I’ve noClue what your problem is or might even be, but …

I need to shutdown and start system to get wifi back.

… no, you don’t.

One of those commands …

sudo ip link set wlan0 down
sudo ip link set wlan0 up

or

sudo ifconfig wlan0 down
sudo ifconfig wlan0 up

… should be able to restart the WiFi interface.

Unfortunately these commands failed to restart wifi.Restart networking or networkmanager also fails to get wifi back.Shutdown and start system only works.

As Wi-Fi is working upon restart, it’s probably not a HW damage, all through it might be some quirk like the one I had once with one of my Windows machines: Wi-Fi driver entered a sleep mode and never waked up. Yeah, Windows is screwed, but Linux even much more so …

Three ideas …

1. Restarting WiFi interface didn’t help …

2. Restart networking:

sudo /etc/init.d/networking restart

Or — first stop it and then start it again:

sudo /etc/init.d/networking stop
sudo /etc/init.d/networking start

3. Reload a driver:

That one is not that easy … first you’ll have to find out some specs about your PC:

inxi -F

‘Network’ part of output will give you some idea about your HW.

Afterwards, you’ll have to find which exact driver is striking and reload it manually as described here:

If it still doesn’t work, change the OS or the PC …

What happens once, might happen again and that’s not what one computer is supposed to do — be unreliable.
