Default Transmit Key

Sets which WEP key (1-4) to use when sending data.  Make sure the receiver is using the same key.

WEP Encryption

Once WEP enable is checked, choose 64-bit or 128-bit WEP encryption here.
Note: some access points do not support 128-bit encryption.

Passphrase

This is the code used when logging a wireless device onto the wireless network. The passphrase is case-sensitive and should not be longer than 16 alphanumeric characters. WEP key settings are based upon the passphrase created by you. This passphrase is compatible with Linksys wireless products only.
Note: In 64-bit, 4 different keys will be generated. In 128-bit, 1 single key will be generated for all 4 key fields.

WEP keys 1-4

Enables you to create an encryption scheme for wireless LAN transmissions. Manually enter a set of values for each key. 128-bit encryption requires more system resources than 64-bit encryption. Use 64-bit encryption for better performance.
If you are using 64-bit WEP encryption, then each key must consist of exactly 10 hexadecimal characters in length.
If you are using 128-bit WEP encryption, then each key must consist of exactly 26 hexadecimal characters in length.
Valid hexadecimal characters are "0" - "9" and "A" - "F". A WEP key field that is left blank is a key of all zeroes.
