Why WiFi connections are established so slowly?

[Yuri]

I just measured: 20-40 seconds elapse between the insertion of the WiFi 
card and the host obtaining IP address. This is quite slow IMHO. It is 
hard to imagine that exchanging a few packets back and forth should take 
that long.


Is something wrong with my setup? Can there be some bug that affects 
this? Or should this be considered normal?


/etc/rc.config has:

wlans_run0="wlan0"

ifconfig_wlan0="WPA SYNCDHCP"

wpa_supplicant_enable="YES"

wpa_supplicant_program="/usr/local/sbin/wpa_supplicant"


run(4), FreeBSD 12 amd64.


Thanks,

Yuri
