Deco M9+ doesn't control wifi extender?
I have Deco M9+ at home with Netgear wifi extender EX2700. In parent control, I set no internet on my son's devices at 10 pm everyday. However, he still can connect to internet. I asked him how, he said when internet disconnected on his devices, he switches his connection to wifi extender. I thought M9+ controls over the extender when it connects to M9+.
The wifi extender in the garage for my security cameras and sprinkler system. I am guessing that I can add the extender into his devices's list but I don't want to. Is there another way?
