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. 

Additional info:
Fedora 26 KDE, wlan driver ar9170, wlan card TP-Link TL-WN821N v2.

Network manager log. You can see things acting up after update.
Comment 2 Beniamino Galvani 2017-07-24 04:50:38 EDT
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?

 1) NetworkManager-1:1.8.0-6

 2) NetworkManager-1:1.8.2-1

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
