@FUBAR-BDHR: 3.6.10 working fine with FS2NetD, it's just that it requires the new server to work and so everyone playing needs to use a 3.6.10 build in order for everybody to play. The only times that it doesn't work is when no one bothers to tell me that the FS2NetD server stopped responding (crash, hang, etc.) and it goes unnoticed by me until I happen to check on it at some random point.
@Goober5000: You were definitely logged on to the 3.6.10 server, since you somehow managed to trigger a code bug that created an endless loop issue.
I think that I managed to fix the bug now, so I guess it was a good thing that it messed up on you. But it did make the server non-responsive, so give it another try since it really shouldn't matter whether you are running on a wireless card or not (unless it's a firewall issue).
