Hey @Kofana,

I do not believe there are any settings that would allow you to disable ethernet ports on your nodes. You would need to configure something like this through a switch connected to your Deco network. 

What you would likely be looking for is the features just now be adding to specific Deco models that allow for you to create device whitelists with Access Control settings. The features are still rolling out so keep an eye out for any firmware updates to your model. These settings would allow you to control what devices could use the ethernet connection, rather than disabling the ports entirely.

Here is the overview of the settings that come with the latest update: https://community.tp-link.com/us/home/forum/topic/621608?sortDir=ASC&page=1

  @JasonGabler,

You are correct, It is possible to be done that way. Normally, blocking ethernet connections refers to entirely shutting down a specific ethernet port on a router - you would always be able to block a specific client using a MAC Address

However, there are a few things that can be done as a workaround on the PC. Since the block is only done via a MAC address, it is possible for the MAC address of the PC to be spoofed via a privacy tool, or the connection could be changed to a wireless connection as I believe a wireless adapter will provide its own MAC address.

But yes, you are correct in that a wired device can be blocked via its MAC address.
