I have a Lenovo v510, running Ubuntu 16.04, and I can't get wireless networking to work.  'Enable Wi-fi' has no effect, no networks show up.  Some commands that I've tried, and their corresponding output below:

$ lspci  | grep Network
03:00.0 Network controller: Qualcomm Atheros Device 0042 (rev 31)

$ lsmod | grep ath
ath10k_pci             45056  0
ath10k_core           344064  1 ath10k_pci

$ dmesg | grep 02:00

    could you please see if you have rfkill and in case you do, show the output from rfkill list all – Christopher Díaz Riveros Aug 26 '17 at 20:28
  • Thanks Christopher, I'll edit my question to include the output to rfkill list all. – Igor Aug 27 '17 at 11:35

Well the problem is that your wifi card is hard blocked "this is like a phisical lock that some cards have"

try

sudo rfkill unblock all

and let me know if the status from the hard block changes, if not it's probably a driver issue

  • Many thanks. The command unfortunately doesn't unblock the wifi, it is still hard blocked. How should I approach the driver issue? I'm already running 16.04 and update each time upon restarting. I've also tried adding backports but this doesn't help much it seems. Thanks for any tips! – Igor Aug 29 '17 at 18:19
