Ubuntu loves messing up!

This evening, when I reached my home and booted up my laptop I could not simply enable wifi! The option was disabled.

Last time I faced same problem, I had switched to windows 7 to search for solutions, but this time I had no other operating system installed in my machine. Also last time, I had to do nothing to solve this problem, just switching OS had automatically solved the problem. But this time, I really had to find solution. With a bit of searching, here is how my problem was solved.

Solution

# step 1: run rfkill list all
$ rfkill list all
0: phy0: Wireless LAN
	Soft blocked: yes
	Hard blocked: no
1: hci0: Bluetooth
	Soft blocked: no
	Hard blocked: no

# step 2: ublock the wireless LAN
$ rfkill unblock 0

Just running 2 commands solved the problem. Hope this will be helpful to you too.
