Buffering is the most common complaint about any streaming service, and in our experience the cause usually sits somewhere between the router and the screen. The good news is that this is the part you control. Work down the list in order; each check takes a minute or two, and you can stop as soon as the picture behaves.
First, one question
Is it one channel or everything? If a single channel stalls while others play smoothly, the problem probably lies with that channel’s source: skip to the end and tell us which one. If everything stutters, carry on.
The twelve checks
1. Cold-start the player and the device
Close the app completely (on Fire TV and Android TV, force-stop it from the app settings), then unplug the device for thirty seconds. Streaming sticks left running for weeks gather clutter in memory, and a cold start clears it.
2. Restart the router
Same idea, for the box most people forget. Thirty seconds unplugged, then a couple of minutes to reconnect properly.
3. Measure the speed on the device itself
A speed test on your phone next to the router says little about a TV across the house. Install a speed-test app on the streaming device and run it there. Aim for a steady 20 Mbps or so for Full HD and 35 Mbps or more for 4K.
4. See what else is using the line
A console downloading an update, a cloud backup or someone streaming 4K upstairs can swallow most of a home connection. Pause them and test again.
5. Leave 2.4 GHz behind
The 2.4 GHz Wi-Fi band reaches further but is slower and crowded with neighbours’ networks. If your router broadcasts 5 GHz, connect the TV device to that. Our comparison of Wi-Fi, Ethernet and powerline goes into detail.
6. Use a cable if you possibly can
A network cable removes most Wi-Fi problems at a stroke. Small sticks need an Ethernet adapter; most TVs and set-top boxes have a socket built in.
7. Move the router or the stick
Walls, mirrors, aquariums and the television itself all weaken Wi-Fi. A short HDMI extender that brings a stick out from behind the TV often makes a visible difference.
8. Lower the quality as a test
If a 4K or HD channel stutters, try a lower-quality version of the same channel where the line-up offers one. If that plays smoothly, your connection is the bottleneck rather than the service.
9. Enlarge the player’s buffer
TiviMate lets you choose a larger buffer in its player settings. A bigger buffer absorbs small hiccups, at the cost of a slightly slower channel change.
10. Switch the video decoder
Many Android players can decode video in hardware or in software, selectable in their player settings. If one device shows stutters or green blocks that others don’t, try the other mode.
11. Rule out a VPN or a crowded evening network
A VPN adds a detour, so switch it off for a test. And if the picture is perfect in the morning but stalls at nine at night, the congestion may be on your provider’s network. Testing on the device at both times shows the pattern clearly, and gives you something concrete to report.
12. Update everything
Update the player, the device’s system software and the router’s firmware. Older player versions in particular can handle some streams badly.
Still not right?
Send us a support ticket with the device and app, the channels affected, when it happened, your speed test result on the device and whether it’s on Wi-Fi or cable. With that, we can tell quickly whether something needs fixing on our side.
Questions
Why does it only buffer in the evening?
That’s when everyone around you is streaming, and home Wi-Fi gets busy too. A cable to the TV and the checks above solve most of it.
Will a faster broadband package fix it?
Only if the speed measured on the device is too low. Plenty of homes with 500 Mbps broadband still buffer because the Wi-Fi reaching the TV is weak.
Could the problem be on your side?
Sometimes. If several channels stall at the same moment on different devices and networks, let us know with the time; it helps us confirm and fix it.
