131[blank_start]WEP[blank_end] (Wired Equivalent Privacy) is no longer considered secure because the key used for encryption is static (it doesn’t change).
- AWEP
132[blank_start]WPA (Wi-Fi Protected Access)[blank_end] is stronger than WEP and was designed to replace it. It typically uses TKIP (Temporal Key Integrity Protocol, pronounced tee-kip) for encryption. TKIP generates a different key for every transmission; however, the encryption algorithm used for its calculations is no longer considered secure.

133What is a Service Set Identifier (SSID)?
- AThe name of a wireless access point and wireless network.
- BIt is the identifying number for your wireless connection.
- CIt is a type of IP address.
- DIt is similar to a MAC address.
134If your computer supports 802.11ac, you would want to select the SSID for the 5-GHz band in order to get the faster speeds of the 802.11ac standard. If you selected the SSID for the 2.4-GHz band, the connection would revert to the slower 802.11n standard.

135For most networks, you can allow auto channel selection so the device scans for the least busy channel. However, if you are trying to solve a problem with interference from a nearby wireless network, you can manually set each network to a different channel and make the channels far apart to reduce interference.

139Wi-Fi Protected Setup ([blank_start]WPS[blank_end]), which is designed to make it easier for users to connect their computers to a wireless network when a hard-to-remember SSID and security key are used. It generates the SSID and security key using a random string of hard-to-guess letters and numbers.
