I live and work in a 5 story building. I have a wireless network set up on the 1st floor serving 5 computers. There are also two computers on the second floor being served by the wireless router on the first floor. The second floor signal strength isn't that good. I would also like to be able to access the wireless network from the 4th floor. The 4th floor signal strength is almost non-existant. Is it possible to use two repeaters, one on the second floor and one on the 4th floor to boost the signal strength througout the building?
