Hi, i have 11 decos in my house, most of them inside the house, 3 of them exterior decos, i have bought around 12 tp link tapo cameras, some exteriors some for inside too and i made a lot of testing because they weren't functioning well with plenty of lag and poor signals, not because of poor wifi, maybe some filter on deco that I doesn't know about that doesn't let them work well. I tried on other internet source and worked much much better but on deco i cant find a 100% stable conection and im hoping you can suggest something i can do to still use "wifi router default".

i already put all of them on priority, on a "guest" network with only 2.4 ghz, disabled firewalls on the internet provider. Sometimes they go offline too on the deco app, not the camera itself. I have on total around 70 to 80 active online cliente, most of them are shelly, phones tablets, tvs. I already reset all the cameras and my decos too. I have one xiaomi camera with zero problems. Please help
