Using a Router with Steam

Important Note

Steam does not support gameplay on machines operating in a network DMZ - you will need to remove your machine from the DMZ in order to play through Steam.

Router issues will generally be encountered upon your initial installation of Steam, or in the event that the router's settings or firmware have been changed.

Run the Steam Connection Test

In addition to the list linked above, Dual-WAN routers are not compatible with Steam.

If you are using a wireless connection to access Steam, you may encounter intermittent connection issues related to low signal strength - it is recommended that plug your machine into your wireless router to ensure the highest level of connectivity.

Basic Router Troubleshooting

To determine if your router may be causing issues with connectivity, please observe the following troubleshooting steps:

1. Close the Steam client application
2. Bypass your router by plugging your machine directly into the incoming line from your modem
3. Restart Steam
4. If you are able to connect to Steam after bypassing your router, it is highly recommended that you reconfigure your router to work with Steam.

Find Instructions to Configure your Router

There are many different router manufacturers - if you do not have the original instruction manual for working with your router, please check your router for the manufacturer or brand name and the router's model number.

You will need to run a search for your router manufacturer's website to find instructions for configuring your router to work with Steam.
