Why does my Hulu keep buffering?

The short answer

Hulu buffers when your internet connection can’t deliver data fast enough to keep up with the video stream.

What causes buffering?

Buffering means your device is waiting for more data to arrive before it can keep playing. A few common culprits:

  • Slow internet speed — Hulu recommends at least 8 Mbps for live TV and 16 Mbps for 4K content. If your connection falls short, buffering is inevitable.
  • Wi-Fi interference — Walls, distance from the router, and other devices all weaken your signal.
  • Too many devices on the network — Every phone, tablet, and smart speaker shares your bandwidth. More devices means less speed for each one.
  • Hulu’s servers — Occasionally the problem is on Hulu’s end, especially during popular live events.
  • Outdated app or device — An old version of the Hulu app or aging hardware can struggle to process the stream.

How to fix it

Start with the easiest fixes first:

Check your internet speed

Run a speed test at fast.com. If you’re getting less than 8 Mbps, your connection is the problem.

Restart your router

Unplug it for 30 seconds, plug it back in, and wait a minute. This clears temporary issues more often than you’d expect.

Move closer to your router (or use ethernet)

Wi-Fi gets weaker with distance. If possible, connect your streaming device directly to the router with an ethernet cable for the most reliable connection.

Close other apps and devices

Pause downloads, close background apps, and ask others on your network to ease up temporarily.

Lower the video quality

In Hulu’s settings, switch from “Best Available” to a lower quality option. Less data means less buffering.

Update the app

Make sure you’re running the latest version of Hulu. Check your device’s app store for updates.

When should you worry?

If buffering happens constantly even with a strong internet connection, the issue might be your device. Older smart TVs and streaming sticks can struggle with newer app versions. In that case, upgrading your hardware may be the only real fix.

If the problem only happens at certain times of day, your internet provider may be throttling your connection during peak hours. A VPN can sometimes help confirm this.
