This is for a small client of mine situation: building 1 is a small office wired PCs and a cable modem for internet. Building 2 is a garage and has only 2 PCs which are networked no internet. Building 2 needs internet ONLY to update their internet based software periodically. The buildings are about 250 yards apart, building 2 is on a hill and is about 20ft higher then building 1, both buildings are in view of each other. Building 1 is a late 60s early 70s small brick building, building 2 is a steel garage. Is wireless from Building 1 to building 2 a solution? If so what hardware would be needed, I can figure out the price for the hardware. Or would it just be easier to go with another connection from the ISP? I would also need the best software package that would only allow certain domains or ip address to be accessed in building 2.
