ˆ
In a Shared Key environment a node must authenticate itself to the
access point using a shared WEP key that is present on both the
node and the access point. Only after a node is successful
authenticated will the access point allow it access to the network.
This setting must be the same on both the wireless adapter and the
wireless router or access point.
3. Click the Data Encryption parameter and from the pull-down menu
select WEP . If in step 2 you selected Shared Key, WEP is the only
available option for the Data Encryption parameter.
4. Click the Key Length parameter and select from the pull-down menu
the desired encryption key length and type. Options are:
ˆ
64 bit hexadecimal or ASCII key (40 bit encryption key and 24 bit
initialization vector)
ˆ
128 bit hexadecimal or ASCII (104 bit encryption key and 24 bit
initialization vector)
ˆ
152 bit hexadecimal or ASCII (128 bit encryption key and 24 bit
initialization vector)
This setting must be the same on the wireless client and the access
point.
5. Enter the WEP encryption keys. You can enter from one to four keys.
The wireless client uses the encryption keys to decode the network
traffic that it receives from the access point as well as to encrypt the
network traffic that it sends to the access point. If in Step 6 you
selected Share Key, the client also uses a key when authenticating
itself to the access point.
When entering the WEP keys, note the following rules:
ˆ
The order of the keys here must match the order of the keys on the
wireless router or access point.
ˆ
Valid ASCII characters are a - z, A - Z, and 0 - 9. Valid hexadecimal
characters are 1 - 9 and A - F. (A WEP key of ASCII characters is
case sensitive.)
ˆ
The key lengths for a hexadecimal key are as follows:
– A key length of 64 bits requires 10 hexadecimal
characters.
– A key length of 128 bits requires 26 hexadecimal
characters.
– A key length of 152 bits requires 32 hexadecimal
characters.
