Typical Internet Cafes have a combination of wired and wireless access. The wired access is typically a PC with a NIC card, using Ethernet cable of some flavor plugged into a smart switch or router (depending on the number of devices), which would then connect to a firewall. The internet connection would plug into the firewall as well. The wireless setup would be an antenna (access point)in place of a PC but is typically connected back to the same type of equipment. Cisco’s website has some really great diagrams to look at depending on the number of host you are trying to connect and what your trying to do with very specific breakdowns about the role of each device.
