Overview

The built-in WiFi connection on the Kerio Control NG300 series appliance keeps on dropping and that SSID disappears. The Guest interface stays stuck at Connecting, but all the LAN interfaces stay connected without any issues. A reboot of the appliance resolves the issue temporarily.

Solution

1. Login to Kerio Control as an Administrator.
2. Go to Configuration > Interfaces.
3. Double-click the Guest interface. Alternatively, you can select the Guest interface and click on the Edit button.
4. Select the IPv6 tab.
5. Uncheck the Enable checkbox and click OK.
6. Click on Apply.

Testing

The problem should no longer appear and all the interfaces should stay connected.
