If you have very old phone wring, then there may be performance problems. The phone line system is easy to install and does not interfere with the normal use of your phone. The Phone Line Network is about as fast as the traditional wired network. If you have computers with USB ports on them, there are Phoneline Network adapters that will connect to via the USB port. The third method is a wireless Home Computer Network.
Wireless technology offers ease of installation and no wiring to worry about.
The Wireless network will allow you to roam to almost any room in your house using your laptop computer. Because of the higher frequency, metal objects or even some walls can block the radio signals. As the signal level deteriorates, so does the speed. Wireless networking can often be the answer to a difficult Home Networking situation or if you have a need to roam with your portable computer. For now, it appears the best bet for an inexpensive way to get a home network going is the wired CAT5 kits or the Phoneline Network.
