Hello, everyone!
This post will introduce the techniques of preventing rogue devices from accessing Huawei ONT's Wi-Fi. Please find more information on the topic as you read further down.
In our daily life or at work, we use Wi-Fi to access the Internet, but sometimes the network speed suddenly slows down. It is possible that a rogue device has connected to our ONT’s Wi-Fi. Therefore, we can take the following measures to prevent others from accessing it without permission via our Wi-Fi.
1. Operate carefully when using software to access the Wi-Fi without permission. Such software uploads a user's Wi-Fi network information without notification. Other users can also find the network name of this Wi-Fi, obtain its key from the software server via a 3G or 4G network, and access it without permission.
2. Check whether the 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 easy to guess. You are advised to set the Authentication Mode as WPA-PSK/WPA2-PSK. Configure and record a password with a high-security level; for example, a password should contain digits, uppercase letters, lowercase letters, and special characters. This prevents password cracking.
The following figure shows you the details:
4. 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.
P.S. 1: This applies to the Huawei ONT’s with Wi-Fi functions (such as HG8045, HG8045A, HG8245, HG8245H, HG8245Q, HG8245T, HG8247, and HG8247H).
P.S. 2: In the case of some ONT’s, you can configure a Wi-Fi password after choosing Advanced Configuration > WLAN > 2.4G/5G Basic Network Settings on the ONT web page.
Thanks.
