I have a notebook Lenovo Ideapad 310-15ISK and sometimes the wireless works, sometimes it doesn't.

When I turn on the notebook and the wireless works, it keep working still I turn of or reboot the notebook. When I turn on the notebook and the wireless is not working, I have to reboot or turn it on again still it works.

Note: my NB doesn`t have a physical wireless/wifi switch or a shrtcut on the keyboard. The F7 button is the airplane mode.

What I can do to fix it?

  • Sorry, i can only give you some hints: Perhaps it is a driver problem: Check askubuntu.com/questions/994555/… and askubuntu.com/questions/708061/… and github.com/kvalo/ath10k-firmware - Maybe an easy solution could be to switch to ubuntu 16.04. When you do not have any wifi connection, what is the output of lspci -knn compared to when the connection is established? – AlexOnLinux Jan 14 '18 at 23:04
  • Thank you very much Thomas. I'll try to do that according to the links above. The last times that I rebooted the NB the wifi always worked, so I don't know if it was fixed by an update or not. So when(if) it doesn't work again I post here the output of lspci -knn compared. I had ubuntu 16.04 but the problema was the same. I just switched do ubuntu 17.10 to try an earlier kernel. Thanks again. Fernando – Fernando Malavazi Jan 21 '18 at 22:41

  • I followed the instructions bellow and the problem continues. Someone can help me? Another way? I upgraded to the Ubuntu 18.04 and the problem continues. Thanks – Fernando Malavazi May 13 '18 at 23:00

    Hey Fernando, i just checked your wifi-script-output and don't see any problem. I guess your wifi-card was working properly when you did run the script. Could you rerun the script again, when your wifi is not working, so we can compare the outputs? – AlexOnLinux Jun 15 '18 at 4:28
