I have a problem with the wifi.

I need to plug to power to activate it.

  • LAPTOP ACER ES1-522-223C
  • Debian 8.7
  • firmware-atheros V 0.43 ath9k installed

    lspci --> 02:00.0 Network controller: Qualcomm Atheros QCA9565 / AR9565 Wireless Network Adapter (rev 01)

I have to plug the power to make it change and I can unplug the power after it starts. Even when laptop goes suspend or any similar mode I need to plug the power to get wifi working again.

When rfkill list after pluging in the power I get the following:

sudo rfkill list 
1: phy0: Wireless LAN 
    Soft blocked: no 
    Hard blocked: no 

I've tried everything I have read and I am beginning to suspect that it could be a BIOS problem or something related to the Fn+F3 key. The idea about the Fn+F3 is not really clear because the other combinations of Fn+FX are working.

Really easy. It works fine even though the Fn+F3 keys have no effect.

I added the blacklist-acer-wmi.conf file to the modprobe.d directory and the blacklist option set to acer_wmi. after that reboot.

Run this command.

echo "blacklist acer_wmi" | sudo tee /etc/modprobe.d/blacklist-acer-wmi.conf
