Hardware & Devices / Weak Wi-Fi
Stop the buffering on a smart TV or streaming stick that sits too far from the router. The settings that help, and the cheap cable that beats all of them.
The 30-second fix
Restart the router and the TV or stick together — unplug both, wait 30 seconds, plug the router in first, then the TV. Then check the Wi-Fi signal reading on the TV's network screen.
If that sorted it, you are done. If not, keep reading — the rest takes about 12 minutes.
You do not need a new TV or a new router. Most buffering is a signal problem, and the cheapest fix is usually a cable.
A streaming TV or stick is the most demanding thing on your home Wi-Fi, and often the oldest. It sits against a wall, sometimes behind a metal cabinet, and it holds the signal worse than the phone in your pocket.
The fix is usually not a new TV. It is getting a stronger signal to the spot the TV actually sits in — and the most reliable way to do that is a cable.
A router and a streaming stick with power cables
Unplug the router and the TV or stick. Wait a full 30 seconds. Plug the router in first and give it a minute, then the TV. Doing them together clears the stale connection between them, which is a very common cause of buffering.
A smart TV network settings screen showing signal strength
In the TV's settings, open the network status screen. It will show a signal strength or quality reading. If it says "fair" or "weak", you have your answer — this is a signal problem, not the app.

A streaming stick on a short HDMI extension cable clear of the TV
A streaming stick plugged directly into the back of a TV, inside a metal or glass cabinet, is in the worst possible place for radio. A short HDMI extension cable gets it out into open air. It is a two-dollar fix that often does more than anything else here.
An ethernet cable running from a router to a TV
If the TV has an ethernet port, use it. It is faster and it never drops. If there is no port or no easy route, a powerline adapter (which sends the internet through your home's electrical wiring) usually beats Wi-Fi and costs far less than a new TV.
A streaming app's video quality settings screen
Most apps let you cap the picture quality. If your connection is genuinely limited, setting the app to a lower quality stops it fighting for bandwidth it does not have — and a steady 720p beats a 4K that buffers every minute.
Try the free things first: restart, band choice, move the stick. Then the cheap things: an HDMI extension, an ethernet cable, a powerline adapter. Only then consider a mesh system or a new TV — and by that point you will know exactly which problem you are solving.
If none of that helped, it is usually a hardware or account problem rather than a settings one — and that is exactly the kind of thing worth handing to someone for an hour. Book a session →
