RT-AC86U Guest Network Not Respecting "Enable block all devices"

[glass33]

More specifically, the 2.4 GHz guest network is not respecting when I turn on "Enable block all devices". Oddly, the other 3 networks do (2.4/5 GHz regular and 5 GHz guest). I can replicate this phenomenon 100% of the time with multiple clients. I have the absolute latest firmware as of June 2022.

I contacted support and Asus gave me the most bizarre answer that this is the expected behavior, which I know is wrong. I was given a FAQ saying that the parental controls do not work when in AP mode, but I do not use this. I just use the plain, vanilla wireless router mode.

Can anyone out there confirm if they see the same behavior? Thanks

Is your guest network #1 or #2 or 3?

Is your guest network #1 or #2 or 3?

The 2.4 GHz guest network, which ignores the setting is #1. The 5 GHz guest network that obeys the setting is #2.

Ah, there ya go. Try putting the 2.4GHz guest network on net #2 or 3 and see it the situation is better for you.

I tried it, and sure enough, that did it. Guest network #1 completely ignores parental controls, while #2 and 3 obey the parental controls.

I did notice that #1 has additional options that are missing from #2 and 3. Is this difference in behavior documented anywhere?
