WPA and WPA2
WPA (Wi-Fi Protected Access) and its successor WPA2 are considered to
be the most reliable security options. WPA encryption uses the Temporal
Key Integrity Protocol (TKIP) while WPA2 encryption follows the Advanced
Encryption Standard (AES). AES offers a higher level of security and is
approved for sensitive corporate and government data transmission.
WPA and WPA2 authentication require a pass phrase. Each device on your
wireless network has to be manually configured with the same pass phrase
as the Ericsson W20. The encryption master key is derived from the pass
phrase and the network name (SSID) of the device.

authentication method.
If you have selected WEP 64-bit or WEP 128-bit, type the key for
encryption in the Pass
phrase / Key field. A 64-bit data encryption key
includes 10 characters. A 128-bit data encryption key includes 26
characters. Only the hexadecimal numbers 0 to 9 and letters A to F are
allowed.
If you have selected WPA or WPA2, type the pass phrase for
authentication and encryption in the Pass
phrase / Key field. A WPA or
WPA2 pass phrase is case sensitive and consists of between 8 and 63
characters. For security reasons, you are recommended to use a pass
phrase that contains at least 20 characters.
