it looks like the wifi connection (or at least the wifi association with the AP) is flapping:
if I 'watch' iwconfig wlp2s0, at some point, the association succeeds (but for a very short time as seen above)

A very similar issue have been already posted:
http://www.linuxquestions.org/questi...failed-843394/
the solution was to put a clear text password which is what I 'm doing.
So I changed 'key_mgmt' in wpa_supplicant.conf as seen in manpage (
https://linux.die.net/man/5/wpa_supplicant.conf)
Code:
network={
ssid="0rang3"
key_mgmt=WPA-PSK WPA-EAP IEEE8021X NONE
psk="BLfinland980"
}
but the problem remains exactly the same.
if I put a wrong password, the interface gets associated as well (for very short time as seen in the logs above).
if I disable dhcp, the interface gets associated as well (for very short time as seen in the logs above).
any suggestion is welcome; thanx folks!
