Hello Digitec & professionals, I've been using this machine for about 3 weeks and am absolutely dissatisfied with the client management via Nebula. My topology: DSL comes in via a router, which passes the signal on to the Zyxel via Gigabit LAN; the Zyxel receives the power via POE from the adapter supplied. The signal from the machine etc. is tiptop, and at the beginning (approx. 1 week) the client management also worked; since approx. 2 weeks the manual client management no longer works properly. What I understand by this: I want to lock my various devices of my children out of the WLAN if necessary. Nebula does allow this, but it has become extremely unreliable: It often shows no clients at all, even though some are active; or if I change the status of one or more clients from Allowed to Locked Out, nothing happens. I have tried everything: renewing the lease, restarting the router, updating the firmware, restarting the clients, etc.: Absolutely unsuccessful. The thing apparently decides on a whim when it obeys the commands from Nebula (whether app or directly on nebula.zyxel.com)... Now to the question: Does anyone have experience with this, and perhaps an idea what the reason could be?
