I have a Deco XE75 kit 3 units + 2 Deco X50 units installed in my house and with around 80/90 clients (clients are iot, cameras, alexas) but I never have more than 40 clients online. I've already used the main network with 6g disabled to improve the signal, I've used the guest network and always without success. The IoT network is only for smart home and PCs and cell phones are not connected to it. I have 200 mega internet and the deco is configured as a router. The router have iot native network but with the same results. Can you explain to me why some of the devices are offline?
