Thanks for the information.  After doing some more testing I found
that the association to the AP is sometimes lost and that mac80211
does not recover automatically.  You have to type the command "wpa_cli
reassociate" to trigger the stack to reassociate with the AP.  Is this
one of the things that is, or will be, fixed in later releases?
