802.11b/g supports two types of WEP security services: Open System and Shared key. Under open system
authentication, any wireless station can connect to the Motorola Cellular Gateway NC800 provided that it knows
the SSID of the Motorola Cellular Gateway NC800. If the Motorola Cellular Gateway NC800 is broadcasting this
information, then any wireless client can access the Motorola Cellular Gateway NC800. Under Shared Key the
Motorola Cellular Gateway NC800 generates a random 128-bit challenge. The station returns the challenge,
encrypted with a shared key—a "secret" key configured into both the station and the Motorola Cellular Gateway
NC800. The Motorola Cellular Gateway NC800 decrypts the challenge, using a CRC to verify its integrity. If the
decrypted frame matches the original challenge, the station is considered authentic. The challenge/response
handshake is repeated in the opposite direction for mutual authentication.
WEP data encryption is a weaker encryption method than that used by WPA-PSK. Either 64-bit or 128-bit keys
can be specified. If either WEP Data Encryption or Shared-Key Authentication is required, one or more WEP
encryption keys must be provided. Note that WEP data encryption can be provided even if shared-key
authentication is not required and vice versa.

• Authentication. - Selects the WEP authentication method.
o Open – all stations are granted access. The default value is Open.
o Shared Key – stations possessing the WEP key are allowed access.
o 802.1X – 802.1X is used to perform authentication using a RADIUS server and WEP key
o Shared Key – stations possessing the WEP key are allowed access.
o 802.1X – 802.1X is used to perform authentication using a RADIUS server and WEP key
distribution.
Warning: 802.1x Authentication method requires RADIUS server configuration.
