Dear Christopher, thank you for answering and pointing out the old bios version.
I've updated the BIOS to the latest version and tried again with both kernels and firmware. The result didn't change, thus the wireless is still not working correctly. As you requested this is the output that confirms the correct bios update. sudo dmidecode -s bios-version && sudo dmidecode -s bios-release-date GMET68WW (2.16 ) 11/07/2014 What are the next steps?
