WEP 
WEP Key Length - 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. 
WEP Key Entry Method - 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 transfer performance. 
There are two types of key method: ASCII and Hex. When you 
select a key format, the number of characters of key will be 
displayed. For example, if you select 64-bit as key length, and 
Hex as key format, you’ll see the message at the right of Key 
Format is ‘Hex (10 characters) which means the length of 
WEP key is 10 characters. 
WEP Keys (Key 1 – Key 4) - Four keys can be entered here, 
but only one key can be selected at a time. The format of WEP 
Key is restricted to 5 ASCII characters or 10 hexadecimal 
values in 64-bit encryption level, or restricted to 13 ASCII 
characters or 26 hexadecimal values in 128-bit encryption 
level. The allowed content is the ASCII characters from 33(!) 
to 126(~) except '#' and ','. Such feature is available for WEP 
mode. 
Default Key – Choose one of the key settings.
