I have a Asus RT-AC87U. I have tried DD-WRT versions from 2019-present but am unable to turn off the 5GHZ radio. I have tried multiple ways to deactivate it but I still see it (and can connect to it) in the list of wifi networks.
if I name the 2.4ghz SSID DDWRT-2 and the 5GHZ DDWRT-5 it appears that the 2.4GHZ radio can be disabled, but not the 5GHZ.
I tried to disable both in the GUI (wireless network mode disabled)
I tried SES / AOSS / EZ-SETUP / WPS Button
'Turning off radio' - button appears to have no effect on radios at all
also turn off radios on boot (under SES button) does not help.
I also tried Wireless/advanced/Radio Time restrictions- always off (all times red)
does not turn off radio

Im not familiar with your router as you noted, you can schedule the radio to always be OFF or on at specific hours only.
See screenshot.
On mine I have both radios off between the hours in red, works fine. Neither are up between those times.
So IDK why it doesn't work on yours, only logs would tell, you may need click apply settings, if not a reboot just to ensure it sticks.
Works here 100% of the time.
Other ways, would be to send the interface down, here the 5G wifi radio is eth2, so make sure its the same on yours, if not find out which and use that instead.
That way you would do.
Code:
sleep5; stopservice nas; wlconf eth2 down; startservice nas
if it works you want to add this to administration tab > commands tab and save as firewall
What that will do is , when you click apply or reboot the router the radio will be turned off.
However the better method is the Radio Time Restrictions.

5GHz has the Quantenna chip. 5GHz, if it even works, cannot be turned off AFAIK, but you may be able to use those commands with some degree of luck. This device has always had it's quirks under DD-WRT.

Likely process_monitor and/or check_ps restarts it. So, setting the mode to "disabled" has no effect? Might need to investigate nvram variables if that is not having any effect to see if there is something that you can issue an nvram set against to disable the interface. That's the only other option that I can think of without looking at the associated code. _________________ "Life is but a fleeting moment, a vapor that vanishes quickly; All is vanity"

and form a a shell: wl down and wl radio off
what am I missing?
Hi there,
I had the exact same problem with this router, even with the latest release (DD-WRT v3.0-r53469 std (09/08/23)), radio scheduling always off also didn't do the trick. But I found a hack which works: If you set Radio Mode to station bridge and network mode to disabled the 5gHz device stays off completely, even after reboot.

i havent done it yet but you should be able to turn radios via CLI (commands or nvram values) _________________ Atheros

Confirmed to work. But some folks are going to try and disagree when they don't own this particular router with the Quantenna chipset involved <lol> _________________ "The woods are lovely, dark and deep,

Allow me to quote some interesting comments from other Quantenna users:
As always, the Quantenna chip has its own characteristics. It is a closed source chipset
Can't set channel. You can't disable 5.0 GHz either. Even through the schedule menu.
Set transmitter power 1 mW
The fact is that the router is connected to the Internet (to the Internet provider). And it reports an error, the red WAN indicator flashes (the icon in the form of a planet). The internet works, I just think it's a glitch.
