In view of:
wlp4s0: disassociated from e2:…:a9 (Reason: 2=PREV_AUTH_NOT_VALID)
wlp4s0: CTRL-EVENT-DISCONNECTED bssid=e2:…:a9 reason=2
wlp4s0: WPA: 4-Way Handshake failed - pre-shared key may be incorrect
wlp4s0: CTRL-EVENT-SSID-TEMP-DISABLED id=0 ssid="papospot" auth_failures=1
duration=10 reason=WRONG_KEY
According to these messages your WPA Pre-Shared Key is wrong. You can try to disable WPA and connect to it as an open network temporarily just to test the hardware and drivers.
have you tried to get more information with this option in
wpa_supplicant:
-K Include keys (passwords, etc.) in debug output.
You'd probably need to redact the logs, were you to post them.
Cheers,
David.
