I have installed elementary os with a dual boot on my laptop. Nevertheless, I can't connect my computer to the wifi because the wireless icon doesn't appear in settings. I've look in the web but I haven't find a working solution. Do you have any idea to help me please ?
libappindicator and then logout and log back in.
Use the following command to reinstall
sudo apt-get install --reinstall libappindicator3-1 libappindicator1
If the above solutions doesn't work. Try reinstalling the network manager
sudo apt-get install --reinstall network-manager network-manager-gnome
