BF2 - "There is a problem with your connection" (?)

[Sparky1234]

Hey there everybody. Just got BF2, and oh my - what a game. I have having a little connection problem with it though, and would appreciate any advice with the issue. Sporadically during online play, I get what I guess could be described as a lag spike - the game semi locks for a second or three and I get a "There is a problem with your connection" message on the screen. Its quite annoying, it seems to happen a lot when I am a sniper, with someone in my crosshairs, or when I am flying a helicopter (finding myself upside down when the problem resolves itself). It does seem to happen at intervals of anywhere around a few minutes, and occasionally, it ends up kicking me from the server.

Any ideas as to what could be causing the problem?

I play though a wireless network, running on a D-Link wireless cable router. Could it be at all connected to this? Do I need to setup any port forwarding or such?

The game is not patched yet (downloading as we speak) - is this something that is addressed in the patch?

Could it be something really silly like the Windows firewall, or a setting in the game?

I am playing it on an AMD Barton @ 11*200, with 1gb of pc3200 at tight timings and a stock 6800gt. Settings are 1280-1024 with medium detail levels. Am I asking too much from my machine?

Thanks in advance for any help or advice.

Thanks very much for the comprehensive replies. Working under the assumption that it is due to my wireless network (patches, updates and graphic settings didn’t help), is there anything I can do, aside from running cat5 cables, to solve, or even just improve the matter? Any settings I can change on the router, port forwarding, DMZ settings or something like that?

I might very well try running a cable straight from the router, and then trying straight from the modem. I am slightly worried that it could be caused both by the fact that its a wireless network, but that I am connecting though a gateway.
