My smart air purifier is not connecting to the VeSync app

Here are the following things you can do to connect your air purifier to the VeSync app:

1. Make sure your phone has Bluetooth® turned on and is not currently connected to another Bluetooth device.
2. During the setup process, you must be on a secure 2.4GHz Wi-Fi network. Confirm that the network is working correctly.
3. Make sure the Wi-Fi password you entered is correct.
• There should be no spaces at the beginning or end of the password.
• Test the password by connecting a different electronic device to the router.
• If you’re manually typing in the SSID and password, double check that both are entered correctly.
4. Try moving your air purifier closer to the router. Your phone should be as close as possible to your air purifier.
5. Your router may need to be at a higher location, away from obstructions.
6. Make sure your air purifier and router are away from appliances (such as microwave ovens, refrigerators, electronic devices, etc.) to avoid signal interference.
7. If you’re using a VPN, make sure it’s turned off while setting up your air purifier.
8. Disable portal authentication for your Wi-Fi network. If portal authentication is enabled, the air purifier will not be able to access your Wi-Fi network, and setup will fail.

Note: Portal authentication means that you need to sign in to your Wi-Fi network through a web page before you can use the Internet.
