• Verify your router is working properly with a strong and stable 2.4GHz WiFi network.
• Please make sure the signal between the Smart Sock Base and your router is stable or place your Smart Sock close to the router during the firmware update process.
• Visually confirm the Smart Sock’s LED indicator light is showing the correct status:
  • If the LED indicator light is flashing red and green alternately, it indicates that the Smart Sock is currently updating its firmware.
  • If the LED indicator light is off, please charge the Smart Sock for a few minutes until its LED indicator light turns on. Visit How do I charge my eufy Baby Smart Sock? for detailed instructions on how to charge your Smart Sock.
