How Do I Prevent Rogue Devices from Connecting to My Huawei ONT's Wi-Fi

Hello, friend!

For Huawei ONTs with Wi-Fi functions, perform the following steps:

1. Exercise caution when using software to access Wi-Fi without permission. Such software uploads a user's Wi-Fi network information without notification. Another user can find this Wi-Fi network name, obtain the Wi-Fi network key from the software server through a 3G or 4G network, and access this Wi-Fi network without permission.

2. Check whether encryption has been performed for the Wi-Fi network. Specifically, log in to the ONT web page. On the main menu, choose WLAN > 2.4G/5G Basic Network Settings. In WPA PreSharedKey , do not select Hide. .

3. Check whether the Wi-Fi password is too simple to be cracked. You are advised to set Authentication Mode to WPA-PSK/WPA2-PSK. Configure and record a password with high security level, for example, a password containing digits, uppercase letters, lowercase letters, and special characters. This prevents password cracking.

The following figure shows the details.

Note:

For some ONTs, you can configure a Wi-Fi password after choosing Advanced Configuration > WLAN > 2.4G/5G Basic Network Settings. on the ONT web page.

By configuring MAC address filtering, you can allow only permitted devices (whitelist) to access the network, and prevent rogue devices (blacklist) from accessing the network. For details about how to configure MAC address filtering, see section : How to configure MAC address filtering to prevent unauthorized network access on Huawei ONT.

Thanks!
