How to use MAC Filter on Huawei B315 4G modem to allow or block device

Here’s how to use MAC Filter on Huawei B315 4G modem to allow or deny connection from any devices using their MAC address. If you know the device MAC address, you can use MAC Filter function to allow and block certain device from using your Wifi network.

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.
