How to connect Raspberry pi when connected via twisted pair?

Question

Computer networks

I have a Raspberry pi 4 (ubuntu server 20.10), it is connected via wifi to the router, a computer (windows 10 OS) is also connected to the router, I can easily connect to the raspberry via ssh, but now I need to ping it from the computer via twisted pair cable.

On windows, the firewall is disabled
Everywhere is configured static ip
there is no ping between devices
maybe on ubuntu server it is impossible to simultaneously connect via wifi ssh and at the same time via twisted pair?
where to dig, what is needed in order for any devices to respond?

Answer 1

for example, separate wifi and ethernet into different subnets
