Why does my smart plug keep going offline?

The most common causes are: (1) Weak Wi Fi signal at the outlet location smart plugs have small antennas and need a reasonably strong 2.4GHz signal. (2) Router firmware updates that temporarily drop 2.4GHz connections. (3) Too many devices on your Wi Fi network. Solutions include: moving your router closer, adding a Wi Fi extender near the plug, ensuring your router's 2.4GHz band is enabled and not merged with 5GHz, and rebooting the plug by unplugging it for 10 seconds. Zigbee plugs avoid most Wi Fi related disconnection issues.
