I am setting up a wireless network for a company with about 30 Macs. I usually use Cisco Access points but they are a little out of their price range. I don't have much experience with Apple's wireless products but I have a little. I'm not sure I would go with a TimeCapsule because I set one up and after a few months it became very slow. I think it couldn't handle the TimeMachine backups and the wireless at the ame time and that was for a network with only 6 Macs on it. I turned off the wirless and got an AirPort Express. It is working fine but I'm curious if anyone has setup a larger network with them. I have two buildings that need to be covered and am probably looking at two access points per building. The buildings are connected via fiber.
