Because of some reason, the 2 buildings can't be connected via cable, meaning the only alternative is via wireless connection. Can anyone here tell me how to connect those 2 networks wirelessly? Is it possible to connect them using only 2 wireless LAN card installed in one of the computers in each networks? Converting every computers to wireless LAN is not an option because it will be too expensive. Any comment or advice will be greatly appreciated.
