it is simply because all guest network is doing is mirroring the router wireless, or when you have it turned on with the AP it is mirroring the AP wireless, certain features would not be native and functional on node guest wifi, like isolating the guest network from communicating with the rest of the network and the guest network would be able to access the main. where as the guest network on the Aimesh parent router would be able to restrict such actions, but the child node wouldn't without extra help and there is no telling what kind of impact that help would have on the node guest networks already dampen performance.Various Asus engineers promised that feature at various times during the public beta cycles for the (stock) AIMesh firmware, and it has never eventuated after nearly 2 years, which may mean it was a lot harder to implement than they initially thought ... which is not to say Eric couldn’t outsmart them yet again and do it himself, just that it is definitely not trivial from what I can tell?
You can use SSH to turn on guest network on AImesh node, you will see it has not Isolation of any kind.
