How to Fix Netflix Buffering in 2026: 8 Fixes That Actually Work
If you’re trying to fix Netflix buffering, you’re in the right place. These 8 fixes work on smart TVs, Fire Sticks, Rokus, and phones — and most people are back to streaming within five minutes.
Why Is Netflix Buffering?
Netflix buffers when video data can’t load fast enough to stay ahead of playback. The most common causes are:
- ▸Internet speed is too slow or unstable
- ▸Too many devices using your network at once
- ▸Your router needs a restart
- ▸The Netflix app needs clearing or updating
- ▸Netflix servers are experiencing high traffic
- ▸Your streaming device is too old to handle the stream
How Much Speed Does Netflix Actually Need?
| Quality | Minimum Speed Required |
|---|---|
| SD (Standard Definition) | 3 Mbps |
| HD (High Definition) | 5 Mbps |
| Full HD (1080p) | 15 Mbps |
| 4K Ultra HD | 25 Mbps |
Run a speed test at fast.com right now before doing anything else. If you’re under the threshold for the quality you’re watching, that’s your answer.
An older streaming device is one of the most common causes of buffering. The Fire Stick 4K handles 4K HDR streams without breaking a sweat.

Unplug your router and modem from the wall. Wait 30 seconds. Plug back in. Wait 2 minutes for the connection to fully reset. This fixes buffering more often than any other solution.
Go to Account → Playback Settings and lower the data usage per screen. This reduces the bandwidth Netflix needs and often stops buffering immediately. You can always bump it back up once the problem is resolved.
Every device on your network uses bandwidth. If someone else is streaming, gaming, or on a video call, your Netflix performance suffers. Pause other heavy internet uses while watching.
Wi-Fi is convenient but inconsistent. If your streaming device has an ethernet port, plug it directly into your router. A wired connection is dramatically more stable for streaming.
Android: Settings → Apps → Netflix → Storage → Clear Cache
Fire TV: Settings → Applications → Manage Installed Applications → Netflix → Clear Cache
Apple TV: Delete and reinstall the Netflix app
Roku: Remove and re-add the Netflix channel
An outdated Netflix app can cause buffering issues. Check your device’s app store for Netflix updates and install them.
Sometimes Netflix itself is having problems. Check our Stream Status page or Downdetector to see if Netflix is experiencing issues in your area. If it is, there’s nothing to fix on your end — just wait it out.

Netflix Buffering on Smart TV But Not Phone?
If Netflix buffers on your TV but works fine on your phone, it’s almost always a Wi-Fi signal strength issue. Your TV may be further from the router or blocked by walls. Solutions:
- ▸Move your router closer to your TV
- ▸Get a Wi-Fi extender or mesh network node near your TV
- ▸Use a wired ethernet connection if your TV has an ethernet port
- ▸Use a streaming stick (Roku, Fire Stick) — they sometimes have better Wi-Fi antennas than built-in smart TV hardware
Netflix Buffering at Night?
Evening buffering (7–11pm) is extremely common because that’s when the most people are streaming. Your ISP’s network gets congested during peak hours. If this is a consistent problem, your internet plan may be undersized for your household’s needs.
Netflix buffering on 4K content? 4K requires 25 Mbps of sustained bandwidth. Check your speed, lower quality to 1080p in playback settings, and make sure you have a Netflix Premium plan — 4K requires Premium.
Still Buffering After All 8 Fixes?
If you’ve worked through every fix and Netflix is still buffering, the issue is most likely your ISP. Run speed tests at different times of day and contact them if speeds are consistently below your plan’s advertised rate. You can also try signing out of Netflix completely and back in, or contact Netflix support directly.
