New to Linux. Installed Linus Mint Cinnamon 18.3 and it is  up and running,but my wireless is not working. I have searched the forums and done a couple things:


1) Checked driver manager - no drivers for wireless listed.

2) Ran both sudo apt-get update and sudo apt-get upgrade - still no drivers listed.

3) Ran inxi -Fz and this is what is showed:

This shows my wireless state is "down". Does that mean a hardware problem or is there a way to change it to "up"? Tried ip link set wlp2s0 up command.


Any thoughts or help is greatly appreciated.

Outside my area of expertise here, so if it's anything more complex than this I probably can't help any further, but here's a quick check you can make to see if it's just that your Wi-Fi network card is just shut down.


Click on the network icon in the bottom right corner of your screen, and choose "Network Settings"


This will open the "Networking" window.


Select Wi-Fi in the left panel.


If it says "Wi-Fi Unavailable" in the top right of the Networking window, and the toggle switch to the right of that is set to "Off", set the toggle switch to "On"


You should now be able to see a list of Wireless Networks available.


If not, then you definitely have a problem.
