What fixed it 

New driver from: https://www.intel.com/content/www/us/en/support/articles/000005511/wireless.html

cd /lib/firmware
tar xzf iwlwifi-6000-ucode-9.221.4.1.tgz
cd iwlwifi-6000-ucode-9.221.4.1
cp iwlwifi-6000-4.ucode .

What was wrong? It needed a new device driver from Intel (thanks Intel!) and the renaming had to be shut off (thanks https://forums.linuxmint.com/viewtopic.php?t=303841)

This took many hours - I hope you find it helpful. :)
