Why does my smart plug keep dropping off Wi-Fi?

Updated October 2026 · How we answer

Signal strength and placement

Smart plugs are small devices with modest antennas, so they can struggle when placed far from the router. Walls, metal appliances, and microwaves can weaken the connection. Moving the plug closer or adding a mesh node often helps.

Check the signal strength in the app if it shows one. A weak reading points to placement rather than a faulty plug.

• Reduce walls between the plug and router
• Add a mesh node or extender if coverage is weak
• Keep plugs away from microwaves and metal cabinets

Router and network settings

Many plugs use the 2.4 GHz band, which is shared with many other devices. Make sure the router broadcasts 2.4 GHz and that the plug can connect to it. Some routers combine bands under one network name, which can confuse older devices.

Automatic channel changes on the router can cause brief disconnects. A fixed channel may stabilize the connection, though the best channel depends on your neighbors.

Power and firmware

Check whether the plug is overloaded or sharing a circuit with a space heater or large motor. Power problems can cause restarts that look like Wi-Fi drops. Update the plug's firmware through the app when updates are available.

If the problem continues, reset the plug and set it up again. Remove old saved entries that may conflict with the new setup.
