Security Mode
WEP Key Length
default value if you don't know what it is, default value is 2346.
802.11 standard defines two mechanisms for authentication of
wireless LAN clients: Open Authentication and Shared Key
Authentication.
Choose one of the security modes from the drop down list. If
you choose OPEN or SHARED, you have to type WEP
information.
OPEN – Open authentication is basically null authentication
algorithm, which means that there is no verification of the user.
SHARED – It works similar to Open authentication with only
one major difference. If you choose OPEN with WEP
encryption key, the WEP keys is used to encrypt and decrypt the
data but not for authentication. In Shared key authentication,
WEP encryption will be used for authentication.
If you choose WPA-Personal or WPA2-Personal, the
corresponding WPA settings will be listed as follows. You have
to choose the WPA algorithms and type the pass phrase for such
security mode.
WPA Algorithms – Choose Temporal Key Integrity Protocol
(TKIP) or AES for data encryption.
Pass Phrase – Please type 8 to 63 alphanumerical characters
here.
WEP (Wired Equivalent Privacy) is a common encryption
mode. It is safe enough for home and personal use. However, if
you need higher level of security, please consider using WPA
encryption (see next section).
Some wireless clients do not support WPA, but support WEP.
Therefore WEP is still a good choice for you if you have such
kind of client in your network environment.
There are two types of WEP key length: 64-bit and 128-bit.
Using 128-bit is safer than 64-bit, but it will reduce some data
