2. Check Your Internet Connection
The chances are high that your internet connectivity is having some issues which causes server connectivity errors to the Activision services. It’s always a better idea to check for the internet connection manually at your end by running the speed test or ping test. If the internet connection is slow or unstable then switch to another network such as wired (ethernet) to Wi-Fi or vice versa. If you’re still facing the issue, contact your internet service provider (ISP) to get better technical help.
3. Power Cycle the Wi-Fi Router
We’ll also recommend you perform a power cycle to your Wi-Fi router by following the steps below to easily clear networking glitches or temporary cache issues. Any kind of temporary networking glitches on the router might also trouble MWIII players irrespective of any platform.
