WEP. WEP is a basic encryption method, which is not as secure as the other two methods, Pre-Shared Key and
Pre-Shared Key + RADIUS. Select a level of WEP encryption, 40/64-bit, 128-bit, or 152-bit. If you want to use a
Passphrase, then enter it in the Passphrase field and click the Generate button. If you want to enter the WEP key
manually, then enter it in the WEP Key 1-4 field(s). To indicate which WEP key to use, select the appropriate TX
Key number.

Pre-Shared Key. This method offers two encryption methods, TKIP and AES, with dynamic encryption keys.
Select the type of encryption method you want to use, TKIP or AES. Enter the Passphrase, which can have 8 to 63
characters. Then enter the Key Renewal period, which instructs the Router how often it should change the
encryption keys.
Pre-Shared Key + RADIUS. This option features a Pre-Shared Key used in coordination with a RADIUS server
that uses either EAP-TLS or PEAP as its authentication method. (This should only be used when a RADIUS server
is connected to the Router.) First, select the type of encryption method you want to use, TKIP or AES. Enter the
RADIUS server’s IP address and port number, along with the authentication key shared by the Router and the
server. Last, enter the Key Renewal period, which instructs the Router how often it should change the encryption
keys.
WEP. WEP is a basic encryption method, which is not as secure as the other two methods, Pre-Shared Key and
Pre-Shared Key + RADIUS. Select a level of WEP encryption, 40/64-bit or 128-bit. If you want to use a
Passphrase, then enter it in the Passphrase field and click the Generate button. If you want to enter the WEP key
manually, then enter it in the WEP Key 1-4 field(s). To indicate which WEP key to use, select the appropriate TX
Key number.

wep (wired equivalent privacy): a method of
encrypting network data transmitted on a
wireless network for greater security.
IMPORTANT: If you are using WEP
encryption, always remember that each
device in your wireless network MUST use
the same WEP encryption method and
encryption key, or else your wireless network
will not function properly.
