Introduction

Are you tired of dealing with the annoying airplane mode on your Ubuntu 20.04 system? Do you want to remove it permanently and enjoy seamless connectivity? Look no further! In this article, we will guide you through the process of permanently removing airplane mode from Ubuntu 20.04.

Understanding Airplane Mode

Airplane mode, also known as flight mode, is a feature that disables all wireless communication on your device, including Wi-Fi, Bluetooth, and cellular connectivity. While it's useful for conserving battery life or preventing distractions during flights, it can be frustrating when you need to access the internet or connect to a network.

Why Airplane Mode Persists on Ubuntu 20.04

As you mentioned, disabling Wi-Fi before going into standby or hibernating is required to prevent the internal PCI Wi-Fi from dying upon waking. This is a known issue with the iwl3945 driver, which is not fixed in Ubuntu 20.04 LTS. However, this issue is not directly related to airplane mode. Instead, it's a separate problem that requires a different solution.

Removing Airplane Mode from Ubuntu 20.04

To remove airplane mode from Ubuntu 20.04, you'll need to edit the system configuration files. This process requires root privileges, so make sure you have the necessary permissions.

Step 1: Edit the System Configuration Files

Open the terminal and run the following command to edit the system configuration files:

sudo nano /etc/NetworkManager/conf.d/10-globally-managed-devices.conf

This will open the file in the nano editor. Add the following line at the end of the file:

[connection]
wifi.scan-rand-mac-address=no

Save and close the file.

Step 2: Edit the Network Manager Configuration File

Next, you'll need to edit the Network Manager configuration file:

sudo nano /etc/NetworkManager/system-connections/your-connection-name

Replace "your-connection-name" with the actual name of your Wi-Fi connection. Add the following line at the end of the file:

[connection]
wifi.scan-rand-mac-address=no

Save and close the file.

Step 3: Restart the Network Manager Service

Restart the Network Manager service to apply the changes:

sudo service network-manager restart

Step 4: Verify the Changes

Verify that the changes have taken effect by running the following command:

nmcli connection show

This will display a list of all available connections. Look for the "wifi.scan-rand-mac-address" property and verify that it's set to "no".

Conclusion

Removing airplane mode from Ubuntu 20.04 requires editing system configuration files and restarting the Network Manager service. By following the steps outlined in this article, you should be able to permanently remove airplane mode from your system. Remember to verify the changes by running the nmcli connection show command.
