Thanks, but that doesn't seem to do it.

I changed the "ifconfig_wlan0" line in /etc/rc.conf from:
ifconfig_wlan0="WPA DHCP"

to:
ifconfig_wlan0="WPA DHCP -ht"

wlan now shows up as:

(Again: times are UTC and the last part pasted above was the beginning

Well, what did you EXPECT from Trump?  He has a history of breaking promises.
