-disable winxp's firewall
-dont use port 6667 to connect to a network. Most networks have a range of ports, usually within 6660-6669,7000-7001 and you can specify a port with /server some.server.here:7000
-dont use "speed patches" that supposedly increase your download speed. (note some of them effect your registry, use speed patch as your search term)
-update your router drivers/firmware. (some have said they needed to use something other than the ones supplied by the manufacturer)
Done that last night!
-connect to the server's ip instead of domain (ie, /server 123.456.789.123 instead of /server some.domain.here)
-limit how many networks or other apps you are running
Mirc is the only thing running
-some have the prob not while dcc sending, but when idle for long periods of time. try creating a channel and using a timer to make a post every so often.
I have a timer running as we speak.
-changing NIC card
Tried 3 of them.
-uninstall MSN IM
Don't have it installed
-check for patches for everything from windows to the equipment you have.
