By default the wireless security of this router will be disabled. In this
next option the user can enabled or disable wireless security for the
frequency band 2.4GHz. 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:

D-Link DIR-850L User Manual
Here the user can specify to either use a
64Bit or a 128Bit encrypted key.
Authentication is a process by which the
router verifies the identity of a network
device that is attempting to join the wire-
less network. There are two types authen-
tication for this device when using WEP.
Open System allows all wireless devices
to communicate with the router before
they are required to provide the encryp-
tion key needed to gain access to the
network. Shared Key requires any wire-
less 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.
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.
