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
How to Run ACS
Step 1: Confirm Radio Profiles are Set to Auto
- In the Dashboard, navigate to: Wireless > Radio Profiles
- Select the Radio Profile you’re using.
- Under 5 GHz > Channel Assignment, ensure it is set to Auto.
- Click Save.
Step 2: Run ACS
- Go to Hardware > Access Points.
- Click the ACS tab at the top.
- Here, you will see:
- The history of ACS runs (if any have been performed).
- Any new runs you initiate.
- Click Run ACS and choose your options:
-
Run Later: Schedule ACS to run during your defined maintenance window.
- To update your maintenance window: see this article.
-
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.
- Check the box: “I understand that running ACS can cause a network disruption.”
- 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.
