TROUBLESHOOTING

VESYNC APP TROUBLESHOOTING

My air purifier isn't connecting to the VeSync app.

During the setup process, you must be on a secure 2.4GHz WiFi network. Confirm that the network is working correctly.
Make sure the WiFi 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.
Try moving your air purifier closer to the router. Your phone should be as close as possible to your air purifier.
Your router may need to be at a higher location, away from obstructions.
Make sure your air purifier and router are away from appliances (such as microwave ovens, refrigerators, electronic devices, etc.) to avoid signal interference.
If you're using a VPN, make sure it's turned off while setting up your air purifier.
Disable portal authentication for your WiFi network. If portal authentication is enabled, the air purifier will not be able to access your WiFi network, and setup will fail.

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

My air purifier is offline.

Make sure the air purifier is plugged in and has power, then refresh the VeSync menu by swiping down on the screen.
Make sure your router is connected to the internet and your phone's network connection is working.
Delete the offline air purifier from the VeSync app. Swipe left (iOS®) or tap and hold (Android™), then tap Delete. Reconfigure the air purifier with the VeSync app.

Note: Power outages, internet outages, or changing WiFi routers may cause the air purifier to go offline.
