Are you on a travel or is your internet connection at home not working at the moment? Are you in school and your friend wants to browse internet with you but on his phone?

Do you have an android powered smartphone with mobile internet connection?
Good! Then there is a really easy way to turn your phone into wi-fi hotspot and share your smartphone internet connection with the others around you. It's called Wi-Fi tethering.

Is it worth using LAN cable instead of Wi-Fi on your notebook/laptop? (test)

It's more and more common today that people buy notebooks instead of PCs. Because of it's portability, the place it takes to store it and probably because they simply believe that those tower cases under tables are too old-school and they believe that notebook with the same setup as desktop PC has the same power. There is also a lot of those who only use the notebook on a static place everyday.

I also bought new notebook not so long ago, altough I still preffer powerful PC with normal monitor, keyboard, mouse and speakers. I needed notebook because of it's portability. But when I'm at home, I only use it on my table next to my PC and that made me think about the sense of using Wi-Fi.
