Airplane Mode

Hardware Support
#1

Hi
I am new to Linux, I noticed that the airplane mode is on and all the switches are grayed out. I have tried every terminal command that I could find but nothing seems to work? I have looked into the wifi and it says shut off airplane mode, however, since the switches are grayed out I can't do anything. Any thoughts and is there a program I can install to troubleshoot this problem?

Thank You
Vinny

Try wireless - Turn Airplane Mode on/off via terminal - Ask Ubuntu

Hi carmar
I went to the site in the link, however, nothing worked? When I try to turn the wifi on for a split sec I see the wifi screen then the airplane symbol appears for some reason it will not allow me to shut the airplane mode off. I even tried signing into the system as a root user.

You mentioned using every terminal command you could find.
Did you use rfkill? Modprobe?

#5

Hi Aravisian
I did try using rfkill even as a root user. What is Modprobe?

#6

Module Prober.

Can you please post the output from terminal of:

sudo lshw -c network

#7

Hope this helps you?

This driver should be fully working in the Kernel. And given that you seem to have no control in the software...
Many Notebooks, etc. have a Physical Switch for the Airplane Mode or Wifi.
It may not be obvious; sometimes it is a FN-Key combo from the keyboard.
Have you thoroughly explored this, yet?

When I use the Fn F5 key I get a message that says Hardware Airplane Mode
it seem after using the key nothing happens? It does not shut it off or on?

#10

Ensure you do not continue holding the fn key...

You may also try running it from tty (as this is like safe moding it).
Use ctrl+alt+F7 to Exit (remember this!) from the tty.
Use ctrl+alt+F3 to Enter TTY.
Enter your username and password, then use the keyboard shortcut to disable Airplane mode.

Also - in BIOS is Secure Boot disabled or Enabled?

#11

Hi Aravisian
OK, this is a little over my head, question do you know if there is a diagnostic tool out there that maybe I could use. For now, I can still get on the internet by my cell with a direct with USB Tethering

#12

None other than the GUI Network settings that comes with Zorin OS.
However, I am quite confident you can follow the above steps. You can use the ctrl+alt+F3 keyboard combo to enter tty. Enter your username and password. Then use the Wifi / Airplane mode keyboard shortcut you mentioned above; Then exit tty with ctrl+alt+F7.
Believing in yourself is the first step toward independence.

Enter grub and switch to kernel 5.11.0-40

UEFI hold the escape button during boot
Legacy bios hold the schift key during boot

Yesterday i got another user that could not use the wifi anymore after updating to 5.11.0-43

That last kernel gives regression to some users

Hi Michel
Sorry I am very new to Linux. Could you be more detailed with your instructions? You are correct. This happen after I received a major update the other day.

#15

I thought i was clear, but i explain it a bit better

  1. Reboot machine
    1a. If you have a UEFI machine hold the escape button during boot to enter grub
    1b. If you have a Legacy bios hold the shift key during boot to enter grub
  2. When you are in grub press advanced mode
  3. Select kernel 5.11.0-41 (the normal one, not the recovery)
  4. Check if the problem is gone, if yes open up terminal and write this
sudo apt-get purge linux-image-5.11.0-43-generic

sudo apt-get purge linux-headers-5.11.0-43-generic

Hi Michel
Thank You for clarifying the process for me, I have the Legacy bios and proceeded as you asked. However it has not worked? Any other ideas that I may try? Something I noticed when getting into the Legacy bios I noticed two different choices one was Zorin, with Linux 5.11.0-43-generic and the other was Zorin, with Linux 5.11.0-41-generic The other thing I noticed was both UEFI and the Legacy worked to get to the same screen?

#17

Did you try that one or the 5.11.0-37 one ?

#18

Hi Michel
Yes at this point why not. Neither one of the choices worked? Any thoughts!

#19

Hi Michel
Sorry, I must be loosing it, I do not have one that is Linux 5.11.0-37?

#20

Can you post a photo of that menu, easier to talk :grinning:
