Remote connections stops working (1 reply)

Hi guys,
I have an application in php with mysql running on WampServer Version 2.2, on a computer with windows 7
The cuestion that the application worked very well, but from good to first,
in remote computers when they have been working for some time, they do not respond or wait for answers.
Accessing the application through Localhost works perfectly.
Restart the wamp and reconnect and work well.
I weigh that it was of the equipment and i migrated it to another machine, this time with windows 8.
Everything seemed to be going well, but the problems reappeared.
The way you have to work on the application is to open the connection at the top of the page and close it at the bottom.
I have 6 remote users
In the statistics of mySql does not get to have more than 8 remote connections, the usual one or two connections.

I have no idea what the problem might be, any ideas?

Thanks for all
