This warning signifies that Connectify Hotspot could not detect a working Internet connection on the device you selected for 'Internet'. It is a warning message only and will not affect Connectify Hotspot's functionality. However, if this message is displayed, it is highly unlikely that connected devices will be able to connect to the Internet. The message is usually the result of one of two scenarios:
Selected interface is not currently connected to the Internet. To resolve this, make sure the selected interface is currently connected to the Internet.
Multiple interfaces have Internet connections. If more than one Internet connection is available, for example a wired and a wireless connection have been established, then Windows may choose to only route Internet traffic over one interface, causing connected client devices to not have Internet access. It is best to have only one Internet connection enabled at a time.
If the issue persists, please create a log file by right-clicking the Connectify tray icon and selecting “Generate Log”. Then submit a ticket to our support team with your Connectify Hotspot log file attached.
