See if any of the information here helps you out:

Is power management turned on as shown in this output:

iwconfig

Then you might want to turn it off to fix wifi issues:

sudo sed -i 's/3/2/' /etc/NetworkManager/conf.d/default-wifi-powersave-on.conf

Check BIOS and see if there is a Secure Boot setting, I think the mokutil program isn't correct

Let's try to silence that wireless chipset error:

Open a Terminal window (Ctrl-Alt-T), then copy-and-paste the following command-line...

Code: Select all

cd /lib/firmware/brcm;sudo wget https://github.com/winterheart/broadcom-bt-firmware/blob/master/brcm/BCM43142A0-04ca-2006.hcd

Reboot.

I thought it might be secure boot also.

Did you look in Bios to see if you can find & disable secure boot?

sleeper12 · Post by **sleeper12** » Sun Jun 06, 2021 2:40 am

Is Bluetooth maybe blocking your wifi from working?

infinito1971 · Post by **infinito1971** » Sun Jun 06, 2021 2:52 am

Hi sleeper12,
in my pc bios there is no option related to secure boot.
Also, I think bluetooth doesn't blocks wifi.

Too long without an inxi System Information+ report. With your laptop online by tether or otherwise:

Open a Terminal (Ctrl-Alt-T), click CODE:SELECT ALL, then copy-and-paste the following as one block of text into the Terminal window...

Code: Select all

After a pause, a termbin.com URL will appear in the Terminal window. Paste that URL into a reply.

A couple of things to try:

Boot into Windows, then disable Fast StartUp in power options: How to Turn Off Fast Startup in Windows 10 (1m53s @YouTube)

Also, open a Terminal (Ctrl-Alt-T), click CODE:SELECT ALL, then copy-and-paste the following as one block of text into the Terminal window...

Code: Select all

sudo modprobe -rv bcma wl && sleep 5 && sudo modprobe -v wl;\
sudo sed -i 's/3/2/' /etc/NetworkManager/conf.d/default-wifi-powersave-on.conf

Reboot.
