The "WEP" tab
If an additional measure of security is desired on the wireless network, WEP (Wired
Equivalent Privacy) encryption can be enabled. Please select "Enable" in the above
screen, if you wish to activate encryption.
To activate WEP encryption, you will also need to select the "Key Length." You
may select either "64 Bits" or "128 Bits." Please choose the "Key Length" that is
the same as your Access Point.
Input 4 different "Key Settings" in the fields provided. For 64 Bits WEP encryption,
you may enter 5 characters in the range of "a-z", "A-Z" and "0-9" (for example:
MyKey); or a 10 digit hexadecimal value in the range "A-F", "a-f", and "0-9."(For
example: 11AA22BB33). For 128 Bits WEP encryption, you will enter 13
characters in the range of "a-z", "A-Z" and "0-9" (for example: MyKey12345678);
or 26 digit hexadecimal number for 128-bit encryption. If the number is entered
incorrectly the function will not work.
After entering the WEP keys, choose the WEP key you wish to use and click
"Apply" for the configuration to take effect.
