      Choosing a Channel and Frequency: How to Avoid Interference and Increase Speed

      One of the main reasons for slow Wi-Fi is channel congestion. In apartment buildings, neighbors' networks often operate on the same channel, which creates interference. Modem HG8245H v5 supports two frequencies:

      • 📡 2.4 GHz — greater signal range, but lower speed and higher channel congestion.
      • 🚀 5 GHz — high speed and less interference, but a smaller coverage area (walls and partitions weaken the signal more).

    To select the optimal channel:

    1. Go to the section WLAN → Basic.
    2. For frequency 2.4 GHz manually specify the channel from 1 to 13Recommended channels (less crowded): 1, 6, 11. Avoid automatic selection (Auto), since the modem may choose a congested channel.
    3. For 5 GHz select a channel from the range 36-48 or 149-165 (depending on what your modem supports). These channels are less susceptible to interference.
    4. Channel width (Channel Width) For 5 GHz install on 80 MHz for maximum speed (if your devices support this mode). For 2.4 GHz leave 20 MHz - a wider channel may create interference to other networks.

    To find out which channels are occupied by neighboring networks, use Wi-Fi analysis apps, such as:

    • 📱 Wi-Fi Analyzer (Android)
    • 🍎 NetSpot (iOS/macOS)
    • 💻 inSSIDer (Windows)

    If your modem supports dual network (simultaneously 2.4 GHz And 5 GHz), we recommend setting up both frequencies with different names (for example, MyHomeWiFi_2G And MyHomeWiFi_5G). This will allow devices to automatically select the optimal network.

    What to do if 5 GHz is not working?

    If the 5 GHz network is not showing up or devices are not connecting to it, check:

    1. Does your device support 5 GHz (older smartphones and laptops can only work at 2.4 GHz).

    2. Is the option enabled? Enable 5G Wi-Fi in the modem settings (section WLAN → Basic).

    3. Is the modem in standby mode? 802.11 b/g - in this case 5 GHz will be disabled.

    4. Is the modem firmware updated (outdated versions may have bugs with 5 GHz operation).

    Additional settings to improve signal and security

    In addition to the basic parameters, the modem HG8245H v5 There are several hidden features that will help optimize your network:

    1. Transmission power (Transmit Power)

    In the section WLAN → Advanced You can adjust the signal strength. The default value is 100%, but in some cases it is worth changing:

    • 📶 If the modem is near you, reduce the power to 50-70%This will reduce the load on the modem and reduce interference for neighbors.
    • 🏠 If the signal is weak in distant rooms, try increasing the power to 120% (if such an option is available). However, this may cause the modem to overheat.

    2. Filtering by MAC addresses

    This feature allows you to restrict connections to specific devices. To configure it:

    1. Enable the option MAC Filter in the section WLAN → Advanced.
    2. Select mode Allow (allow only specified MAC addresses).
    3. Add the MAC addresses of your devices (they can be found in the network settings on each gadget).

    ⚠️ Disadvantages of this method: Each time you connect a new device, you will have to manually add its MAC address to the list.

    3. Guest network

    If you have frequent guests, set up a separate network with limited access:

    1. Go to WLAN → Guest Network.
    2. Enable the guest network and give it a separate name (for example, MyHome_Guest).
    3. Set a simple password (or leave the network open, but with a speed limit).
    4. In the settings, restrict guest access to the local network (Enable AP Isolation).

    4. Firmware update

    The HG8245H v5 modem with firmware older than 2022 may have security vulnerabilities and issues with 5 GHz operation. To update the firmware:

    1. Download the latest version from the official website Huawei or get it from support Beltelecom.
