does anyone have a link that would be helpful for having a "tweaked connection"? I am about to sell this game. I only get this lag on COD not Battlefield 2 or mag. I might try and hook the ps3 directly to the cable modem tonight but if that does not fix it, this game is worthless to me. I think the game could be awesome if I had a decent connection. I was thinking about upgrading to the next tier in speed but my upload would not increase only download.
The big things, in order of importance:
Have the fastest connection you care to pay for. Upload speed is the primary consideration, but download speed won't hurt.
Use a wired connection. You can get a decent connection with wireless, but wired is always better. Always.
Your router is the next most important link in the chain. The key here is a router that can prioritize uploads from a specific IP. Some routers will claim to automatically do this for certain types of traffic, but it's always better to do it manually.
I use a linksys router with tomato firmware. The 360 is set on a static IP, an it's given the highest outbound priority, even higher than dns lookups. It's the king of my network when it's on. Tomato also allows you prioritize overheard packets like ACK, which also helps in responding to requests ASAP.
I love seeing the host migration screen cause 90% of the time it makes me the new host.
And the last big thing is to keep other traffic at a minimum. Prioritization won't help much if your wife is watching netflix while you download 5 torrents. Bitorrent in general will absolutely ruin an online game connection because it's so many tiny connections.
The small stuff:
Use a short, high quality Ethernet cable. Even cat6 is super cheap nowadays.
If you have a switch, plug the 360 wire directly into the router, not the switch. While you're at it, plug it in the closest LAN port to the WAN port.
And finally, make sure you forward the two ports needed for xbl to your 360. I forget which two they are, look it up. Some routers can do it automatically. In the network settings on the 360, you can test your connection. If it doesn't return any sort of error message telling you to reboot your router, your ports are forwarded correctly.
