Setelah menginstal Ubuntu 16.04 di laptop Acer dengan Qualcom Atheros, itu tidak berfungsi. Saya mencoba ,
sudo rfkill list all
0: hci0: Bluetooth
Soft blocked: no
Hard blocked: no
1: acer-wireless: Wireless LAN
Soft blocked: no
Hard blocked: no
Lalu, diperiksa
uname -r
4.4.0-21-generic
dan, seperti yang disarankan saya mencoba,
lspci -nnk | grep -iA2 net; dmesg | grep ath10k
