This is weird... or at least it seems weird to me, though some friends with Macs have said that I should expect such things with Messenger.
I was using Messenger:mac with my install and everything seemed OK. I could connect on WiFi and logged in without any trouble. I was out of WiFi reception today so logged in using 3G, which also worked fine.
However, now I cannot login to MSN messsenger using WiFi, it refuses to connect. I have tried deleting my preferences file to no avail. I even downloaded Adium to see if that works, but it does exactly the same, works under 3g but not WiFi. Now, I use MSN on my PC over the same WiFi network without an issue so I'm really stuck.
Any ideas, genii?
