Wireless networking is extremely
popular for building a home network, but wireless isn't the only
way to go, both wireless and wired home networks have their own
distinct advantages
Advantages of Wireless Networking

Portable & Flexible: Wireless
networking devices enable you to use your computer, laptop or
games console anywhere in the house. Even if you have a large
house, wireless signal will generally go through walls
and ceilings. If you need to go extended distances you can use
access points to boast the wireless signal. A wireless network
can reach speeds up to 54Mbps (Mega Bits Per Second)
Cost Effective: With the price
of wireless equipment dropping and the labor saved of not
running cable Both methods are comparable.
Neat & Safe: If you choose
to set-up a wireless home network you do not need to run cables
across your house, which can create trip hazards across rooms,
hallways and stairs. Also choosing to set-up a wireless home
network means that you do not need to run cables underneath
carpets or drill holes through walls or ceilings to pass cables
through.
Advantages of Wired Networking

Faster: Wired connections can
reach networking speeds of up to 10 times that of wireless
networks, which is necessary for bandwidth hungry users
such as avid gamers, graphic designers or users downloading
large media files. However, for most users the standard
100Mbps networking speeds are more than sufficient for everyday
networking activities such as: Emailing, surfing the web,
downloading files, music and video, accessing corporate
information and playing console games.
Reliable: Physical, fixed wired
connections are not prone to interference and fluctuations in
available bandwidth, which can affect most wireless networking
connections.
Secure: With a wired network you
don't have to worry about your networking signal traveling
through the air and being interrupted by eavesdroping
Neighbors or hackers driving around trying to find wireless
hotspots.
