Oops, something has gone wrong. Please contact your software vendor. Network Manager needs to be running,no WiFi adapter error in Kali Linux [Solved]

Oops, something has gone wrong. Please contact your software vendor. Network Manager needs to be running this is the error message i got in Kali Linux. Currently, Wi-Fi is disconnected, not working / not visible in settings icon too, system says no wifi adapter found (which worked fine before that) when network manager service was restarted, any idea on how to fix this bro ?, i'm running Kali Linux latest version ! asked one of our blog reader (who seems to be newbie to linux world). 

So, i decided to write a separate post on this. If you are experiencing this same issue (WiFi not working or missing on settings icon] then i hope this post might help you too.

Oops, something has gone wrong. Please contact your software vendor. Network Manager needs to be running, no wifi adapter found error in Kali Linux [Solved]

Hmm, i will share the solution with my personal experience. I was also once a learner and new to Linux world. In order, to learn fast i tried experimenting few things like running multiple commands at once (i tried to do a kinda of scripting, which ofcourse went in vain). Result ? some how My WiFi got disabled. When i opened Settings icon and clicked on WiFi option now it says, " Oops, something has gone wrong. Please contact your software vendor. Network Manager needs to be running" I was like ok, network manager needs to be running right? so let's start network Manager. 

I opened terminal, and ran service network-manager restart as root. Now i got added problem. After running the above command now, my WiFi option was gone, it was missing from the settings. I did searching for it and Finally found the option but this time one more greeting from my Kali linux machine "No WiFi adapter found" Make sure you have a WiFi adapter plugged and turned on" i was little bit shocked and thought "Ok, Congrats we had successfully disabled the WiFi adapter on hardware level", now what? do i had to break the laptop and open the trays/circuits, to find missing WiFi device or write some coding to restore the Wifi services? no way! i tried to recall all the things i did but nothing worked. Finally i tried one crazy idea the monitoring WiFi networks around me and surprisingly i found the solution with that, because the device successfully scanned and listed the WiFi networks around me. With now, i found the rootcause, which is nothing but the WiFi being in monitored mode, i got back the WiFi.

Here, is what you have to do...

Open terminal as root by elevating permissions and stop the airomon-ng monitoring mode/service.

I.e; Open terminal and type sudo airmon-ng stop (Your WiFi interface name)

Example :  sudo airmon-ng stop wlan0

Make sure, you replace Wlan0 with your interface name. It might be Wlan0 on Some systems, and Wlan0mon on most of the systems. You can find your WiFi interface name on ifconfig and it failed try looking for the previous commands that you ran on the terminal.

After running that command, now restart the network manager. 

i.e.; Service network-manager restart

Now, go back to settings and see your WiFi will be there, which means our WiFi device was restored. 

-There is nothing wrong in breaking things, that's how you will learn new things :)

Happy breaking :)

Okay so hypothetically speaking, say you have the same situation with network manager, except ypu dont have any of the packages that run ifconfig, or airmon-ng. And cause theres no internet you cant apt-get install them. What exactly needs to happen.
