Hey there. I have an ibook G4. I use Microsoft Messenger for Mac (version 7.0.1) all the time, and it usually works fine. But for some reason when I use a particular wireless router (Qwest Actiontec) it doesn't work. My web browsers, and other messenger systems (yahoo, aim, ect.) work just fine. I also have a PC which uses the same wireless router, and MSN works on that. When I connect to the neighbor's wireless network (or any other network) with my ibook, Messenger works just fine. Anyone know of anything I can do to fix this problem? The Actiontech router is my main internet connection, so not having Messenger working with it is a major inconvenience, since other connections are not always available.
