Description of problem:
After updating to 2.6-8 yesterday WiFi conked out. AP would be visible in NetworkManager for a second, but connecting not possible, afterwards no APs detected at all. Downgrading to 2.6-7 and Wifi works again.
Fedora 26 KDE, wlan driver ar9170, wlan card TP-Link TL-WN821N v2.

Network manager log. You can see things acting up after update.
wpa_supplicant 2.6-8 has only two additional patches compared to 2.6-7 and they should only affect WPA-Enterprise connections:
- OpenSSL: use system ciphers by default (rh #1462262)
- OpenSSL: fix private key password callback (rh #1465138)
Since also NetworkManager was upgraded, maybe it's the cause of the problem?
Can you please try the following combinations and check which ones work?
Also, can you please attach trace logs for the failure, captured with:
# add '-dd' to OTHER_ARGS in /etc/sysconfig/wpa_supplicant
systemctl restart wpa_supplicant
nmcli general logging level TRACE
nmcli connection up <wifi-connection>
journalctl -u NetworkManager -u wpa_supplicant --since "2 minutes ago"
Bought a new WLAN adapter instead. All good now
