Figure 35 illustrates setting the WEP key 1 on a Windows client.
Figure 35. Providing a Wireless Client with a WEP Key
If you have a second client station, that station also needs to have one of
the WEP keys defined on the access point. You could give it the same
WEP key 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.
Static WEP with Transfer Key Indexes on Client Stations
Some wireless client software (like Funk Odyssey) lets you configure
multiple WEP keys and set a transfer index on the client station, 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 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 its transfer key. You could then give client 2 WEP key 2 and set this
as its transfer key index.
The following figure illustrates the dynamics of the access point and two
client stations using multiple WEP keys and a transfer key index.
