Section 3 - Configuration
By default the wireless security of this router will be disabled. In this next
option the user can enable or disable wireless security for the frequency
band 2.4 GHz. There are two types of encryption that can be used. WEP or
WPA/WPA2.
Wireless Security Mode: WEP
Wired Equivalent Privacy (WEP) is the most basic form of encryption that can
be used for wireless networks. Even though it is known as a 'weak' security
method, it is better than no security at all. Older wireless adapter sometimes
only supports WEP encryption and thus we still find this encryption method
used today.
The following parameters will be available for configuration:
WEP Key Length:
Here the user can specify to either use a 64 bit or a 128 bit
encrypted key.
Authentication: Authentication is a process by which the router
verifies the identity of a network device that is
attempting to join the wireless network. There are two
types authentication for this device when using WEP. Open
System allows all wireless devices to communicate with
the router before they are required to provide the
encryption key needed to gain access to the network.
Shared Key requires any wireless device attempting to
communicate with the router to provide the encryption
key needed to access the network before they are allowed
to communicate with the router.
WEP Key 1: Enter the WEP key used here. For 64 bit keys you must
enter 10 hex digits into each key box. For 128 bit keys you
must enter 26 hex digits into each key box. A hex digit is
either a number from 0 to 9 or a letter from A to F. You may
also enter any text string into a WEP key box, in which case
it will be converted into a hexadecimal key using the ASCII
values of the characters. A maximum of 5 text characters
can be entered for 64 bit keys, and a maximum of 13
characters for 128 bit keys.
