Wifi not working on Broadcom [14e4:43b1] (rev 03)

If you walk the laptop right next to the router, are there still no scan results?

If there are now scan results, we wonder if both antenna wires are connected securely. If there are still no scan results, then, regrettably, I have no other suggestions aside from a new wireless card; eithe PCI or USB.

The scan was done about 2m from the router. Strange thing is, the WiFi worked (I removed Windows 8 for Linux) just fine on Windows 8. Both LiveUSB and HDD installs of Debian/Ubuntu did not work, no scan results.

I thank you for your time and effort and wish there was something that could be done to get it working. The laptop was purchased used for an employee to learn about Linux, but I will have to reinstall Windows in order to move forward.

Thanks again.

It is certainly possible to replace the wireless card in the laptop, barring a whitelist. https://www.wirelesshack.org/wp-cont...s-802.11ac.jpg As well, there are many inexpensive USB wireless devices available: https://ubuntuforums.org/showthread.php?t=2397914

In any event, I am sorry I couldn't be more helpful.

Thanks, I shouldnt give up so easily. Thanks to your linked thread, the closest USB device locally was this:

Will take a chance and see if it works!

You will need to blacklist the internal Broadcom when you install the USB. Post back if you need additional guidance.

USB adapter received. I would really appreciate help in ensuring the internal adapter is blacklisted.

Thanks!

Thanks!

From the terminal:

sudo -i
modprobe -r wl
echo "blacklist wl"  >>  /etc/modprobe.d/blacklist.conf
exit

You should be all set.

Thank you. Have blacklisted the module successfully, but with the USB adaptor connected, there is no wireless dialogue.

lsusb does show the adaptor as connected.

Any tips?
