Chow do I fix call of duty modern warfare two error code diver?

I’d have to wait for my dad to reset the router but everything else works fine.

Just updated xbox. Game still says error code diver

Hi, I hope you're doing great out there. I am an Independent advisor and I am here to help you in regard to your concern.

Kindly check if there is an update for the game on your Xbox console.

Go to "My games and apps" > Updates > Check for updates.

Oh, if you have already tried that we don't need to do that again. Please perform an extended powercycle and reset your network hardware by following the steps below:

1. Unplug the power cable from the back of the router, modem, or gateway for 5 minutes. If you have a router and a modem, unplug the power cable from both devices.

2. Press and hold the Xbox button on your console for 10 seconds or until it turns off then wait for 2 minutes before turning it on again.

3. After 5 minutes, plug the modem or gateway in first, and wait for all the lights to return to their normal state.

4. If you are using a router, plug in the router and wait for all the lights to return to their normal state.

Would it be okay if you uninstall and reinstall the game?
