  • 1.  6GHz radios are at 0dBm for one AP group

    Posted Feb 02, 2023 09:40 AM

    I have a pretty weird problem. In one of my AP groups/buildings I have 18 out of 35 APs that have a power level of 0 dBm/EIRP for the 6GHz radio. 

    Here is output from show ap bss-table:

    We have several other buildings using this 6GHz radio profile, and all buildings are using the same Virtual AP profiles. In the past this building had the 6GHz radios completely disabled on many APs and we could only get them to come back online by re-provisioning the APs with the settings they already had.
