Post by Nangabhukha » Fri Aug 23, 2019 8:19 am

TOSHIBA SATELLITE L75 BCM43142 REV 01

Just installed Mint 19.2 cinnamon on win 10 dual boot. Wif works on window 10 but not showing up on Mint 19.2
Tried 2 weeks trying various things from linux forum nothing works.

Anyone tried to make WIFI work on TOSHIBA SATELLITE L75 BCM43142 REV 01 ?

Please post an inxi -n report. This will give us a concise overview of your network hardware and on how Mint sees it.

Here is how to generate the report and post it:

Open a terminal window. Make it fullscreen to avoid unneeded linebreaks or chopped lines. Execute the command

Code: Select all

 inxi -n 
exactly as it has been typed here.

Mark the complete text output which the command will display with your mouse.
Press the keyboard shortcut <Shift><Ctrl>C to copy the marked text into the clipboard.
Enclose the results between the code markers by selecting </> from the mini toolbar above the textbox where you type your reply then paste <Ctrl>V them in your reply between the code markers.

The results will help us to help you.

First, go into your Bios and make sure Secure Boot is disabled.

Then, check out viewtopic.php?f=53&p=1608164 and follow instructions there.

1) I performed clean install of mint 19.2 dual boot with window.

2) Selected the driver suggested by update manager.

3) DISABLE the secure boot.

4) reboot the system and wifi started working.

Most likely the issue was secure boot

Thanks for all your help Larry
