What Is Steam Link and How Does It Work?

Steam Link is a game streaming technology developed by Valve that allows you to play games installed on your PC on another screen in your home. Instead of moving your entire gaming rig to the living room, Steam Link captures the video and audio output from your PC, compresses it, and sends it over your local network to a receiving device. That device then sends your controller, keyboard, or mouse inputs back to the PC in real time.

Originally released as a small hardware box, Steam Link is now primarily available as a free app for smart TVs, smartphones, tablets, and streaming devices. The core idea remains the same: your powerful gaming PC does all the heavy lifting, while the receiving device simply displays the stream and relays your inputs.

Because Steam Link relies on your home network to transmit data between devices, the quality of that network connection plays a huge role in how well your games run. This is where the question “Does Steam Link use Wifi?” becomes especially important.

Does Steam Link Use Wifi? The Straight Answer

Yes, Steam Link does use WiFi. In fact, WiFi is one of the most common ways people connect their Steam Link app or device to their home network. As long as both your gaming PC and your streaming device are connected to the same local network, Steam Link can communicate between them over WiFi.

However, “can use WiFi” and “works best on WiFi” are two different things. While WiFi is convenient and works well in many homes, it is more susceptible to interference, signal drops, and latency than a wired Ethernet connection. For casual games, indie titles, or turn-based strategy games, WiFi is usually perfectly fine. For fast-paced shooters, racing games, or competitive multiplayer titles, a wired connection often delivers a noticeably better experience.

WiFi vs. Wired: What’s the Difference?

When you stream games over WiFi, data travels through radio waves between your router and your devices. This introduces variables like signal strength, physical obstacles (walls, floors, furniture), and interference from other wireless devices. A wired Ethernet connection, on the other hand, sends data through a physical cable, providing a stable, consistent, and low-latency link.

So, does Steam Link use Wifi exclusively? No. You can connect your host PC, your streaming device, or both via Ethernet. Many experienced users recommend wiring at least the host PC to the router for the best results, even if the streaming device stays on WiFi.

Network Requirements for Smooth Streaming

To get a good experience with Steam Link, your network needs to meet a few basic requirements. Valve recommends the following:

  • Host PC: A computer running Steam, connected to your router via Ethernet or 5 GHz WiFi.
  • Network speed: A router capable of at least 100 Mbps for wired connections, or a 5 GHz WiFi network (802.11ac or newer) for wireless streaming.
  • Same network: Both the host PC and the streaming device must be on the same local network.
  • Low latency: Ideally under 10 milliseconds of network latency between devices for responsive gameplay.

If you’re using WiFi, the 5 GHz band is strongly preferred over 2.4 GHz. The 5 GHz band offers faster speeds and less interference, though it has a shorter range. If your streaming device is far from the router, you may experience weaker signal strength on 5 GHz, which can lead to stuttering or dropped frames.

WiFi vs. Ethernet for Steam Link: A Quick Comparison

Choosing between WiFi and Ethernet depends on your home setup, the types of games you play, and how much convenience matters to you. The table below breaks down the key differences.

Factor WiFi (5 GHz) Ethernet (Wired)

  1. Connect your host PC to the router: Use an Ethernet cable (Cat 5e or better) to plug your gaming PC directly into your router or network switch.
  2. Connect your streaming device: If your device has an Ethernet port (such as some smart TVs or streaming boxes), connect it to the router with another cable. If not, consider using a USB-to-Ethernet adapter where supported.
  3. Verify network connectivity: Confirm that both devices show an active wired connection and are on the same local network.
  4. Open Steam on your PC: Launch Steam and ensure you’re signed in.
  5. Launch Steam Link on your streaming device: Open the app and let it scan for your host PC.
  6. Pair and authorize: Enter the PIN when prompted to link the devices.
  7. Test and play: Run the built-in network test. With a wired connection, you should see excellent results. Start your game and enjoy minimal latency.

How to Optimize Your WiFi for Steam Link

If running Ethernet cables isn’t practical, you can still get great performance over WiFi by making a few smart adjustments to your network setup.

  • Use the 5 GHz band: Always choose 5 GHz over 2.4 GHz for game streaming. It’s faster and less crowded.
  • Position your router centrally: Place your router in a central, elevated location with minimal obstructions between it and your devices.
  • Reduce interference: Keep your router away from microwaves, cordless phones, and other electronics that can disrupt the signal.
  • Limit competing traffic: Pause large downloads, video streams, or cloud backups on other devices while gaming.
  • Upgrade your router: If you’re using an older router, upgrading to a WiFi 6 (802.11ax) model can significantly improve speed, range, and reliability.
  • Use a wired backhaul for mesh systems: If you use a mesh WiFi system, connect the mesh nodes with Ethernet cables when possible to reduce wireless hops.
  • Enable Quality of Service (QoS): Some routers let you prioritize gaming or streaming traffic, which can help reduce lag during busy network periods.

Troubleshooting Common Steam Link Connection Issues

Even with a good setup, you might occasionally run into problems. Here are some common issues and how to fix them:

Steam Link Can’t Find Your PC

Make sure both devices are on the same network and that Steam is running on your host PC. Check that your firewall isn’t blocking Steam or the Steam Link connection. Restarting both the router and the Steam client often resolves discovery issues.

Choppy or Stuttering Video

This usually points to network congestion or a weak WiFi signal. Try moving closer to the router, switching to the 5 GHz band, or lowering the streaming resolution and bitrate in the Steam Link settings. Wiring your host PC via Ethernet can also make a big difference.

High Input Lag

Input lag is often caused by network latency. Use a wired connection where possible, close background applications on your host PC, and enable the “Fast” streaming preset in Steam Link’s advanced settings to reduce encoding delay.

Audio and Video Out of Sync

Try restarting the stream, updating the Steam Link app, and ensuring your host PC’s graphics drivers are up to date. Reducing the streaming bitrate can also help maintain synchronization on slower networks.
