  • General information

    The Sunrise Internet Box is equipped with a powerful, smart WLAN. When you turn the Internet Box on, you will always have two WLAN networks to choose from: a 5 GHz WLAN and a 2.4 GHz WLAN. You can use either one based on your needs.

    This is a special feature offered by the Sunrise Internet Box, which allows you to choose the best connection for your devices at home or at the office. This gives you the best stability and speed in your local network with the Sunrise Internet connection.

    The broader frequency band provides significantly better performance with the 5 GHz WLAN compared to the 2.4 GHz WLAN.

    5 GHz:

    • very wide range (starting at WLAN channel 100)
    • at 1733 Mbit/s, it's faster than the 2.4 GHz WLAN network thanks to the WLAN Standart 802.11ac WAVE II
    • 23 non-overlapping channels, which means less susceptibility to interference
    • MU-MIMO (Multi-User- Multiple Input Multiple Output) *
      This allows Wi-Fi clients that it supports to have a maximum number of antennas (and bandwidth)
    • Beam forming *
      To reduce interference between the Wi-Fi signals (which can occur, for example, with several Wi-Fi access points close to each other that are transmitting radio signals), your Sunrise Internet Box automatically "controls" the signal to go in the direction of your Wi-Fi client by detecting where the Wi-Fi client is located and then amplifying the signal from the built-in antennas based on this.
    • DFS (Dynamic Frequency Selection *
      In order to be able to use more channels for the transmission of Wi-Fi signals (channels 52 to 64 and 100 to 140), your Sunrise Internet Box regularly checks frequencies that are also used for other applications, such as weather radar. These channels typically have less traffic and allow Wi-Fi clients that support this technology to benefit from higher throughput and better coverage.

      * This feature is only available on the 5GHz (802.11ac) band and cannot be changed.           

    2.4 GHz:

    • broad range
    • at 450 Mbit/s, it's slower than the 5GHz WLAN network
    • only 3 non-overlapping channels
    • More susceptible to interference, since other systems also use the same frequencies (e.g. drones, remote controls, Bluetooth, etc.)


    • Use the 5 GHz WLAN network for media streaming and transferring music, pictures, and videos.
    • Use the 2.4 GHz WLAN network for e-mails and light Internet surfing. These applications don't use a lot of bandwidth.

    Please note that not all terminals fully support 5 GHz WLAN. In this case, use the 2.4 GHz WLAN network.

    1. In the User interface of your modem/router, click on “WLAN.”
    2. In the “WLAN” menu, click on “Security”
    3. In the section “Limit WLAN access,” activate the option called “Limit WLAN access to known hardware”
    4. Click on “Apply” to save the settings

    Only WLAN hardware that is included in the list displayed in “Limit WLAN access” can establish a connection to the WLAN network of your modem/router.

  • If your MAC address filter is activated, you can deactivate it for a short period of time to automatically let the modem/router accept the MAC address of a WLAN hardware device:

    1. In the User interface of your modem/router click on “WLAN.”
    2. In the “WLAN” menu, click on “Security”
    3. In the section “Limit WLAN access,” activate the option called “Accept all new WLAN hardware”
    4. Click on “Apply” to save the settings
    5. Connect the WLAN hardware to the wireless network of the modem/router
    6. Activate the option called “Limit WLAN access to known hardware.”
    7. Click on “Apply” to save the settings
