Connection "issues" with Yahoo Messenger?

Perhaps one of the biggest "complaints" we get about troubleshooting Yahoo Messenger is their help section, which if you're unfamiliar with it, can send you into a mindless (and mindnumbing) endless loop... so we've taken on board the challenge of providing "one off" pages throughout our Yahoo Messenger section which brings you the bare basics of the much needed/sought after information that is often swallowed by Y!s help section, this is one such page....

If you're faced with connection issues (or rather lack of connection) then check out the ports, protocols etc below, have a play with the different options listed below (if more than one is shown) until you find what works best for you...
