Simply put, the answer is not much.
If the connection is timing out to the server, which is what it sounds like, then the lag between your computer and the network server is too great for a timely connection.
This usually means, in my experience, a delay of 10 seconds or more.

If you're using the round robin connection address, which is the address that begins with irc. then you might try a direct address.

Please note that mIRC is an IRC client, and does not have it's own network. Also Karaoke appears to be a channel name that is occurring more and more on different networks.

You should include the actual network and/or server address that you are having difficulty with, as that server might be down, but another server on that network might be available to you.
