On this system, the airplane mode indicator is always on. fn+f2 does nothing.

The light under the key stays on.

Toggling airplane mode to "ON" in settings DOES turn the light off and disables wifi.

dmesg | grep iwl reveals that the... well, see for yourself.

Similar posts have been found. but, related to 12.04, not 16.04. And, no solutions were offered anyway.

I suspect that this may be related to another problem with always running hot and on "battery" when AC is attached. But, honestly, I am completely lost.

Any help would be appreciated.

Thank you.

loaded firmware version 16.242414.0 op_mode iwlmvm

uCode file size 36723 does not match expected size

You are loading defective -16 firmware. Why don't we simply download the -17 firmware which is newer and, in my experience, better? From the terminal:

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

Reboot and test.

You might see if the F2 light, an LED actually, performs correctly after this:

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

Reboot and test.

  • Didn't know hitting enter would close the darned reply box... Anyway, we got the -17 driver loaded. THANK YOU! Hopefully that will give me a bit more "AC" speed. But, it appears that my theory was wrong... The F2 light is still on. And, the "running on battery" is likely a separate issue. Any suggestions? – Orian Oct 23 '16 at 13:41
  • Yes, it's likely unrelated. I suggest you open another question with details about it. –  Oct 23 '16 at 14:13
  • I think the F2 light might be related. Please see my edit above in a few moments. – chili555 Oct 23 '16 at 16:01
  • Unfortunately the conf edit didn't change the F2 light problem... Thank you for the reply. – Orian Oct 23 '16 at 23:28
  • (CelticWarrior) I had posted separately, regarding the battery issue a couple of weeks ago. The post has received no replies to date. I began to think (hope) they were related issues. – Orian Oct 23 '16 at 23:30
