If you are like me, an expatriate who does not want the hassle of installing a broadband Internet in a rented room, this video will thrill you. However, bear in mind that it is illegal in some countries such as Singapore to use third party Wi-Fi connection without consent. You have been warned.
The video by Infinite Solutions shows you a method of boosting Wi-Fi signal by two bars. If you have a 3G phone, you just need to wind an LAN cable (Ethernet cable or CAT5 cable) around the phone. The mobile phone has a better ability to grab a weak signal than most Wi-Fi antenna in an electromagnetic noisy environment such as your room or house full of electrical appliances.
