If you use your laptop in multiple places you may know how hard it is to keep changing network settings over and over again. For example you may use the laptop at your home, office or even at your local start bucks coffee shop. Every time you go to a new place there is a new network configuration you have to setup.
This gets quite tedious over time and specifically when you have to setup a manual IP (Internet Protocol) address to access the Internet connection. I definitely have had a lot of problems earlier when I was in India as neither my office nor my home connection used DHCP (Dynamic Host Configuration Protocol) which automatically assigns dynamic IP address to your PC.
The switch from home to office had to be done manually so that I could use the Internet at both places. Well as you may already see how boring and tedious it is to switch between different network setups.
