|sufficient for picking a |makes iwn useless until
|new ssid |kldunload/load of if_iwn
--- Comment #1 from Hiren Panchasara <hi...@freebsd.org> ---
A few observations:
1) if a network/ssid goes away, iwn connects to the next available one without
trouble.
2) wpa_cli reassoc - works perfectly as jhb suggested
Problem occurs when I start up my phone hotspot (which has higher priority in
wpa_supplicant.conf) and try to associate with it via 'service netif restart'
as I used to.
Actually, after doing 'service netif restart' iwn doesn't associate with
anything. Which is the actual bug.

After this, only way to revive iwn is
# kldunload if_iwn; kldload if_iwn
