I think quinta when the status.php I pulled when they called with the 
problem, and quinta2 was right after a reboot.  Check the dates to be 
sure...  It usually takes between 10 days, and a month for the lock to 
develop.

On a fresh power on, everything works normal.  I am not sure how the problem 
develops as I am not aware until we get calls.  At that point, a new client 
will get an IP via DHCP fine.  However, an http request will just time out. 
Clients already authenticated (Like the business center PC, often enough) 
will never time out, even with the idle timeout set.  They, and systems with 
"allowed IP addresses" will work fine.

How stable is it?  This problem only occurs in heavily used production 
systems.  If you wish, I can give you access to the to locations that have 
done this the most.
