Steam Link

Steam Link is a hardware and software solution made by Valve Corporation for streaming Steam content from a personal computer or Steam Machine wirelessly to a mobile device or other monitor. Steam Link was originally released as a hardware device alongside the debut of Steam Machines in November 2015. Valve discontinued the Steam Link hardware device in November 2018, in favor of supporting its software-based Steam Link application for mobile devices and smart televisions, as well as providing Steam Link as a software package for the Raspberry Pi microcomputer.

Steam Link Functionality

Steam Link, whether in hardware or software form, supports the streaming of content from a personal computer running Steam to the video device (a connected television or monitor for the hardware unit, the mobile device’s screen for the software version). In this setup, the device acting as the Steam Link (the hardware unit or the mobile device in software form) enables a game controller connected to it to be used to control the game over the connection to the home computer.

Prior to March 2019, both the personal computer and the Steam Link hardware device or mobile device using Steam Link software had to be on the same internal network. With an update in March 2019, Valve introduced the Steam Link Anywhere update that allows one to stream across the internet, though the performance of the streaming will be strongly affected by the bandwidth and latency between the personal computer and device with Steam Link.

Hardware

Steam Link is a stand-alone hardware device to enable streaming of Steam content from a personal computer or a Steam Machine wirelessly to a television set, including integration of Steam Controller gamepad. The device was released along with the debut of Steam Machines in November 2015. Valve quietly discontinued the Steam Link in November 2018, in favor of supporting its software-based Steam Link application for mobile devices, smart televisions, and a software package for the Raspberry Pi.

Steam Link is listed as having the following technical specifications:

• Wired 100 Mbit/s Fast Ethernet and Wireless 802.11ac 2×2 (MIMO)
• 3× USB 2.0 ports
• Bluetooth 4.0
• HDMI out
• Support for the following control peripherals: Steam Controller, DualShock 4, Xbox One or 360 Wired Controller, Xbox 360 Wireless Controller for Windows, Logitech Wireless Gamepad F710, or keyboard and mouse

A tear-down revealed the following specific hardware parts:

• Marvell DE3005-A1 CPU
• Marvell WiFi chip 88W8897
• Vivante GC1000 GPU

The Steam Link comes with power adapters for various countries.

Software

Operating System

The Steam Link uses a modified version of Linux based on version 3.8 of the Linux kernel. It is possible to enable root SSH access to the system.

SDK

One month after release, support was added to the Steam Link to have Steam Link apps, which can be created using an SDK. A number of such apps have been created, such as apps for accessing Kodi, but no database or store for them exists as of November 2017.

Games and applications

Any Steam game that can run on the host computer can be streamed to the Steam Link. On Linux host it is also possible to stream a Windows game using the Proton beta (released August 2018). Non-Steam games can be played as well.

Discontinuation

Valve announced in November 2018 that they are no longer manufacturing the Steam Link hardware device, and will sell off the remaining stock. Valve will continue to support software and device updates to existing Steam Link hardware, but are directing users towards the mobile app to provide the same functionality.

Software

In May 2018, Valve announced it would release the Steam Link application for iOS, Android, tvOS, and Android TV devices that will allow users to play streaming games to these devices, without the need for the Link hardware. However, Apple rejected the application from its App Store because of “business conflicts with app guidelines”. The app was eventually released on iOS in May 2019. In 2018, Steam Link also released on Samsung smart TVs. In March 2021, Valve released the app for Linux and macOS.

Raspberry Pi

Valve provides a free application for single board computers Raspberry Pi 3, 3 B+, and Raspberry Pi 4 running Raspbian Stretch that provides the same functionality as the original Steam Link hardware. Valve published a beta version of the Steam Link package for Raspberry Pi on December 3, 2018. The official version was released on December 13, 2018

How to play Steam games in any room of your house

What happens if you’re gaming on your desktop Windows PC but want to continue the game from a different part of the house — or even out of the house? If you’re using Steam, Valve’s PC gaming destination, you can get around the first part of this dilemma by using Steam Link, an in-home game streaming solution that uses your local network. And now, there’s a way around the second as well — with some caveats.

While the recent release of the Steam Deck has provided gamers with a new way to play games away from their desktop, the Steam Link feature lets you stream your games from anywhere using an Android or Apple device with an internet connection (R.I.P Steam Link Box). Even though Steam Link has been out of beta for some time, the service can still be an uphill battle even for power users, so don’t be surprised if you experience inconsistent connectivity or performance.

So, let’s get started on setting up Steam game streaming from one desktop to another or between your desktop and your mobile device.

MAKE SURE YOU’VE GOT A GOOD ROUTER OR WIRED ETHERNET

This should maybe go without saying, but your network needs to be robust — if your Wi-Fi is weak, slow, congested, or there’s too much interference, you won’t see great results. With a wired ethernet connection on both ends, Steam streaming can feel practically seamless inside your own home, but it can be completely unplayable with a poor wireless link. Just keep that in mind.

SETTING UP YOUR STEAM CLIENT APPS FOR STREAMING

• Before you do any streaming (in-home or otherwise), you’ll probably want to download or update to the latest version of the Steam desktop client for the best experience. If you want to stream games to your phone, download the Steam link client to your Android or Apple device. If you’re streaming to another Windows MacOS computer, all you need is to have the latest Steam client installed there as well, with no additional software required.
• If you’re streaming to a mobile device, go to the Steam Link app settings on your phone and select “Other Computer.” A four-digit PIN will appear on your screen that you’ll enter on the desktop to complete the pairing process. If you’re using two PCs, you won’t need to pair them in order to stream in-home; just sign in to the same account on the same network.
• Using the desktop Steam client, from the “Remote Play” menu, select “Pair Steam Link,” and then enter the code seen on your phone. Make sure you’re on the same network and follow the setup wizard until the pairing process is complete.

• At this point, you could start streaming, but first, I’d recommend that you set a four-digit PIN to secure your connection between any remote apps and your PC. After all, you’re handing full remote control over your computer to another device, so you should practice good security measures. Here’s how to set a PIN for Steam Link:
• On the same “Remote Play” settings page from earlier, select the “Set Security Code” button.
• Next, set a four-digit PIN by entering it into both fields, then click on the “OK” button.

From now on, whenever you attempt to stream in-home or remotely, you’ll be required to enter the PIN.

You’re finally through the setup process! As long as you stay logged in to both Steam clients, you should be able to quickly use Steam Link streaming when you’re on your own local network — or over the public internet, from your phone. More on that below.

HOW TO STREAM GAMES REMOTELY USING STEAM LINK

• First, you’re going to need an internet connection with excellent upload speeds. Even if Comcast is giving you 150Mbps down, 5Mbps uploads aren’t going to cut it when you’re uploading a high-res video stream to the cloud.
• Assuming you’ve got that connection and your devices are paired (see earlier steps), you can start streaming games over the internet.
• For streaming from mobile, start up the Steam Link app and select the computer you added earlier.
• Select “Start Playing,” enter your four-digit PIN, and press “Connect.” Assuming your host PC isn’t asleep, it should transition to Steam Big Picture mode while simultaneously delivering a stream to your phone. In my experience, there is a slight delay in camera and input controls when used over an LTE connection on mobile, but that can vary depending on your network and location.
• Additionally, you can select different control methods within the Steam Link mobile app. From the start screen of the app, tap on Settings, followed by “Controller.” From here, you can stick with Steam’s surprisingly robust and customizable touch input or pair a controller to your phone that the host PC will recognize.

HOW TO STREAM GAMES IN-HOME USING STEAM LINK

• Streaming games on your in-home network is basically identical to streaming over the internet. You simply need to be logged in to Steam (using the same account and network) on both devices, whether they be mobile or desktop.
• With your host Windows or PC (where the game streams from) and your stream destination (Android phone, another PC, etc.) set up, simply select a game from your library on the receiving device. On Windows or macOS desktops, this would involve going to your game library and clicking “Stream” on any of your games. On the Steam Link app, simply hit the “Start Playing” button.
• Both the host PC and receiver should now display identical streams of the game in question.
