Many homes and businesses are being built today with networking in mind. Homes are now built with category 5e cabling and are ready to go in terms of setting up your home network to provide Internet or let you share files and audio visual material.

However, in older homes and offices this is often not as easy. Depending on the structure it could be difficult to install category 5e cabling, and if the walls are thick or metal wireless coverage can become a problem.

There is a third option that has been coming up in the news lately called powerline networking. This technology has been around for some time, but recently new devices being developed to allow high speed data transfer have been emerging into the market and are now common and easy to find.
