Help with packet loss please!

For the past month now, whenever I shoot any weapon on Call of Duty 4, there is a delay of about 1/2 - 3/4 second between when I fire a gun and when I hear the "click" of the shot hitting. It feels the same as it does when one plays on around 150 ping, which many will have noticed is both difficult and frustrating to play on.

Also, I'm starting to hear people on ventrillo and other voip programs that people are breaking up occasionally.

However, the problem is my ping is fine, and recently, having turned off interleaving on my line, my ping has dropped even further to around 25ms on most UK servers. This sounds great news but the problem persisted, and didn't change one bit after a fall in ping times.

Im rather stuck, because I've tried so many things to help fix the problem: (3 different routers, turned off interleaving, reinstalled OS + game around 4 times, updated PB alot, etc) and can't seem to find a fix.

I did a ping test in cmd, as well as online and im getting 0% packet loss, and great upload and download speeds. My jitter is 1ms and I have called up my ISP and they say the line is fine.

Any further tests I can run to see where the problem may lie?

Note: On the lagometer on cod4 Im getting a load of red bars every few seconds, which indicates im getting packet loss, however when I do any packet loss tests im getting 100% packets going through.

How are you connected to your router? Wireless or cable.

cable

Turn Interleaving back on. Although this does drop latency, issues you can expect are packet loss and data corruption. Due to QoS class been changed and a few other protocols that are skipped to ensure lower latency.

Also try swapping your cable from your PC to the router it could be damaged. Ensure the required ports have been allowed through your router in-order to play the game.

To see if its not the route your connection is taking is the problem in cmd type tracert <server IP>. This will trace the route between your router and the server your playing on. If there is a hop with high ping then that could be your problem. Usually a name will be next to the hops IP, If its your ISP you can phone them up and tell them the IP and they might be able to change your rconnections route.
