For example, if you have only 4 devices in your house, but there are 6 devices that are currently connected to your network, that means, the other two are unknown connection. To prevent this, you have two options:

  • you can block that two unknown devices using their MAC address or,
  • allow only your four devices to connect to your home Wifi network.

Just to be save, you need to enable the MAC Filter in both WLAN and Security settings.

Note: This tutorial was done on Huawei B315s-936 4G modem. Other series like B310-22, B315-22, B315-608, B315-968 should have similar steps.
