Ich benutze Steam Link und bin damit zufrieden. Allerdings muss ich dich vorwarnen. Du brauchst einen sehr guten Router dafür oder Kabel Anbindung. Ansonsten funktioniert es nicht
Das ist ein Teil der Troublshooting Seite von Steam:
Connect your computer to a wired network
One of the main causes of performance issues is interference. If your PC is on the wireless network and trying to send data to your router while your router is sending that data to your device or your device is talking back, they'll interfere and you'll have a choppy experience. We highly recommend making sure your computer is directly connected to the router with Ethernet.

Falls du über WLAN dein Steam Link verbinden möchtest wäre hier einiges aus den Link über diesen Text:
Connecting via a Wireless Router
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 power line 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.
For best performance we recommend using a router that supports the 802.11AC protocol. NVIDIA has created a list of recommended routers that are also good choices for Steam In-Home Streaming. If the previous option is not available to you, a router that supports the 802.11N via a 5GHz signal will be the next best choice.
To optimize your network:
Choose the 5 GHz WiFi band over the highly contested 2.4 GHz band. The 5 GHz band has a shorter range, but there is less interference from your neighbors and other wireless devices.
Choose a WiFi channel on the Access Point (AP) that isn't contested. A couple of smart phone and laptop programs are NirSoft's WiFi Scanner or NetSurveyor. You lose over 50% of your data rate when there is channel interference with your neighbors.
Set the AP to use a 5GHz channel near the top of the band; the top end starts at channel 149.
Try to see if you can connect when the AP channel width is set to at 40 MHz, over a 20 MHz width for 11n and 11ac. If 40 MHz works, then try 80 MHz that is enabled with an 11ac capable router. Higher channel bandwidths can provide faster speeds but are more sensitive to distance and other sources of RF noise.
