I have Asus G46V laptop running Ubuntu 18.04.3 LTS and when I open WiFi settings, I get this message: No Wifi adapter found

I tried this solution and this one but with no luck.

Here is my network card: 03:00.0 Network controller [0280]: Broadcom Inc. and subsidiaries BCM4352 802.11ac Wireless Network Adapter [14e4:43b1] (rev 03) Subsystem: AzureWave BCM4352 802.11ac Wireless Network Adapter [1a3b:2123]

Here is the output of iwconfig:

$ iwconfig
lo        no wireless extensions.

enp4s0    no wireless extensions.

and here is the output of lspci -nn -d 14e4::

$ lspci -nn -d 14e4:
03:00.0 Network controller [0280]: Broadcom Inc. and subsidiaries BCM4352 802.11ac Wireless Network Adapter [14e4:43b1] (rev 03)

I then tried:

sudo apt update
sudo update-pciids
sudo apt install bcmwl-kernel-source

then sudo reboot, but with no luck.

Then, following this question I removed the installed driver using sudo apt-get purge bcmwl-kernel-source. I then installed sudo apt install firmware-b43-installer then

 sudo modprobe -r b43
 sudo modprobe b43    
 sudo rfkill unblock all  

but stil having No Wifi adapter found

As a side note, a bought a TP-Link AC600 Archer T2U Nano wifi USB dongle but it is also not working. Here is the question where I try to look for a solution.

I very much appreciate your help.


Edit 1:

I reinstalled bcmwl-kernel-source and here is the output of $ lspci -knn | grep Net -A3; rfkill list

:~$ lspci -knn | grep Net -A3; rfkill list

This problem looks like some kernel bug. The wl kernel module is not loading for some reason.

Try out if it has been fixed by updating your system by running:

sudo apt update && sudo apt upgrade

  • Awesome! Glad it's working now. I suspect that the Broadcom will outperform the USB. – chili555 Feb 3 at 21:26
