2] Check the Modern Warfare II server status for outage
Activision server may be under maintenance, hence the Disconnected from Steam — Modern Warfare II issue you’re currently experiencing. So, you can first check the current Modern Warfare 2 server status at support.activision.com/onlineservices — and if the game server is down, there’s nothing much you can do at your end but wait a while for the game servers to be back up online before you can jump right back into your gameplay. On the other hand, if the servers are up and running but the issue persists, you can proceed with the next solution.
3] Run the MWII game from Battle.net Launcher
Some affected PC gamers reported they were able to work around the issue in focus by running the game from the Battle.net launcher. If the Battle.net app shows the Install button, but you have already installed the game, simply click on Locate the game below the Install button to select the folder where you installed the game. Once the correct folder is selected, the Install button will become the Play button.
So, you can give that a go and see if that works for you too! Otherwise, you can continue with the next fix.
4] Disconnect from VPN/GPN (if applicable)
Under normal circumstances, a VPN/GPN cannot speed up your internet connection — there’s one exception which is if your Internet Service Provider (ISP) has set up some sort of block usually called a bandwidth throttle on the connection that artificially limits your connection speed. That said, in any other case, a VPN can only slow down your connection.
So, if you are getting disconnected from Steam while playing Call of Duty: Modern Warfare II on your Windows 11/10 gaming rig and you’re behind a VPN, it could be due to several factors including distance, server load, and encryption – all of which with a few minor factors that have far less impact on the speed of a VPN connection is faster than that of an unprotected one. This is because of the nature of a VPN connection — normally, when you connect to the internet, you connect to your ISP server and then to the site you want to visit. When using a VPN, the connection is simply rerouted from your ISP’s server to a VPN server and then to the site.
However, you can run a speed test with the VPN both disabled and enabled. Although the result isn’t usually accurate because like any server, your ISP server can experience heavy load or something else that affects your speeds — if your first test with the VPN disabled was during one of those issues and your second test with the VPN enabled wasn’t, it could very well be that it comes out higher.

5] Switch to a wired (Ethernet) connection
In as much as the convenience that comes with the Wi-Fi connection, which is mobility amongst other factors, it can cost you some speed, especially if you connect multiple devices to the same network because wireless connections use a shared channel to transmit data to many computers, phones, gaming consoles in your home, which can slow down your speeds. In this case, at least for the duration of the gameplay, switching to a wired (Ethernet) connection can improve internet connectivity.
If for some reason you’re currently connected via ethernet and experiencing this issue, you can use the WiFi interface instead and follow the tips below to improve your connection:
- Place the wireless access point and device in the same room.
- Stop or pause any current streams and downloads.
- Disconnect any device that is not in use from the Wi-Fi network.
- Make sure your internet device is not obstructed from your computer.
- Ensure that channel selection is set to Automatic in the router admin settings (refer to the router manual).
Hope this helps.
