Home WiFi keeps disconnecting when streaming video

Why Your Home WiFi Keeps Disconnecting When Streaming Video

Ever been dumped mid-movie? Your router might be snoozing on the job. Let’s fix that hidden power-saving feature causing dropouts.

1. The Sneaky Power-Saving Culprit

You’re settled in, popcorn ready, and—bam—WiFi gone. Many modern routers include a “green” mode that powers down the radio when it thinks there’s little traffic. Problem is, video streaming isn’t constant—packets trickle, the router thinks it’s idle and naps. Cue the disconnect.

2. Spotting the Sleepy Settings

First, see if your router (or client) is using 802.11 power-save:

# On a Linux client
iw dev wlan0 get power_save

# On OpenWrt router
uci show wireless.@wifi-device[0].ps_enable

# On DD-WRT router
nvram get wl_wme_ap_ps

If you see “ON” or “1”, that’s your ticket to streaming doom.

3. Disabling Power-Save Mode

Here’s how to keep your WiFi radio awake:

1. OpenWrt

   uci set wireless.@wifi-device[0].ps_enable='0'
   uci commit wireless
   wifi

2. DD-WRT

   nvram set wl_wme_ap_ps=0
   nvram commit
   reboot

3. Linux Client Only (if router can’t be changed)

   sudo iw dev wlan0 set power_save off

After reboot or reload, your router will stay alert—no more mid-stream snoozes.

4. Common Mistakes to Avoid

• Forgetting to commit or save after changes.
• Mixing up interface names (e.g., wlan0 vs. wlan1).
• Ignoring firmware updates—some routers patch stability improvements.

5. Short, Punchy Video Hooks

• Your router is snoozing on the job!
• Stop mid-stream drops with one click.

FAQ

Why does my WiFi cut out only when I watch videos?

Streaming video sends packets in bursts. Idle gaps trigger power-saving, so the router briefly sleeps and disconnects you.

Will disabling power-save suck up more energy?

Only a few watts extra. It’s a small trade-off for uninterrupted binge sessions.

My router firmware doesn’t show power-save options—now what?

Check for a firmware update, install a custom build (OpenWrt/DD-WRT), or disable power-save on your streaming device instead.

Conclusion

No more mid-movie blackouts. By switching off that hidden power-saving feature, your WiFi stays awake, and so do you—popcorn in hand, story uninterrupted.
