Packet loss in cloud gaming: what repeated drops mean

Your cloud game freezes for a moment, characters jump across the screen, or your controls stop responding even though the video keeps playing. Repeated packet loss can cause these symptoms because parts of the game’s data do not arrive when they are needed.

Check whether your connection is dropping requests repeatedly before changing settings. The Connection Stability test tracks response time, jitter, lost requests, and dropouts over a few minutes. It can show whether your connection to the test server is unstable, though it cannot measure the exact route between you and a particular game service.

Check for repeated connection loss

1. Open the Connection Stability test on the same device and network you use for cloud gaming.
2. Let it run for a few minutes without closing the page. Keep the computer or device in its usual position.
3. Note whether the test reports lost requests or dropouts, and whether they happen once or repeatedly.
4. Run it again while other people or devices are using the connection, such as during a stream, download, or backup.
5. If you use Wi-Fi, repeat the test close to the router. If possible, compare it with a wired Ethernet connection.

For a check focused on game traffic, compare the test with what happens in the game itself. The symptoms and timing matter: a few isolated losses during a quiet period are different from recurring losses that line up with freezes.

What the result means

Lost requests repeat during the test

Some requests to the test server did not get a timely response. That is evidence of instability on the path between your browser and that server, but it does not prove the game’s server or route has the same problem. If the losses happen at the same time as game freezes, the connection is a reasonable place to investigate first.

Loss appears only when other people are online

Your connection may be getting congested. A large download, cloud backup, or video upload can fill the router’s queues and delay or drop other traffic. This can affect a cloud game even when a speed test shows a high download rate.

Loss appears on Wi-Fi but not Ethernet

The wireless link is a likely contributor. Distance, walls, interference, and a busy Wi-Fi channel can make delivery less reliable. The browser cannot read Wi-Fi signal strength in dBm, so use the difference between locations or a wired connection rather than expecting a browser test to report signal strength.

Loss appears on both Wi-Fi and Ethernet

The issue may be farther along the path, such as the router, modem, internet provider, or the route to the test server. It could also be a temporary problem with the test endpoint. Repeat the check at another time and compare with another online activity before drawing a conclusion.

No loss appears, but the game still freezes

The test did not catch loss to its own server during that run. Your game may use a different route, or the problem may be rendering speed, video decoding, or the cloud gaming service itself. A smooth speed test or stability check cannot guarantee smooth play in every game.

How to reduce packet loss

1. Move closer to the router. Test with a clear path between your device and the router, then compare the result with your usual playing spot. If the loss improves nearby, consider moving the router or using Ethernet.
2. Try Ethernet if you can. Connect the gaming device directly to the router, then run the stability check again. If you use a dock or adapter, test another port or cable too.
3. Pause heavy network activity. Stop large downloads, cloud backups, and video uploads on your device and other devices, then check whether the dropouts stop. A crowded connection can cause problems even if it is not fully disconnected.
4. Check for a VPN or proxy. Temporarily turn it off and test again, if your work or privacy requirements allow it. A VPN can change the route your game traffic takes. On Windows 11, check Settings › Network & internet › VPN. On macOS, check System Settings › VPN, if that section is available for your setup.
5. Restart the router and modem. Unplug both devices, wait about 30 seconds, reconnect the modem first, and wait for it to come online before reconnecting the router. Avoid restarting during a work call or another important session.
6. Check the network connection settings. On Windows 11, open Settings › Network & internet and check whether Wi-Fi or Ethernet is connected. On macOS, open System Settings › Network. If other devices also lose connection, note when it happens and contact your internet provider.
7. Update router software and device drivers. Use the router maker’s instructions and your computer maker’s update process. If the problem began just after an update, record that timing before changing more settings.

When the problem may be in the equipment

If losses continue on Ethernet, across multiple devices, and after a router restart, check the physical connections. A loose Ethernet plug, damaged cable, or unstable power connection can interrupt service. Try a known-good cable and another router port, changing one thing at a time.

If every device drops out at the same time, the modem, router, or provider connection is more likely than one game controller or computer. Ask your provider whether they can see interruptions on the line. Replace or repair equipment only after simple cable and restart checks, especially if it is rented or under warranty.

Why a stability test is not a game test

Cloud gaming sends a continuous stream of input and video data, while a browser stability test checks requests to its own test server. The two routes can behave differently. A test with no losses is useful evidence, but it cannot certify that every game connection is clean.

Compare results under similar conditions: same device, same network, and roughly the same time of day. If the stability test stays clean but the game continues to freeze, check the service’s connection indicator and try another game or streaming session. A problem limited to one service may be outside your home network.
