I. When you see below window and failed to connect to your device, try these steps:
1. Unlock or awake your device 2. Check the network connection of your device 3. Initiate AirDroid on your device And then click “Reconnect” on the web page to try connect again.
II. If it fails again and you are sure the device and the computer is under a LAN(Local Area Network), you may try connect to your device by sign in with IP address. How to: Visit the IP address shown in AirDroid on your device.
III. If your device and computer are not under a LAN(Local Area Network) then the connecting process may take a while. If you are not sure it times out, try reconnect again.
We read every comment here and on Google Play about the connection issue. It's a top priority for our product team to solve it. The updates coming in the following months will focus on improving connection reliability. Thanks.
