My Deco's are running in Access point mode. A while ago I enabled the guest WiFi to try it out, quickly found it doesn't segregate the traffic in Access point mode so didn't use it.

But I forgot to disable it.

Now when j try to disable the guest WiFi from the app it just pops up a message stating "Phone or tablet disconnected" and then leaves the guest WiFi enabled.

I really need to switch it off since j didn't put any security on it while I was trying it, meaning my network is currently wide open to passersby

Thanks
