Sporadic association problems could be a problem with the chosen rates.
This would show the rates for the EAPOL frames:

iw dev wlp1s0 interface add mon0 type monitor
ifconfig mon0 up
tshark -i mon0 -Y eapol -T fields -e radiotap.datarate -e wlan -e eapol -e wlan.sa -e wlan.da
Run wpa_s.

Does setting a lower rate improve connectivity ?

'iw dev wlp1s0 set bitrates ht-mcs-2.4 1' would choose a lower
rate for the key-exchange frames.
