Hulu Keeps Buffering — Complete Fix Guide

Why Hulu Buffers Constantly

Hulu does not pre-buffer as aggressively as Netflix, so even small network hiccups are visible as repeated pauses.

Fix 1: Lower the Playback Quality

During playback, click the gear icon → Quality → Select 720p instead of Auto. Auto mode sometimes selects 4K on connections that cannot sustain it.

Fix 2: Restart Your Router

Unplug for 30 seconds and reconnect. A router running for weeks without restart accumulates stale connections that degrade streaming.

Fix 3: Close Background Apps

On smart TVs and streaming sticks, background apps consume RAM and bandwidth. Close all other apps before opening Hulu.

Fix 4: Check Hulu’s Required Speed

Hulu requires: 3 Mbps for on-demand, 8 Mbps for Live TV, 16 Mbps for 4K. Run a speed test at fast.com.

Fix 5: Change DNS to 1.1.1.1

Cloudflare’s 1.1.1.1 typically resolves to closer CDN nodes, reducing latency-induced buffering.

Fix 6: Reinstall Hulu

Delete and reinstall the app. Corrupted cached video segments can cause continuous rebuffering at the same point in a video.
