What is Auto Channel Selection?

Auto Channel Selection (ACS) is a feature that helps optimize your Wi-Fi network by scanning the environment and selecting the least congested 5 GHz channel for each Access Point (AP). This reduces interference from neighboring Wi-Fi networks and improves overall performance. Currently, ACS only applies to the 5 GHz band.

​
When Should You Run ACS?

You should consider running ACS when you notice consistently high AP utilization. For example:
  • If APs report idle utilization of over 30%.
    • Idle utilization is the percentage of time an access point’s radio is not transmitting data or receiving signals, but is still occupied by overhead like beacons, other APs’ transmissions (co-channel interference, adjacent channel interference), or non-Wi-Fi devices
Running ACS allows APs to switch to cleaner channels, helping to reduce congestion.

​
How to Run ACS

​
Step 1: Confirm Radio Profiles are Set to Auto

  1. In the Dashboard, navigate to: Wireless > Radio Profiles
  2. Select the Radio Profile you’re using.
  3. Under 5 GHz > Channel Assignment, ensure it is set to Auto.
  4. Click Save.
Repeat this step for all radio profiles that have 5 GHz enabled.

Step 2: Run ACS

  1. Go to Hardware > Access Points.
  2. Click the ACS tab at the top.
  3. Here, you will see:
  • The history of ACS runs (if any have been performed).
  • Any new runs you initiate.
  1. Click Run ACS and choose your options:
  • Run Later: Schedule ACS to run during your defined maintenance window.
  • Optimize Run: Toggle on if you want ACS to run only on APs experiencing high home-channel interference.
    • This option is recommended for large networks with many APs to improve runtime.
  • Access Points:
    • Select specific APs if you only want ACS on a subset of APs.
    • Leave blank to run ACS network-wide on all online APs.
  1. Check the box: “I understand that running ACS can cause a network disruption.”
  2. Click Run.

Step 3: Monitor the Run

  • Once ACS starts, the run will appear in the history list on the left.
  • Clicking the event will display an estimated completion time.
