Starting with KeeneticOS 3.1, a mesh Wi-Fi technology has been added to Keenetic routers for connecting extenders in order to expand the Wi-Fi network coverage. See the Mesh Wi-Fi System article for information on this technology.
Mesh Wi-Fi activates a hidden service network (wireless transport network, backhaul network) in both bands for communication between the controller and extenders. These hidden networks are necessary for the correct operation of the Wi-Fi system and in particular, mesh Wi-Fi.
NOTE: Important! If you have only one Keenetic router in your home network, you can remove the 'Wi-Fi system controller' component of the operating system or disable the wireless transport network in the web interface without affecting the operation of your existing network.
The possibility of disabling the service hidden network has appeared since KeeneticOS 3.4. In the router's web-interface, on the 'Wi-Fi system' page, on the 'Settings' tab set the 'Backhaul connection' switch to 'Disabled'.
You can remove the 'Wi-Fi system controller' system component from the 'General system settings' page in the 'Updates and component options' section by clicking on Component options.
TIP: Note: A working hidden network affects the behaviour of the Wi-Fi LED on the device case. When the hidden network is enabled, the Wi-Fi LED will light up even if the Wi-Fi networks in the web interface are completely turned off. It also relates to the continuous operation of the backhaul service network for mesh Wi-Fi technology.
If you do not use this feature, disable the hidden network or remove the 'Wi-Fi system controller' component and then the LED behaviour will be restored to its original state.
