Stop buffering: fixes that work, fastest first

The fix ladder

Try one change at a time. Times are estimates; check the same stream after each step.

    Restart once and wait for the network lights to settle before reopening the same stream.

When it’s not your Wi-Fi

PROVIDER

Your connection is down

If wired and wireless devices both fail, check the provider’s service status.

SERVICE

Only one app is down

Compare with another app on the same device before changing the router.

PEAK TIME

Only evenings are slow

Repeat the same test at a quiet time and keep both readings.

FAQ

Questions

Why does buffering get worse at night?

Evening downloads and nearby Wi-Fi traffic can compete with your stream. Compare the same room and device at a quieter time.

Will a faster plan stop buffering?

Only if your connection is the bottleneck. If it works beside the router but stalls by the TV, improve the signal first.
