First there is a driver or AP failure:
kernel: [ 7968.904287] wlp2s0: deauthenticated from 72:a9:e4:4f:67:c0
and the supplicant disables the AP for 10 seconds. Then the supplicant
retries and is able to authenticate and associate to the AP, but cannot
complete the 4-way handshake:
kernel: [ 7981.969561] wlp2s0: associated
wpa_supplicant: wlp2s0: Associated with 72:a9:e4:4f:67:c0
NetworkManager: <info> [1492088527.3722] device (wlp2s0):
supplicant interface state: authenticating -> associated
NetworkManager: <warn> [1492088532.3307] device (wlp2s0):
Activation: (wifi) association took too long
After this second auth/assoc, 5 seconds go by without any 4-way
handshake progress, and NM times the connection attempt out.
I don't think this is a NetworkManager or wpa_supplicant problem,
really. It seems much more like a driver or AP issue.
One really stupid question; have you power-cycled your AP? I have seen
quite a few consumer-level APs get into states like this, which a
reboot fixes temporarily.
