One of the most notorious solutions is to check if your notebook or pc has a WiFi switch that enables or disables the wifi. This feature by some manufacturers has baffled many, only to find all they needed to do was Hit the Button to turn it on.
Please check this first as you could easily be a victim of such a thing.
Could you please give the specs of your machine: make model and build...
Next, let's try a simple terminal command to start the wifi service and see if that jiggles the handle, so to speak:
- Code:
sudo systemctl enable NetworkManager && sudo systemctl start NetworkManager
If that fails, will need to ask you to copy this and paste in terminal, then post the output here:
- Code:
inxi -Fx
Probably needs an updated driver.
