QUESTION
How to improve a Huawei ONT's WiFi speed (HG8045A, HG8240, HG8245, HG8247H)?
ANSWER
1. Wi-Fi speed relies on the bandwidth provided by the ISP, so the simplest way is to upgrade to faster broadband.
2. The Wi-Fi speed is affected by the Wi-Fi signal strength and quality. Ensure that the Huawei ONT is far away from interference sources such as TVs, microwave ovens, refrigerators, cordless phones and Bluetooth devices and reduce the number of obstacles between the Huawei ONT and WiFi devices (such as pads, mobile phones and laptops). You are advised to use repeaters to enhance the WiFi coverage if the area is large.
3. Using the correct radio channel. Generally, the Huawei ONT selects channels adaptively. If the network is slow or the quality turns poor from time to time, you can use a WiFi scanner such as WiFi Stumbler or WiFi Analyzer to search for the optimal channel.
4. To prevent unauthorized network access, log in to the web interface of the router and select MAC address filtering based on your requirements.
