I dont think that will help you stay connected, try connect to the server on a new port. default is 6667, but many servers suport more ports, look in mirc at the server and see what other ports you can use, and you can also try connect to the server IP instead of the address to the server.

to ping the server:
Code:
on *:start: {
 .timerping1 0 20 ping YOUR_SERVER
}

replace your_server with the address to the server you connect to. This goes in to your remote. ALT+R in mirc.
