Here it is (not an affiliate link).  This module can plug directly into the Ethernet port on the controller main board, and powered by the 120V outlet in the back cabinet once being setup for your network.  This gives your machine the wireless functionality that is standard on 2019 machines.  I have netshare, hassconnect and remote desktop functionality wireless with this fix, the best part is its under $50!
