Thanks. I think I solved my problem. I do have the adapter. When going thru the set up with Airport Utility, I was getting stuck on the screen after setting up a new network. It would ask me to connect the WAN to a router to get internet access, which I didn't want to do. The AX was flashing amber, not steady green, so I thought that was a problem. Reading more carefully, instructions stated that connection to internet not required, so I moved on and it now works. Thanks again.
