on your wireless adapters also supporting this feature. Different
manufacturers have developed different ways of converting plain text
and so interoperability is not guaranteed. If you are experiencing
difficulty, the Manual Hex Key method is supported by most vendors.
To set up WEP encryption:
1 Select 128 bit encryption or 40 bit/64 bit encryption from the WEP
Encryption Type drop-down list.
2 Select a key generation method from the drop down list. If you have
other wireless products choose the scheme that is compatible with these,
then enter the appropriate information. The key generation method can
be one of the following:
■
Manual Hex Key - This method allows you to manually enter hex keys.
Virtually all manufacturers support this scheme. Enter a two digit
hexadecimal number in every box. Hexadecimal numbers are formed
from 0-9 and A-F.
■
3Com Encryption String - This method is supported by 3Com Wireless
products. The string can contain any alphanumeric characters and
must be between 6 and 30 characters long. A single string will
automatically generate 4 unique keys for 64 or 128 bit WEP.
■
ASCII - This method is supported by some adapter cards running
under Windows XP. The string must be exactly 5 characters for 64 bit
WEP and 13 characters for 128 bit WEP. You must enter a separate
string for each of the 4 Keys. You can leave a string blank provided
this Key is not selected as the Active Transmit Key.
■
Passphrase - This is another common method and similar to the 3Com
Encryption string. In 64 bit WEP, the passphrase will generate 4
different keys. However, in 128 bit WEP, this method only generates 1
key which is replicated for all 4 keys. The passphrase can be up to 31
characters long and may contain any alphanumeric characters.
If you encounter any difficulty when you enable WEP ensure that you
check that each key on your wireless computer is exactly the same as
each key on your Router. In other words, Key number 1 on the Wireless
computer must have the same Hex number as Key number 1 on the
Router, Key 2 on the Wireless computer must match Key 2 on the Router
and so on.
