Each led sign has a unique Wi-Fi signal, the signal may starts with one of the following:
Default password: 88888888
If you didn't see any of those signals, please unplug the led sign, wait for 5 mins, then plug the sign back. Use at least two smart phones to check the signal.
If the signal still doesn't show up, it may be in "Station Mode" or it may be defective.
Station Mode: It doesn't spread signal, instead, the sign bridge into your existing network.
Defective: if you believe that the signal is defective, you can contact us to get a replacement, or use the alternative way to control the sign by USB thumb drive (details see instruction).
