I am BRAND NEW to Linux, having just done a dual boot install of Ubuntu desktop 16.04 alongside Windows 10 in a new hp omen laptop. I have tried for the last several days so many different workarounds suggested in this forum to find a solution as to why the new system cannot find any wifi networks?? I am able to use a wired connection- but I need wireless. I'm guessing that my Intel card will only work on a earlier kernel, or that my particular card has no update available yet. I would be deeply appreciative for any suggestions that lead to a solution. Thank you to anyone who is willing to help!!!

  • It is not incompatible at all. Please provide the diagnostic wireless_script as described here. askubuntu.com/questions/425155/…

  • You could look in /var/log/syslog* and grep for firmware (sudo grep -i firmware /var/log/syslog*) and note if you have any firmware load failures, not followed by another successful firmware file load. If you find that, you could install linux-firmware using Synaptic, and that might fix your wireless (after a reboot). Keep us posted. Cheers, Al

  • I believe linux-firmware is installed by default in 16.04, @heynnema

This is a condensation of a lengthy chat that solved the issue.

First, there was a partially installed but not configured package on your system. We remedied this with:

sudo dpkg --configure -a

Once it ran correctly, the mis-configured package shim-signed was able to complete.

Second, You attmpted to install intel-microcode from 'Additional Drivers' but the process failed and was interrupted. Accordingly, after we verified that you indeed have Intel i7 processors, did:

sudo apt-get install --reinstall intel-microcode

After a reboot, we verified that the microcode was properly loaded.

In your pastes, there was evidence that the Broadcom driver bcmwl-kernel-source may have been incorrectly installed. We verified that it was not installed and therefore not conflicting.

Following these remedies, your wireless works!

We did notice, however, in your dmesg that the driver looks for the -17 firmware and doesn't find it, then looks for -16, finds and loads it. You might get an improvement in performance by installing the -17 firmware file. From the terminal:

wget http://mirrors.kernel.org/ubuntu/pool/main/l/linux-firmware/linux-firmware_1.160_all.deb
sudo dpkg -i linux*.deb

Reboot.
