Wi-Fi Optimization: Channel Selection, Power, and QoS

Even after basic setup, your network may be unstable. Causes include congested channels, a weak signal, or traffic prioritization. Let's look at how to fix this.

1. Selecting the optimal channel:

In urban areas, channels 2.4GHz are often overloaded. To find a free one:

• 📊 Use Wi-Fi analysis apps (e.g. Wi-Fi Analyzer for Android).
• 🔍 In the modem settings (Wireless → Channel) select a channel with minimal load (usually 1, 6 or 11 for 2.4GHz).
• 🎯 For 5GHz choose channels 36-48 or 149-165 (they are less busy).

2. Setting the transmission power:

If the modem is located in the corner of the apartment, reduce the power to 50-75%to reduce interference to neighbors. If the signal is weak, increase it to 100%, but watch out for overheating of the device.

3. Traffic prioritization (QoS):

Function QoS (Quality of Service) allows you to distribute bandwidth between devices. For example, you can prioritize:

• 🎮 A gaming console or PC for online gaming.
• 📺 Smart TV for 4K streaming.
• 💼 A work laptop for video conferencing.

Activate QoS in the section Advanced → QoS and add devices by their MAC addresses.

A critical feature of the ZXHN H208N: when the guest network is enabled, device isolation is automatically activated (they won't see each other). This is beneficial for security, but it can interfere with printing to a network printer or sharing files over the local network. Turns off in Wireless → Guest Network → AP Isolation.

How to find out the MAC address of a device?

On Windows: Open a command prompt (Win + R → cmd) and enter ipconfig /all. The MAC address is specified in the line Physical Address.

On Android: Settings → About phone → Status → Wi-Fi MAC address.

On iOS: Settings → Wi-Fi → ⓘ next to the network → MAC address.
