the first thing you should do is to check the blinking status of the green indicator LED blinking status. Usually, there are two kinds of blinking statuses:
1. THE green LED quickly blinks one time and repeats, which means the device has failed to
connect to the router.
2. THE green LED quickly blinks twice and repeats, which means the device has connected to the
router but fails to connect to the server.
After judging the problem, you can troubleshoot the problems accordingly with below
solutions.
8 Solutions to Failed to Connect to the Router
1. Wrong WiFi Name or PWD:
You may have entered the wrong WiFi name and password in the pairing process. Please make sure
you have entered them exactly and select remember password.
2. Weak WiFi Signal
Your device may be too far away from the router, which causes a weak WiFi signal. Please try
again with a strong WiFi signal.
3. Phone Unable to Connect to WiFi
Your router or phone may come across some error, which causes a connection failure. Please
make sure your phone can access the WiFi router and works normally. If your phone has
WiFi network in the Access Point but the device still fails to connect to the router, please refer
to the below solutions.
4. Too many devices connect to the APP
There might be too many devices connect to the APP which connects with the router, please turn off the devices or turn off the APP and try again
5. Too Many Connections to One Router

and try again.

7 Solutions to Failed to Connect to Server
1. Unable to Visit Internet
If the whole outer network cannot be accessed, then use your phone or PC to visit the Internet. If
successful, try to connect your device again.
2.Bandwidth Occupied
You may have downloaded too many files at the same time, which occupied most of the
bandwidth, thus your device did not have enough bandwidth to connect to the server. If so,
please stop downloading and try again.
3.More than one router with the same name
You may have more than one router with the same name, and your device may have
connected to the non-networked one. In this case, you should reset your router name and
choose the networked one to connect. Then try to connect your device again.
4.More than one DHCP server under one network
There may be errors existing between router topology. In this case, please check the
connection way between routers, then try again.
5.ARP Attacked
If you have checked all the above and found them no problems, maybe some terminal of the local
area network you are locating has affected the ARP virus. We suggest you to manually bind
the gateway and MAC address, then try again.
6.Firewall Settings
You may have opened a firewall or some security software. In this case, please temporarily
close them and try to connect the device again.
7.DNS Server Inaccessible
After making all the above checks and finding them no problems, the possible problem should be
DNS error. Please manually change the DNS server address and try again.
