I am presenting a very CHARACTERISTIC error since apparently there is no online solution or...

Hello Perezper2, My name is Khaji I am an independent advisor and I will be happy to help you today.

Unfortunately, there is no permanent fix for error code 2901 in MW3. It is usually related to a connectivity issue or the game server. Here are some suggestions you can try to fix this problem:

Check your internet connection: Make sure that your Xbox is connected to the internet stably and that there are no interruptions in your connection. You can try restarting your router or switching to a wired connection instead of Wi-Fi.

Restart the console and game: Try restarting your Xbox and then starting the game again. Sometimes this can fix temporary problems.

Update the game: Make sure you have the latest game update or patch installed. Check for available updates in the game management section on your Xbox and download them if necessary.

Check the status of the servers: It may be helpful to check the Call of Duty servers for known issues or outages. You can check the official Activision support forums or follow the game's social media accounts for up-to-date information on the status of the servers.

Delete and reinstall the game: If the problem persists, you can try uninstalling the game and reinstalling it on your Xbox. This can fix issues related to corrupt or incomplete files.

Thank you very much for your patience and understanding! If you need anything else, do not hesitate to contact us again.

I wouldn't worry, it's very characteristic.

Apparently I've had GPS ultimate so long I forgot you need gold to play online.. hah. Thank you for the very simple solution.

I am stoked for the game. Loved the very first Halo ten years ago and every one since then (Okay, ODST was a bit of a let down) but I am looking forward to 4 player co-op and online multiplayer. Plus the charm of the first time I played the first installment
will still be present .
