[100% fixed] error code 11642 in Call of Duty: Modern Warfare 2

SOLUTION:1.Disabling your firewall

If you have a firewall installed on your computer, make sure it’s not blocking connections to the Activision servers by disabling it. This is something you’ll want to check regardless of the error code you’ve received, so it’s a good place to start. Disabling your firewall will only affect your ability to play MW2. You’ll still be able to browse the Internet and use other applications normally. To do this, go to your firewall software and deactivate the program. Make sure your firewall is not blocking connections to the Activision servers. This will help you get into the game and resolve the issue. If you have a firewall installed on your router, you’ll need to contact your ISP to have them disable it. This will affect all users connected to your network, so make sure to tell them that you need to temporarily disable the firewall.

SOLUTION:2.Resetting your Network Settings

This is another step you might want to try before trying anything else. It will reset your network settings and re-associate the IP address with your router, so you’ll need to re-associate your Xbox Live account with your console once you’ve tried this. To do this, go to the console’s Settings and select Network. Select Wired Network or Wireless Network (depending on your console) and select Reset Network Settings. This will reset your Network Settings, re-associate your IP address with your router and should resolve the Error 11642. One thing to keep in mind is that this will also clear out your NAT settings, so you’ll need to re-configure the NAT settings on your router. This will likely reset your router’s IP address as well, so you’ll need to re-associate your Xbox Live account with your console once you’ve tried this. You’ll also need to re-enter any port forwarding or DMZ settings that may have been set up on your router.

SOLUTION:3.Clearing the Cache

Another thing you can try is clearing out the game’s cache. This will clear out any temporary data and sometimes resolving network issues. To do this, go to your computer’s Start menu and select Run (or press the Windows key + R on your keyboard). This will open up the Run dialog box. Type the following in the Run dialog box and click the OK button: To clear the game’s cache on the Xbox 360, go to the Settings tab, select System and select Storage. Select your game’s title and select Clear Cache. This will clear out any temporary data and sometimes resolving network issues.

SOLUTION:4.Checking your NAT type and port settings

If you’re still getting the error code, you may have an issue with your router’s NAT type and/or port settings. To check your NAT type, there are a couple of websites that you’ll want to use. One of those websites is Port Forward, which is a website that helps you configure your router and see what your NAT type is. You should also be able to find this information in your router’s settings. The next thing you want to check is your port settings. You’ll need to make sure your port settings are correct and match the port settings listed below. If they don’t match, you’ll want to change them. To do this, log into your router and go to the port forwarding or DMZ settings. You’ll want to set up a port forwarding rule to map the port listed below to the IP address listed below: Port: 80 - Auto Map IP Address:

192.168.0.1 Port: 80 - Auto Map IP Address: 192.168.0.1 Port: 1750 IP Address: 192.168.0.1 Port: 12000 - 12999 IP Address: 192.168.0.1 Port: 88 IP Address: 192.168.0.1 Port: 3074 IP Address: 192.168.0.1 Port: 25, 80, 110, 443, 465, 995, 119, 993, 995, 2082, 2083 IP Address: 192.168.0.1

SOLUTION:5.Reinstalling the game

If you’ve tried all of the above and you’re still getting the error code, you may want to try uninstalling and reinstalling the game. This will clear out any temporary data and sometimes resolving network issues. You’ll want to make sure you have saved any game data you may have created (such as your ranking, player stats, etc.). To uninstall the game, go to the console’s Settings and select System. Select Storage and select your game’s title. Select Uninstall and the console will remove the game from the console. Next, download a fresh copy of MW2. Install the game and then log into your account. Once logged in, you should be able to play the game without any issues.
