OpenVPN connects to router when clients on Ethernet but not on Wifi

I struggle with "Client" and "Remote".

Is this correct:

• The RS300 router is set up at the Remote location. (perhaps your home office)
• What is the primary IP subnet for the RS300?
• What IP subnet does the RS300 use for devices connected using OpenVPN?
• The Windows 11 laptops are located at the Client location (or at a public WiFi location).
• When the Windows 11 laptops are connected to the Client system using Ethernet, they receive a local IP address that is different from the IP subnet at the Remote location.
  Over Ethernet, the laptops can connect to OpenVPN and "everything works".  What is the IP address they receive from the RS300 when connected using Ethernet?
• When the Windows 11 laptops are connected to the Client system using WiFi, they receive what IP address?  What "router status" says the connection is successful?  (are these tests being conducted with the Client and Remote networks physically in the same location?

I like to set the OpenVPN log file debugging option to 5.  i.e. change 

verb 0

to

verb 5
