When setting up a network at home, you could use a CAT 5 cable and lay it on the floor. That can be very messy. Alternatively, you could use a Wireless Router.
Although it is easy to set up a wireless router to connect your PC and router, it is sometimes difficult to get a proper reception because your PC and router might reside in different rooms.
These two methods are quite problematic as you need to lay new cables or need to align your antenna to get proper reception.
Aztech Homeplug solves this issue by using the Power Plug at home for your in house networking. Now you get better reception and you do not need to rewire your house. Most importantly, you don't get drop packets and the speed is remarkable.
