Following up for posterity, it's awkward trying to reproduce this via the
installer (which does not get around to configuring the network until after
disk setup.

From the installed system I tried wpa_cli scan followed by wpa_cli scan_results
which timed out. ifconfig wlan0 list scan does show all of the expected
networks.

This is a new machine I just purchased for FreeBSD bring-up, and the 14.0-RC4
installer is the first time I've tried FreeBSD on it.

Moving on from scanning and attempting to use the configured network:
