I have a ubuntu 16.04, windows 10 asus dual boot.

I saw a similar (but not the same) question posted to this one at this link: Intel Centrino Wireless-N 2230 won't connect, keeps asking for password.

My wireless connects but no data is transferred, I can't load google, etc. I typed in:

lspci -knn | grep Net -A3

And received:

03:00.0 Network controller [0280]: Qualcomm Atheros QCA9565  / AR9565 Wireless Network Adapter [168c:0036] rev(01)
Subsystem: Lite-On Communications Inc QCA9565 / AR9565 Wireless Network Adapter [11ad:0662]
Kernel driver in use: ath9k
Kernel modules : ath9k

I tried the fixes suggested, but I do not have the /etc/modprobe.d/iwlwifi-opt.conf file, only a /etc/modprobe.d/iwlwifi.conf file. I tried to adapt for atheros vs. intel, but I lack the proper know how.

What should my next steps be?


EDIT 1: I entered the following command as suggested by user nadav mavor:

sudo ifconfig -a ping

I received:

SIOCSIFADDR: No such device
ping: Error while getting interface flags: No such device

Edit 2: Corrected the command inputs. I entered:

sudo ifconfig

and received:

  • It will make no good if you try solutions written for Intel to fix your Atheros issue. – Pilot6 Apr 17 '17 at 17:11
  • can you add the output of the follow commands : ifconfig -a ping and iwconfig – Nadav Mavor Apr 17 '17 at 17:12
  • I tried to adapt them as I could. But I didn't know enough. thats why I'm posting here – EMP Apr 17 '17 at 17:13
  • @NadavMavor I enterred your commmands, and wrote the output back in an edit – EMP Apr 17 '17 at 17:19
  • one command at time "ifconfig -a" then "ping -c2" and last "iwconfig" all using sudo – Nadav Mavor Apr 17 '17 at 17:36

ok its clear that you didn't get DNC from your network the fast and easy was of fix will be to just add by heand :

1) as root edit /etc/resolvconf/resolv.conf.d/base and put


it will add 2 name servers to your system (google one and openDNS one )

2) restart your network "/etc/init.d/networking restart"
3) test the new DNS "ping -c2 google.com"

new your system can work and your next step is to talk to your network manager to see why your system do not geting the proper DNS config

  • Thanks! will this fix work when im on other wifi connections? Its been a problem at home and at work (different wifis). thanks again! – EMP Apr 17 '17 at 22:18
  • Hi nadav, this happened again, the file still shows those two servers, but it won't work on a different Wi-Fi now. Is there a permanent fix for This? – EMP May 16 '17 at 18:35
