Figure 8. Providing a Wireless Client with a WEP Key
If you have a second client, that client also needs to have one of the WEP keys defined on the access
point. You could give it the same WEP key that you gave to the first station. Or, for a more secure solution,
you could give the second station a different WEP key (key 2, for example) so that the two stations cannot
decrypt each other’s transmissions.

Some Wireless client software, such as like Funk Odyssey, lets you configure multiple WEP keys and set a
transfer index on the client; then you can specify different keys to be used for station-to-access-point
transmissions. (The standard Windows wireless client software does not allow you to do this.)
To build on the previous example, using Funk Odyssey client software you could give each of the clients
WEP key 3 so that they can decode the access point transmissions with that key and also give client 1
WEP key 1 and set this as the client 1’s transfer key index. You could then give client 2 WEP key 2 and set
this as client 2’s transfer key index.
Figure 9 illustrates the dynamics of the access point and two clients using multiple WEP keys and a
transfer key index.
