Then compare another app and another device before changing app data or resetting the Streamer. These are Google-recommended troubleshooting steps, not a guaranteed fix; the right one depends on whether the cause is Wi-Fi, the router, an app, or the device.
Start with the connection the Streamer is actually using
On the Streamer, open Settings > Network and Internet and confirm it is connected to the network you intend to use. If your router offers both 2.4 GHz and 5 GHz Wi-Fi, Google recommends checking that the Streamer is on 5 GHz when that band is supported. This is a troubleshooting option, not a promise that 5 GHz will always perform better: signal strength and conditions in your home matter, and Google does not publish controlled performance comparisons among the connection types.

- Restart the router or modem/router, following its manufacturer’s instructions.
- Unplug the Google TV Streamer, wait three seconds, then reconnect it, as Google recommends in its connection troubleshooting guidance.
- After the devices reconnect, try the same stream again and note whether the problem changes.
Check distance, placement, and interference
Google’s Wi-Fi setup guidance says the device works best within 6 metres (20 feet) of the router; its connection troubleshooting page also recommends moving the router within 20 feet. Treat that distance as a check to try, not a guaranteed Wi-Fi range or signal threshold. The guidance is available in Google’s Wi-Fi connection article and its connection troubleshooting article.
#1 Best Overall
- The Google TV Streamer (4K) delivers your favorite entertainment quickly, easily, and personalized to you[1,2]
- HDMI 2.1 cable required (sold separately)

- Up to 4K HDR with Dolby Vision delivers captivating, true-to-life detail[4]; and you can connect speakers that support Dolby Atmos for more immersive 3D sound
Try moving the Streamer away from the TV, other electronics, wires, and cables. If the router is tucked away or far from the Streamer, test a more open location closer to it. Change one thing at a time so you can tell whether placement affects playback.
Use Ethernet to distinguish Wi-Fi trouble from other causes
If you can connect the Streamer directly to your router by Ethernet, replay the same content. Google recommends a wired connection as an option for connection problems. If playback works over Ethernet but buffers over Wi-Fi, that points toward the wireless path; it does not by itself rule out a separate issue with your internet service or streaming app.

If Ethernet makes no difference, or you do not have a cable available, continue with the checks below rather than assuming the Streamer is faulty. The Streamer’s Ethernet and Wi-Fi specifications are listed by Google.
Check the router and compare other devices
- Check whether the router has a firmware update. Google includes router software among the connection checks.
- Consider how many devices are using the Wi-Fi network at once. Google recommends checking whether the network can support the connected devices.
- Try another device on the same network. If other devices also cannot connect, Google says the issue is probably with the router rather than the streaming device.
- Try another streaming app on the Streamer. If only one app has trouble, focus next on that app rather than changing router settings.
Google mentions mesh Wi-Fi as a possible way to improve wireless coverage. It is worth considering only if your checks point to a coverage problem; it is not a necessary first step or a guaranteed remedy for buffering.

Check for updates and isolate an app-specific problem
Google’s Google TV playback troubleshooting guide recommends installing available system updates and restarting the device. It also advises confirming that the selected profile matches the streaming service you are using.
If playback trouble is limited to one app and earlier checks have not helped, clearing that app’s data is a later option. Follow the app’s prompts: clearing data can affect its local state or sign-in. Avoid doing this as a general network fix when multiple apps are buffering.

Leave factory reset until last
A factory reset erases all data on the device. Google recommends trying other troubleshooting steps first. Use the reset only after the network, restart, placement, update, and app-specific checks have failed, and only if you are prepared to set up the Streamer again. See Google’s instructions for fixing problems with a Google TV device.
What the results can—and cannot—tell you
- Several devices have connection problems: the router or wider network is a more likely place to investigate than the Streamer alone, though this is not a guaranteed diagnosis.
- Only the Streamer struggles on Wi-Fi, but Ethernet playback works: the wireless connection is a likely factor.
- Only one app buffers: check that app’s state and prompts after confirming the device is updated.
- Multiple apps buffer on the Streamer, including over Ethernet: the issue is not explained by Wi-Fi alone. Check system updates and Google’s device troubleshooting guidance before considering a reset.
Google’s product specifications state that the Streamer supports up to 4K HDR at 60 fps; that describes its output capability, not a guaranteed streaming quality or connection speed. No published statistic in the cited Google support material establishes how often Streamers buffer or how likely any particular tweak is to fix it.
