In-Home Streaming Network Settings

The Steam Link leverages Steam's In-Home Streaming service. See our In-Home Streaming FAQ for more details on this technology.

If you haven't already, we also recommend checking out the Troubleshooting Network Connectivity and How do I diagnose and report network problems? articles for more background information and suggestions regarding general network troubleshooting.

In order to optimize your Steam Link’s performance, please ensure that your network settings match the settings outlined below.

For specific information on how to accomplish these tasks with your hardware, please see your modem/router’s documentation.

Enable the Performance Overlay

The In-Home Streaming Performance Overlay can help you determine if you are encountering a network-related problem. You can also use this feature to show the impact of the troubleshooting you perform.

While streaming, press F6 or Start+Y to bring up the performance graph, and look for large spikes in the cyan line. This indicates highly variable network time, which is the main indicator of streaming network issues. These will usually coincide with video stuttering or freezing.

A detailed guide of the Performance Overlay and what the displayed information means can be found in the In-Home Streaming discussion forums.

Network Band

Steam In-Home Streaming is compatible with most home networks. A wired network will provide the best result, and we highly recommend using an ethernet connection if your In-Home streaming client supports it. Wireless and powerline connections can cause intermittent failures due to interference. You can test your devices using a direct wired connection to determine if this is a problem.

Any router that supports the 802.11N or 802.11AC wireless networking protocols should work with Steam In-Home Streaming and compatible hardware, however we recommend using the newer 802.11AC wireless standard if possible. In-Home Streaming is optimized to use the 5GHz network band. Using this wireless band will reduce any potential interference and allow your streaming client to function at full capacity. Please check with your router manufacturer to ensure that your networking equipment supports this feature and that it is operating correctly. See our Improving Wireless Performance FAQ for more suggestions regarding wireless networking.

If possible, we recommend connecting your host computer using a wired network to prevent wireless traffic problems or wireless interference. Removing or turning off other wirelessly connected equipment (especially those near the In-Home streaming client, host computer, or your router) will also help reduce these issues.

Client Isolation

In order to use Steam In-Home Streaming, please ensure that Access Point/Client Isolation is disabled in your router settings.

Please note: Steam In-Home Streaming is not supported on public networks, workplace or school/university networks, guest networks, networks with gateway portals or which require a log-in, or other networks with access point/client isolation enabled. These types of networks will prevent you from connecting in most cases. Please consult your network administrator for more details.

Network Ports

In-Home Streaming uses the following ports:

  • UDP ports 27031 and 27036
  • TCP ports 27036 and 27037

Please ensure that Steam is allowed to listen to these ports in your host computer firewall software. We suggest contacting your network administrator or firewall software developer for more information.

See our Required Ports for Steam FAQ and our Using Steam with a Firewall FAQ for additional suggestions and more details on this process. Please note: If Steam or your game has updated recently, your firewall may be preventing network access even if it worked correctly before.

Device Priority/Quality of Service (QOS)

Adjusting the designated bandwidth or device priority for your streaming client and host can improve the quality of your streaming experience.

Most routers include this feature as Quality of Service (QoS) settings or Bandwidth Priority settings that can be accessed through the router administration panel, or in some cases an associated application provided by your equipment manufacturer. Make sure that your streaming client and host are prioritized in these settings.

You can also enable network prioritization within Steam In-Home Streaming settings. Go to Steam > Settings > In-Home Streaming > Advanced Host Options, and check the Prioritize Network Traffic option at the bottom.


The Steam Link is enabled to work with WPS security; however, if you encounter any issues connecting to a WPS access point, please disable WPS and use an alternative method of connecting to troubleshoot the issue.
