Amazon Echo / Echo Dot — smart-home gadget keeps going offline
Why does my Amazon Echo / Echo Dot smart device keeps going offline?
The short answer
"Device is unresponsive" when asking it to control a plug or bulb, even though music still plays. On the WiFiXpert Compatibility Index the Amazon Echo / Echo Dot scores 84/100, and its weakest check is "Works on a guest network" — which is exactly where this problem comes from. Works for music, but smart-home control across a guest network usually fails.
We publish what breaks with each router and mesh system, and the setting that fixes it.

Free fixes, in order
- Check the plug or bulb is on the same network name as the Echo.
- Turn off any device isolation setting on the router.
- Restart the smart plug rather than the Echo — the Echo is usually not the problem.
Before you spend anything
- Rarely needed. If music stutters in one room, a mesh box helps; a new Echo will not.
