Hi everyone, 

I just upgraded the firmware on my tplink deco m9 plus to have the guest network isolation feature in AP-mode. 

After the upgrade, i can see the option in the wifi-menu on the deco-app, but when i activate it, my guest network still isn't isolated and i am still able to acces all LAN-devices through that network. Is that a common problem, does this need to be fixed in a future firmware-update or am i doing something wrong? 

Thanks in advance. 

Kind regards.
