I’ve set my 2.4GHz radio to a fixed 20MHz channel but my 5GHz radio is currently selected to automatic frequency.
My understanding of the permitted 5GHz uses is based on https://www.cablefree.net/wirelesstechnology/unlicensed-wireless-links/using-the-5ghz-band-in-the-uk
It seems to be consistently choosing channel 46 - 5240/20-eeeC/ac/P(17dBm) after every reboot, which suggests it is not making use of channels where DFS can be used with greater transmit power. My understanding of the function of DFS is that it should be scanning channels prior to enabling the radio. It appears at the same time as the 2.4GHz radio on a fixed allocation, so I don’t believe this is occurring.
See relevant config below, I have re-named the real SSID names to the VLAN name. I am not using the “Management” SSID on the physical interface and I am thinking I should move one of the virtual interfaces onto this instead.
Regulatory domain forces a minimum antenna gain of 3 however I understand this hardware is actually 2.5 (although it’s not possible to set a decimal place)
