R9000 - Can't turn off WiFi using hardware on/off button

I have a Netgear Night Hawk X10 R9000 I purchased
a couple of months ago, and I’m having some issues
with the Wi-Fi button on the front......the 2nd button from
the right, next to the WPS button.

When I press and hold down the button for two seconds,
the button lights up along with the 2.4GHz, 5GHz, and
the four antennas......but here’s where it gets interesting.

When I again press and hold down the WiFi button (2nd
from the right), the button light goes out, the 2.4GHz, 5GHz,
and the antenna lights go out, BUT.....the WiFi is still active
on both the 2.4 and 5GHz bands (I still have WiFi Internet!!).

Consequently, how could I still have WiFi Internet if the lights
on the antennas are off, and the 2.4 and 5GHz lights are off also?

The only way I’ve found to turn off the WiFi is to turn off the
SSID broadcast for both the 2.4 and 5GHz bands in the router
setup, but this is a real pain.

I’ve updated to the latest firmware, but still no fix.

NOTE: I’m NOT using the WPS feature / button; whereas, I’ve
never got it to sync to any of my WiFi devices.

Any suggestions or fixes?
