Roaming - How to determine overlapping SSIDs?

RUCKUS Team Member

We can use the AP’s CLI to verify SSIDs overlap.

With the command ‘get scanresults wifi0’ for 2.4Ghz bands and ‘get scanresults wifi1’ for 5Ghz bands, we can determine the number of overlapping SSIDs detected on the AP and their RSSI measured in dBm.

This will give us an idea of how close neighboring APs are and how high they're broadcasting their SSIDs.

For a good roaming experience and in order to reduce the Co-Channel interference and Adjacent Channel Interference as much as we can, the recommended value for overlapping SSIDs is 30 dBm or lower.

In the example below we can see a total of 8 overlapping SSIDs. The RSSI values for these SSIDs are all below the 30 dBm so we should be good for good roaming and to avoid excessive interference.


Based on the BSSID, we can tell all the SSIDs in the above output belong to the same neighbor AP, except for ‘Tony y Hazel 5G’, which BSSID is totally different.

‘get scanresults wifi0’ will give you the current channel for the 5GHz radio on the local AP. Make sure your current channel is not the same as your neighbors!


* Identify the APs of the output based on the BSSID. Using the three penultimate digits on the BSSID (ec:8c:a2:37:81:ec), we should be able to fetch the overlapping APs in the controller and confirm if this AP belongs to our system or not. If the AP belongs to our system, we should be able to adjust the power levels or channel settings:
