Hi, i'm not really sure what's wrong with my deco, i've got one deco acting as my main modem(plugged directly into the main isp ethernet). So i was trying to use multiple of my amazon echo devices at once as a bunch but the alexa app told me that my router is likely isolating clients, i looked it up and tried every method i could to fix this but nothing seemed to lead anywhere, and i don't have a security tab in my deco app, i don't have an option called AP isolation either, can someone help me out with this?
