122 Version 1.0
Note: 128 bits WEP is most secure, but has more encryption/decryption overhead. Note that all wireless
devices must support the same WEP encryption bit size and have the same key. Four keys can be
entered here, but only one key can be selected at a time. The keys can be entered in ASCII or
Hexadecimal. Select the item from drop-down list you wish to use.
Pass phrase: Automatically generate four WEP keys. A WEP key is either 10 or 26
hexadecimal digits (0~9, a~f, and A~F) based on whether you select 64 bit or 128 bit in
the WEP drop-down menu. Type a combination of up to 64 letters, numbers, or symbols
in the blank, MT4205 uses an algorithm to generate four WEP keys for encryption. If you
want to type in the keys manually, leave this field blank.
Note: This function eases users from having to remember their passwords. But this isn’t as secure as
manual assignment.
WEP Key: At most four keys can be set. A WEP key is either 10 or 26 hexadecimal
digits (0~9, a~f, and A~F) based on whether you select 64 bit or 128 bit in the WEP
drop-down list. MT4205 must have at least the same default key.
12. Encrypt Type - WPA
The WPA encrypts each frame transmitted from the radio using the pre-shared key (PSK)
which entered from this panel or a key got dynamically through 802.1x.
WPA-PSK (TKSP): Allow the access from WPA clients simultaneously and the
encryption keys are given from PSK respectively.
WPA Rekey Timer: Allows for the session keys to be refreshed over time,
minimizing the amount of data that is encrypted with the same session key.
ASKII: The 8~63 ASCII characters can be entered, for example,
―0123456789ABCD….‖
