Here is a wild guess.  When you turn off the wired network the AFS
client marks the servers as "down" and they are not checked for up
to five minutes to see if they have come up again.  This check of
down servers occurs every five minutes by a daemon thread.

On Windows, I watch for notification of network interface changes and
if there is a change I wait several seconds and then immediately force
a check of down servers.
