Fix #5: Troubleshoot your internet.

If you seem to be getting the dev error 6036 only when playing the multiplayer or online mode of COD Modern Warfare 2, the problem might be caused by an error in your networking device. To fix the issue, try restarting your modem or router and see if that will work.

Manually check your internet speed.

You also want to ensure that your internet connection is fast enough to play the game. If your download and upload speed goes below 5Mbps on average, having a slow internet might be the cause of the problem. Try disconnecting other devices from your router and see if that will improve the situation. 

Use a wired connection.

Another important consideration here is to try to see if the dev error will go away when you use a wired connection instead of wireless. If your console or PC is far from the router and this causes the wifi signal to drop, relocating closer to the router might solve the issue for you.
