Belkin RT3200 running 22.03.5, performed auc -y -b 23.05 -B 23.05.0 After reboot there were no radios, as expected, so followed @golialive's instructions here Belkin RT3200/Linksys E8450 WiFi AX discussion - #3805 by golialive and all is well.
tl;dr for fix, which must be done from a wired connection:
$ opkg update
$ opkg install kmod-mt7915-firmware
$ vi /etc/config/wireless
replace wifi-device radio0's 'option path ...' with
option phy 'wl0'
replace wifi-device radio1's 'option path ...' with
option phy 'wl1'
$ reboot
After reboot, 2g comes up right away, but DFS takes 2-3 minutes to do its scan (nothing new here, just a reminder), then the 5g radio comes up.
