Basic Setup

In a WiFi network, computers with appropriate network cards  can connect wirelessly to a proper router. This router is usually connected to the Internet by means of a modem , often one featuring a high-speed connection. Any user within 200 feet or so (about 61 meters) of the access point  can then connect to the Internet, though for good transfer rates, distances of 100 feet (around 30.5 meters) or less are often suggested. Retailers also sell signal boosters that extend the range of a wireless network.
