Common Problems

Q: Why does my device stay "Offline"?
A: The newly added device needs 1-2 mins to connect Wi-Fi and network. If it stays
offline for a long time, please judge these problems by the blue Wi-Fi indicator status:
1. The blue Wi-Fi indicator quickly flashes once per 2 seconds, 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, 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. Blue indicator quickly flashes twice per 2 seconds, 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, it means you accessed
an unsteady network, not a product problem. If the network is normal, try to turn off the
power to restart the switch.
