SecureBoot enabled

[sleeper12]

Disable secure boot in Bios & see if wifi works then.

[rezak400]

Thank you for the reply, I just disabled secure boot option to disabled on the bios, but now after i turn on the laptop and linuxmint logo show up, my screen turn black and nothing happen, like freeze on black screen

[sleeper12]

Can you boot back up if you enable secure boot again?

[rezak400]

Yes, i just do that, and it came normal again, but still, its cannot detect wifi

[sleeper12]

It might help to update your kernel to 5.4.0-72.

I just fresh install linux mint 20.1 XCFE on my Acer Laptop, and it cannot detect wifi, it was fine before on windows, i try several on solution on forums but none of that works,

Via smartphone tether or other connection, launch Driver Manager so it can search for a wifi driver. Accept whatever driver it recommends.


Otherwise, try this:

On your Acer, open a Terminal window (Ctrl-Alt-T), copy-and-paste the following command, then tap Enter...

Code: Select all

sudo apt install -y broadcom-sta-dkms

Reboot your Aspire.

[sleeper12]

If you have the new kernel, see if you can boot up now with secure boot disabled.

[rezak400]

I follow your intruction and use the kernel, but after i do disabled secure boot, its still black screen like before, and still cannot detect wifi network

I already do the driver manager recommend, and try your install driver too, but its still cannot detect wifi network

[sleeper12]

Are you dual booting with windows? If so, you might need to disable fast boot also.

[rezak400]

No i dont do dualboot, i fully install my laptop with linux which is format the disk

[sleeper12]

Well, I suspect that secure boot is blocking your wifi which is why it should be disabled. But, I don't know what is causing the black screen. Maybe someone else will know how to fix that problem.

[rezak400]

Thank you very much once again, ill try to loo solution for that

Does Driver Manager also not recommend a driver for your nVidia GeForce graphics? You're running nouveau.


Open a Terminal window (Ctrl-Alt-T), then copy-and-paste the following 3 command-libes, one by one...

Code: Select all

sudo wget -nv -t 5 -T 10 https://github.com/UbuntuForums/wireless-info/raw/master/wireless-info -P /usr/local/bin/
sudo chmod +x /usr/local/bin/wireless-info && cd ~/Downloads
wireless-info >/dev/null && tr -cd '\11\12\15\40-\176' < wireless-info.txt | nc termbin.com 9999

After a pause, a termbin.com URL will appear in the Terminal. Copy that URL in a reply hear.

Can you boot your Mint installation USB/DVD okay with Secure Boot disabled? If so, consider installing Mint with Secure Boot already disabled.

Also consider upgrading the BIOS, since the flashing process may do a deep reset of sorts.
