Public bug reported:
Hello,
With Xubuntu 14.04, network-manager and Atheros AR9285 card, the wifi
connections were OK.
Passing Xubuntu 16.04.1, the wifi connection is KO :
At boot and reboot, research Wifi my box fails.
We must stop looking for "Disconnect" and then try to connect to other network
visible and new stop this research and then an retry with a new connection with
the WiFi SSID of my box, this third time the connection is successful.
Notes:
1) When connected to wifi, disconnecting the user in again and the wifi
connection is good in this case.
2) Orders "echo" ath9k options nohwcrypt = 1 "| sudo tee -a
/etc/modprobe.d/ath9k.conf" + "sudo echo ath9k" / etc / modules "+ change the
wireless channel has improved the problem but have not been settled.
Thanks.
