The main, guest and IOT "wifi networks" offer some isolation, but all devices are in the same subnet.  A device must know the wifi password to connect, they should not be "transferred" to another network if the password is not provided by the device.

 

  @David-TP I am not sure about updating the firmware manually (Warranty), why the automatic update don't just update it?

I think I just got more disappointed with tp-link. 

 

And as said I have 2 x20 connected to the main x50-5g the entire idea of having to have the ability limited to only what the main one can offer is lacking to say the lease. 

 

I just hope by next update (automatic one) things will look better.

Well see A. Some devices need to be isolated other shouldn't be. B. most of my IoT devices are actually coming through a 3rd pary mesh (lower security unfortunately) that is connected through wire to one of the x20 to gain higher security on the exit to the internet If you wish the x50-5g is the backbone router for the setup that if I was to try and setup all on the Deco system I'll need a minimum of 5~6 Satellite Deco. (way to expansive). Not to mantion I'll need to downgrade the security on the entire network (unexpectble). But must implement, the basic of management of scope and binding a Mac address to a specific ip to have clear view of the networks regardless if a device connected to hige/low security network or even if for some reason an IoT device couldn't connect to the IoT network and connected to the backup that set in the device (the main network) if bind by Mac will get an IoT address range. Maybe it is just me that is a control freak about anything and everything that is correct to the network... I don't know.

  @Bar666xp You can link IP addresses to MAC addresses.

 

Does you third party mesh act as an AP or as a Router?  If it acts as an AP (no NAT), the Deco will see each device as coming through wire, and will attach them to the main network.  If it acts as a Router, the deco will not see those devices, it will only see the Router. 

It is set as AP. I just hope the next update will make things look better. Because right now if I want IoT network I have to make a x20 a main but then I can't connect to the internet with the x50-5g (with a sim) or can I?

Well I had enough and did the beta upgrade It's definitely an upgrade from the 1.1.7 I still have to do some work to see because right now having trouble even seeing the other routers that are connected as AP but things definitely looks better than before. thank you.

BTW will I need to update the firmware manually when it will be out of beta and out as official new f/w or will the auto update do it?
