We use wireless at our school and the only problems that we have is moron users reloading their machines and not knowing how to set up the network for their machine. Other than that its great, we run on a T1 and average 100-200KBps on downloads with the CATV and the wireless average 120-200KBps. We are using linksys for the hubs and linksys with the cards. Just be sure that you dont put the access point right next to something that will cause interference such as central air unit, fridge, etc, really just any large appliances.
