Method 1: Via File Explorer

To begin with, click on Places and from the drop-down menu that appears select Computer.

service-network manager restart

nm restart

That is it. You should have successfully fixed the activation of network connection failed issue in Kali Linux. However, if you are facing any issues with the above method, try out the next workaround shared below.

Method 2: Via Terminal Window

The entire process, right from searching for the NetworkManager.conf file to changing the “managed” value, will be carried out right from the Command Window itself. Follow the below steps:

To begin with, you will have to launch the Terminal window. There are many ways of doing so, the easiest of which involves right-clicking on the desktop and selecting the Open Terminal window option.
We will now change the directory and access the NetworkManager.conf file. Type in the below command to do so:
```
cd /etc/NetworkManager
```
Next up, we will be listing out all the files of this directory via the below command:
```
ls -l
```
In the list that appears, you should see the NetworkManager.conf file. We will try and access that as follows:
```
nano NetworkManager.conf
```
Now you should see the managed=false keyword. Make the following changes:
```
 managed=true
```
Hit the Ctrl+O to save this modification, then hit Enter followed by Ctrl+X to exit.
As before, we will now have to restart the network manager. Use the below command to do so:
```
service-network manager restart
```
That is it. If you wish to check whether the connection is successful or not, we could ping a website and see if the data packets are being transferred or not. Let’s ping Google.com via the below command
```
ping google.com
```
You should now see x number of bytes being received from Google.com. This signifies that the connection has been successfully established.
