Loading Next Map -1 reply

Loading Next Map.... That's the message i get all the time when I\m playing multiplayer on Doom 3. I figure that it mostly happens when the ping on the server is too high or when I'm in a high action situation. Im on a new super-G d-link wireless connection and I have very few or even no problems on any other games. Anyone got a hunch on what could be the problem? If you do then thanx much Pentium 4 2.4 ghz 1 gig ddr ram radeon 9800 pro (no problems at all with it) 72 gb hard drive and stuff

Is it that you play multiplayer and that pops up? Or is it that you can't get out of loading the map?

its that that pops up during multiplayer
