How do I determine if my router is causing a Steam connection issue? How do I configure my router to work with Steam?

Basic Router Troubleshooting

It may seem obvious, but it's worth rebooting your modem, router, or modem/router combination device before trying anything else.

If your modem and router (or wireless access point) are separate devices, test with a direct connection to your modem:

1. Close the Steam client application.
2. Bypass your router by plugging your machine directly into the modem.
3. Test that your internet connection is working, then restart Steam and check connectivity.

If you are able to connect to Steam after bypassing your router, it indicates a router configuration or compatibility issue.

Router Configuration

Certain router services can cause problems with Steam. If any of the following services are enabled on your router or access point, try disabling them:

• Stateful inspection
• Dynamic packet filtering
• QoS (Quality of Service)
• UPnP (Universal Plug 'n Play)

Required Ports for Steam

All required ports to run the Steam application are listed here. It is possible that other games available on Steam will require further ports to be available.
