[SOLVED] Can't use wifi

Post by girlggc » Thu Apr 09, 2015 8:25 am

I'm at a loss. I've been using Linux successfully for quite some time now so I probably should know how to fix this problem but, alas, I do not. Anyway, up until yesterday my wifi was working fine. Now it won't work. The icon is not appearing in the system tray. Wired Ethernet does work, though. I am running Linux Mint 17.1 Cinnamon 64-bit on a Dell XPS 15 L521x, if that matters.

Please generate an overview of your system like this:
- launch a terminal window and make it fullscreen, to avoid chopped lines;
- copy/paste this command into the terminal:

Code: Select all

inxi -Fxz
if you type: the letter F is a capital letter

Press Enter.

Copy/paste the output in your next message.

Also post the output of this command:

Code: Select all

sudo rfkill list all
And of this command:

Code: Select all

iwconfig

Apparently, there's absolutely no wireless chipset to be found at all.... :shock:

Unfortunately, I'm at a loss. Hopefully someone else can help you.

Check BIOS to see if wifi is enabled, if it is enabled or there is no option to disable, power off the computer then remove and insert the wifi card

I just checked the BIOS and there is no option to disable. I'll reseat the wifi card later on when I'm not at work.

Is there a physical switch or button to turn off the wifi? Maybe it has been accidentally switched off? I know I've done that before.

I forgot to update. I reseated the wifi card and that did the trick.
