I feel like this should be easier, and something in the WLAN config, but I'm not seeing it.
On one SSID I need to completely disable the 2.4GHz band. I already have a WLAN group called "no 2.4" that I use to reduce the number of APs running 2.4GHz to avoid overlap (it's a dense deployment). That works fine to fully disable the band. I just add an AP to that group, and the override in that group simply disables the 2.4 radio.
How do I now globally disable 2.4 JUST FOR ONE SSID?
