Here are some steps you can take to troubleshoot a media disconnected error:

1. Check your cables and connections – Make sure all of your cables and connections are securely connected and tight.
2. Power down and restart – Shut down and restart your computer and any modems, routers, or access points.
3. Check for loose connections – Make sure any external devices and ports are properly cleaned and securely inserted.
4. Update your network adapter – Download the latest driver from the manufacturer's website.
5. Check your router configuration – Make sure your router is properly configured for your network.
6. Enable UPnP – Most modern routers include Universal Plug and Play (UPnP). Make sure UPnP is enabled to ensure the router is able to connect to your network.
