Flex radio selection causing Spoofed SSID

Hello All,

We recently rolled out some new MR57 access points. Since we're not currently using 6Ghz I set the Flex Radio Selection to 5Ghz on the RF Profile. After setting this I noticed "Spoofed SSID's" started showing up with the MAC address of a BSSSID on the same AP that is broadcasting the SSID.

So my question is, should the flex radio not be set to use 5Ghz along with the regular 5Ghz radio, or is there another setting to stop the spoofs. I did whitelist the MAC, but that didn't change anything. So far only setting the flex radio to 6Ghz worked.

Thanks

Mark

@MarkKruse5137 setting Flex Radio to 5GHz on MR57 causes it broadcast on same band as dedi 5GHz radio ==> BSSID overlap that Meraki WIDS engine flags as spoofed SSIDs... keep Flex Radio on 6GHz (or try to set on "Best Band" auto-select) to separate it from dedi 5GHz radio and eliminate false-positive alarms

Thanks for the explanation. I've set them back to 6Ghz.
