Frequently Asked Questions
- Failed to pair
A: 1.If you have installed mobile security APP such as Mobile Manager or Mobile Safe Assistant, this kind of APPs may have prohibited some permissions of Mangotek. Sometimes the system will even prompt security warning, thus it leads to a failed search. To solve it, please access to this kind of App, make Mangotek as your trusted App, enter the permission settings, set all Mangotek permissions to Allowed.
Your model is too far away from the router, take it closer and retry.
3.Check if the device has auto-exited pairing mode in the pairing process.
4.Try to pair with another Wi-Fi network.
5.Try to pair with another phone.
6.Switch off and on device, then try below:
① If your model’s pairing led fast steadily blinks. Please go to Phone Settings-->Wi-Fi, find the Wi-Fi starts with ITEAD ( ITEAD-10000XXXX), enter the password 12345678. If you failed to find ( ITEAD-10000XXXX) or when you enter the password, it says “Wrong Password”, your model has hardware problem, please contact seller for return & exchange.
② If your model’s pairing led fast blinks 3 times and repeats. Please check if you have enabled “Wireless network internal isolation”.

B. If it’s still offline, please contact seller for return & exchange.
3.The LED quickly blinks twice and repeats, which means the device has connected to the router but failed to connect to the server.
① We are upgrading server or there exits server error. If the server is running normally. Please check below:
② Unable to Visit the Internet
If the extranet cannot be accessed, then use your phone or PC to visit the Internet. If successful, try to re-add your device. If you have stopped paying Internet fee or extending your network service, you can’t visit the Internet.
③ 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 to re-add your device.
④ More than one router with the same Wi-Fi SSID (name)
You may have more than one router with the same SSID, and your device may have connected to the non-networked one. In this case, you should reset your router SSID and choose the networked one to connect. Then try to connect your device again.

⑦ Firewall Settings
You may have opened firewall or some security software. In this case, please temporarily close them and try to re-add your device.
After making all above checks and find no problems but still failed, the possible problem should be DNS error. Please manually change DNS server address to 220.127.116.11. Then try to re-add your device.
