I have two systems experienced wifi connection issues after recent HEAD
update.
Both of them experiencing frequent up/down wlan0 events on boot so wireless
connection can not negotiate DHCP requests, possibly due to fact that both
connecting to the same AP.
AP capabilities list:
***** f8:1a:67:56:16:16 1 54M -74:-96 100 EPS WPA WME ATH WPS
Interesting enough that switching wpa_supplicant to version 2.6 from ports
fixes that issue completely.
Hopefully it helps.
Thank you.
