UltraVNC

I start the viewer on my end with reconnect enabled. The customer runs the executable on their end, but I believe that they keep being dropped and reconnected to their wireless router. When the network drops, the remote screen stops responding and does not reconnect. Maybe I am not waiting long ...

How long should I wait for a reconnect? It doesn't seem to be reconnecting at all and I end up quiting the viewer and restarting it, then have the user click connect again.
