Start by connecting the Steam host PC to your router with Ethernet, then put your Android device on a strong 5 GHz Wi-Fi connection. If delay remains, use Steam’s performance overlay to check for network spikes before lowering stream quality or investigating game framerate and host encoding. Input lag can build up at several points in the stream, so changing Wi-Fi alone may not fix it.
Where streaming delay comes from
Steam Remote Play sends video and audio from the host PC to your Android device, while your controller input travels back to the PC. That round trip involves the game and host, video encoding, the home network, Android decoding and display, and the controller. A problem at any of those stages can make the game feel delayed.
Steam describes Remote Play as using a custom low-latency protocol, but its product page does not provide a measured end-to-end input-lag figure for Android. No particular setting can therefore be promised to reduce delay by a specific number of milliseconds.
Work through the likely causes
1. Connect the host PC to the router by Ethernet
Whenever practical, use Ethernet between the host PC and router while leaving the Android device on Wi-Fi. If both devices use Wi-Fi, the video stream crosses the air twice—once from the PC to the router and again from the router to Android—which can increase wireless contention. Steam recommends wiring the host where possible. See Steam’s suggested network settings and its explanation of a setup where both computer and Steam Link are wireless.

2. Improve the Android Wi-Fi connection
Try 5 GHz Wi-Fi rather than a congested 2.4 GHz network, move closer to the access point, and pause downloads or other heavy network activity while playing. Steam recommends 5 GHz because it is generally less affected by interference from neighboring networks and wireless devices. It has shorter range than 2.4 GHz, however, so a weak 5 GHz signal may perform worse than a strong nearby alternative. Check signal quality at your usual playing position rather than choosing a band by name alone.
3. Watch Steam’s performance overlay
Enable Steam’s streaming performance graph and observe it while playing. The cyan network-time line can help identify network variability: large spikes are a sign that network time is unstable and commonly coincide with stutters or freezes. Use the overlay as a clue about the network, not as a direct measurement of total controller-to-screen delay. Steam explains the graph in its network configuration troubleshooting guide.

4. Reduce stream demands if the network is unstable
If the overlay points to network trouble, try the Fast or Balanced streaming quality preset, lower the stream resolution, or reduce the bandwidth limit. Steam recommends starting with a low bandwidth limit and increasing it until hitches appear, then returning to the last stable setting. The tradeoff is reduced image quality or resolution. Its network settings guide and wireless troubleshooting steps cover these adjustments.
5. Check game framerate and host encoding
A stream can feel poor even when the network is stable. Steam identifies low game framerate and slow encoding on the host as common causes of low streaming framerate. Check whether the game itself is running smoothly on the PC, and reduce its graphics load or the stream resolution if needed. You can also test the host’s hardware-encoding options; results depend on the host GPU, so compare settings on your own system rather than assuming one encoder is always faster. See Steam’s guidance on low framerate and hardware encoding options.

Choose an adjustment that matches the symptom
| Adjustment | What it targets | Cost or tradeoff |
|---|---|---|
| Ethernet from host PC to router | The host’s wireless hop and possible wireless contention | A cable and routing effort may be needed; Android still uses Wi-Fi. Steam recommends this where practical (Steam). |
| 5 GHz Wi-Fi and better access-point placement | Wireless interference and signal quality | Usually no purchase; 5 GHz has shorter range, and results depend on signal and local conditions (Steam). |
| Fast or Balanced preset, lower resolution, or lower bandwidth limit | Stream load on a limited or unstable network | No hardware purchase, but image quality may fall (Steam). |
| Host encoding and game settings | Slow encoding or low game framerate | Usually no purchase; the useful encoding option depends on the GPU and game (Steam; Steam). |
| Router upgrade | A demonstrated weak, congested, or unsuitable wireless network | Hardware cost; a new router is not a guaranteed fix for every source of delay. Steam recommends an 802.11ac router and 5 GHz Wi-Fi (Steam). |
Retest before buying equipment
- Keep the same game, Android location, and stream settings for a baseline.
- Change one factor—for example, wire the host or move Android closer to the router—then play again under the same conditions.
- If network spikes remain, adjust Wi-Fi placement or stream demands. If the network looks stable, check game framerate and host encoding instead.
- If only one game feels delayed, compare its host-side framerate and graphics load with a game that streams smoothly before replacing network hardware.
A router upgrade is worth considering only if these checks point to the wireless network as the bottleneck. Steam recommends 802.11ac and 5 GHz for this use, but the recommendation is not evidence that Wi-Fi 6, a premium gaming router, or any particular model is necessary.

Steam’s Android Steam Link support page lists Android 5.0 or later and recommends a 5 GHz router. It names the Razer Kishi among supported controllers, but compatibility does not establish that replacing a controller will reduce end-to-end streaming delay. Confirm the app and controller work with your device before treating a controller purchase as a remedy. See Steam’s Android Steam Link requirements.
