I've ACER Aspire ES1 521 871T. When I brought the laptop, I installed ubuntu in it and found that it has some wifi issue. When I check connectivity or network setting the wifi option is greyed out or not selectable. But when I plug in the charger it shows up and works fine. Even after removing the charger it works. But the problem occurs again when I restart the PC. So to use wifi I've to connect charger everytime  :'(

    Turn the power management off and you will have no issues. Follow the instruction below:

    Open this file with your favorite text editor, I use nano here:

    sudo nano /etc/NetworkManager/conf.d/default-wifi-powersave-on.conf
    

    By default there is:

    [connection]
    wifi.powersave = 3

    Change the value to 2. Reboot for the change to take effect.


    Possible values for the wifi.powersave field are:

    NM_SETTING_WIRELESS_POWERSAVE_DEFAULT (0): use the default value
    NM_SETTING_WIRELESS_POWERSAVE_IGNORE  (1): don't touch existing setting
    NM_SETTING_WIRELESS_POWERSAVE_DISABLE (2): disable powersave
    NM_SETTING_WIRELESS_POWERSAVE_ENABLE  (3): enable powersave
