My wifi card appears to work incorrectly.
All modules for ath9k are enabled, i can see wifi adapter in lspci but cannot see any wifi in ifconfig Do you have any idea why? I'm using ubuntu with 4.14 kernel. I tried rebooting device, remounting modules but nothing happened
ubuntu@bionic-xfce:~$ dmesg |grep ath
return nothing
