However, if I boot from the previous kernel in the list: CentOS Linux 3.10.0-693.11.1.el7.x86_64 7 (Core), then the wifi adapter is found and works.
Running with 693.11 (instead of 693.17), iwconfig now shows:

I could just continue using the older kernel, but that is not a satisfying answer. Any suggestions?
Thanks,
