similar posts have been found. but, related 12.04, not 16.04. and, no solutions offered anyway.

i suspect may related problem running hot , on "battery" when ac attached. but, honestly, lost.

any appreciated.

thank you.

you loading defective -16 firmware. why don't download -17 firmware newer and, in experience, better? terminal:

wget http://mirrors.kernel.org/ubuntu/pool/main/l/linux-firmware/linux-firmware_1.161_all.deb sudo dpkg -i linux*.deb 

reboot , test.

you might see if f2 light, led actually, performs correctly after this:

sudo -i echo "options iwlwifi led_mode=1"  >>  /etc/modprobe.d/iwlwifi.conf exit 

reboot , test.
