Hello,

I tried to use search to find more information on this one but couldn't find any so hopefully someone who has more knowledge than I have can help me with this one

I have TP-Link Deco M4 with all the latest firmware updates and since day 1 when I bought this last Autumn I've had the option to use IoT Network but haven't used that until now. There are still some issues and like said maybe someone who knows these better than I do can clarify few things for me
 

1. Does the IoT Network functions so that when I connect a device into it it can still communicate with all of my other devices connected to my Main Network but they don't have access to the internet? - Because now it seems that when I connect my Windows 10 laptop into IoT Network it has access to the internet and I would only like it to have access to communicate with my devices on my Main Network for occasional file transfer
2. Devices connected to the IoT Network can't communicate devices connected to my Guest Network
3. If such configuration is possible could you please link me thread / guide how to do such configuration or any other guides how to achieve this kind of device isolation from the internet but still ability to communicate with other devices

Thank you!
