including 802.11b (11 Mbps using the 2.4 GHz spectrum), 802.11a (54 Mbps using the 5 GHz spectrum), 802.11g (54 Mbps using the 2.4 GHz spectrum), and 802.11n (300 Mbps using the 2.4 GHz spectrum, the 5 GHz spectrum, or both)this term identifies a specific wireless LAN. To connect to a network, a device must "know" the SSID of the network.Wi-Fi Protected Access (WPA): An improvement to WEP, WPA addsamong other changesa key (TKIP, or Temporal Key Integrity Protocol) that changes dynamically over time, which eliminates the greatest shortcoming of WEP. WPA is the minimum level of security you should choose, if at all possible. WPA-Enterprise adds 802.1x authentication to make the network even more secure.Wi-Fi Protected Access 2 (WPA2): WPA2 adds even further enhancements to WPA, including AES (Advanced Encryption Standard), which makes the encryption key almost impervious to current cracker attacks.Wired Equivalent Privacy (WEP): The encryption system used by wireless LANs to provide security on the network. WEP uses an encryption key (which can be 40 or 104 bits longthese keys are often referred to as 64- and 128-bit keys because of some extra bits used in the WEP system) to encrypt data flowing across the network. Without the WEP encryption key, unauthorized users see only garbled data and cannot read what is being sent across the network.
