2135CN SERVER ADDRESS QUESTION

I'm trying to setup my printer to scan over the network. The printer is connected to a wireless router via an ethernet connection. My PC is connected to the same router via a wireless connection. The setup instructions state to run ipconfig at the PC's cmd prompt and input the ethernet adapters IPv4 address as the server address in the EWS portal.

The problem is, the ethernet adapter is disconnected (so no IPv4 address) presumably because I'm connected to the router wirelessly. Also, there is no ethernet port on this PC.  I tried using the wireless LAN IP but it doesn't work. I get SMB errors. Which IP address should I use given that I don't have an ethernet LAN connection?
