Common Problems

Q: Why my device stays "Offline"?

A: The newly added device needs 1–2mins to connect Wi-Fi and network. If it stays offline for a long time, please judge these problems by the green Wi-Fi indicator status:

1. The green Wi-Fi indicator quickly flashes once per second, which means that the switch failed to connect your Wi-Fi:

• Maybe you have entered a wrong Wi-Fi password.
• Maybe there's too much distance between the switch and your router, or the environment causes interference; consider getting close to the router. If failed, please add it again.
• The 5G Wi-Fi network is not supported and only supports the 2.4GHz wireless network.
• Maybe the MAC address filtering is open. Please turn it off.

If none of the above methods solved the problem, you can open the mobile data network on your phone to create a Wi-Fi hotspot, then add the device again.

2. Green indicator quickly flashes twice per second, which means your device has connected to Wi-Fi but failed to connect to the server.

Ensure steady enough network. If double flash occurs frequently, which means you access an unsteady network, not a product problem. If the network is normal, try to turn off the power to restart the switch.
