If you have a wireless router or access point, you can set up your own wireless network. A router directs communication traffic between two networks, such as a home or office network and the Internet. An access point provides wireless access to a wired Ethernet network. An access point plugs into a wired router and sends out a wireless signal, which other wireless computer and devices use to connect to a wired network. During the set up process, you need to specify a network name, choose file and printer sharing options, and a passphrase (a security key) to provide secure access. If you have a USB flash drive, you can save wireless network settings to the drive and use it to quickly add computers to your network.
