How to Properly Choose Channels on Ubiquiti UniFi Access Points


Ubiquiti UniFi access points are renowned for their reliability and performance in providing seamless Wi-Fi coverage. One crucial aspect of optimizing the performance of your UniFi access points is selecting the right channels. In this article, we will discuss the factors to consider and the steps to follow when choosing channels for your UniFi access points.

Understanding Wi-Fi Channels

Wi-Fi channels are specific frequencies within the wireless spectrum that enable wireless devices to communicate with each other. In the 2.4 GHz band, there are 11 channels available, while the 5 GHz band offers a wider range of channels.

Choosing the appropriate channels for your UniFi access points is important to minimize interference and maximize network performance. Here are some key considerations:

1. Analyze the Wi-Fi Environment

Prior to selecting channels for your UniFi access points, it is crucial to analyze the Wi-Fi environment. This can be done using tools like the UniFi Network Controller or third-party software. Identify nearby Wi-Fi networks and their channel usage to avoid overlapping channels that can cause interference.

2. Utilize Non-Overlapping Channels

In the 2.4 GHz band, channels 1, 6, and 11 are non-overlapping, meaning they do not interfere with each other. It is recommended to use these channels to minimize interference. In the 5 GHz band, there are more non-overlapping channels available, allowing for greater flexibility in channel selection.

3. Consider Channel Width

UniFi access points support different channel widths, including 20 MHz, 40 MHz, and 80 MHz. The wider the channel width, the higher the data throughput. However, wider channels also occupy more spectrum, which can lead to increased interference. It is important to strike a balance between channel width and interference levels based on your specific environment.

4. Optimize for 5 GHz

Whenever possible, prioritize the use of the 5 GHz band over the 2.4 GHz band. The 5 GHz band offers more channels and less interference compared to the crowded 2.4 GHz band. This is particularly important in congested areas with multiple Wi-Fi networks.

5. Leverage Auto Channel Selection

UniFi access points provide an Auto Channel Selection feature that automatically selects the best channel based on the Wi-Fi environment. This feature can be enabled in the UniFi Network Controller, allowing the access points to continuously monitor and adjust channels for optimal performance.

Steps to Choose Channels on UniFi Access Points

Now that we have covered the key considerations, let’s go through the steps to choose channels on your UniFi access points:

  1. Access the UniFi Network Controller.
  2. Select the appropriate site or location.
  3. Navigate to the “Settings” tab.
  4. Click on “Wireless Networks” and select the desired network.
  5. Under the “Advanced Options” section, choose the desired channel width.
  6. Enable the “Auto Channel Selection” feature if desired.
  7. Save the changes and apply the configuration to your UniFi access points.

By following these steps and considering the factors mentioned earlier, you can ensure that your UniFi access points are operating on the optimal channels for your specific Wi-Fi environment.


Choosing the right channels for your Ubiquiti UniFi access points is essential for achieving optimal Wi-Fi performance. By analyzing the Wi-Fi environment, utilizing non-overlapping channels, considering channel width, prioritizing the 5 GHz band, and leveraging auto channel selection, you can maximize the efficiency and reliability of your UniFi network. Follow the steps outlined in this article to properly choose channels on your UniFi access points and enjoy seamless Wi-Fi connectivity.
