Band and Channel Selection

As the number of devices in the connected home continues to grow, understanding band and channel selection can help you maximize your connected experience. To learn how to set up your network to provide each device with the best signal, you need to know how band and channel selection works and how your Wi-Fi signal operates.

Band and channel selection are important when you want to have the most efficient network possible. Your wireless data communicates using a band of frequencies. Frequency is measured in Hertz (Hz).

Our AmpliFi routers and mesh points use two of these frequencies; 2.4 GHz and 5 GHz. Most devices can use either 2.4 GHz or 5 GHz. The difference between these frequencies varies depending on your location and distance to the router. The 2.4 GHz frequency has a longer range but slower speeds; its signal can penetrate many walls. The 5 GHz has a shorter range but faster speeds; its signal is strong but is better suited to open spaces.

Here are a couple of examples:

  • In-home use: If your home has many walls, then you should use the 2.4 GHz frequency to cover the entire home.
  • Open-office use: If you have no walls between the AmpliFi router and your devices, then use the 5 GHz frequency, which is more efficient and provides a stronger signal with less range.

There is no need to select a frequency for your router in the AmpliFi app because your AmpliFi router uses both frequencies automatically. Both 2.4 GHz and 5 GHz will be available for your devices. On each of your devices, access the Wi-Fi settings if you want to select the frequency to use. (This is available only if your device supports both 2.4 GHz and 5 GHz; some devices may support only one frequency.)

You can select the frequency used by your AmpliFi mesh points in the AmpliFi app. The mesh points use the default frequency, 5 GHz, but can use 2.4 GHz instead if longer range is needed. We highly recommend keeping the mesh points close enough to the router so the mesh points use the 5 GHz frequency with more power.

    The article does not address selecting a different channel it only addresses changing the band.  I need to know how to change the channel. I have a printer conflict with epson wireless printer
