Thanks for your note.
It sounds like your Toughbooks are getting deauthenticated after
authenticating. This sort of thing is usually because the WEP keys are not
being negotiated properly.
You should note that LEAP _always_ sends a client specific WEP key to the AP,
and a Cisco AP will try to use it to talk to the client. If your clients are
configured to use a static WEP key instead of "WEP is is supplied for me
automatically", then the WEP key negotiation will fail. You should ensure
your clients are configured to use a dynamic WEP key instead of a static WEP
