[SOLVED] Wifi Device marked unclaimed in Dell Inspiron 3521

jmpilon · 04-16-2017, 08:13 PM

I installed Elementary OS Loki on my Dell Inspiron. The wifi does not work.

I do not see Wireless under devices in the System Settings>Network.

Any suggestions?

Code:

sudo lshw -C network

Hello and welcome to the forum

Take a look at the solutions mentioned here. One of those might resolve your issue. If not, please open a terminal and run the following commands...

Code:

wget -N -t 5 -T 10 https://github.com/UbuntuForums/wireless-info/raw/master/wireless-info && \
chmod +x wireless-info && \
./wireless-info

Then navigate to the location of the text file the script created and post the entire contents (or a link to them) in your next reply.

Probably just need firmware installing for it.

I figured it out. My secure boot was on. Even when I installed the drivers below, and it prompted me to turn off Secure Boot and create a password, it never prompted me for that password on restart. So I went into BIOS and removed the Secure Boot and then the wifi was working.

Thanks for your help and assistance!

Cheers

Code:

sudo apt install bcmwl-kernel-source
