For home networks you do not need a bridge!
But if you want to do this, start with this information:
Network Bridge overview
Network Bridge provides an inexpensive and easy way to connect local area network (LAN) segments. A LAN segment is a single section of network media that connects computers. For example, suppose you have three computers: computer A, computer B, and computer C. Computer A has two Ethernet network adapters, and computers B and C have one Ethernet network adapter each. An Ethernet cable connecting A to B creates one LAN segment. Another Ethernet cable connecting A to C creates another LAN segment.
Traditionally, if you want a network with more than one segment, you have two options: routing or bridging. IP routing is a common solution for connecting network segments. However, to set up IP routing you either must buy hardware routers or set up the computers at the junctions between segments to operate as routers. IP routing requires difficult IP addressing configuration for each computer on each network segment, and each network segment must be configured as a separate subnet. IP routing is a good solution for large networks, where scalability is important, and where there is an experienced staff to configure and maintain the network. A bridge does not require difficult configurations, but you must purchase additional hardware bridges. Neither of these options are ideal if you have a home or small office network, do not want to purchase expensive bridging hardware, and do not have experienced staff to administer an IP routing network.
With Network Bridge, you can connect LAN segments by selecting the appropriate network connection icons and clicking Bridge Connections. Equally easily, you can enable the bridge and add connections to it. The network bridge manages your network segments and creates a single subnet for the entire network. There is no configuration required, and you do not need to purchase additional hardware such as routers or bridges. IP addressing, address allocation, and name resolution is easy to do in a single subnet IP network.
The network bridge can create connections between different types of network media. In a traditional network, if you are using mixed media types you need a separate subnet for each type of media, and packet forwarding is required for each one of the network's multiple subnets. Packet forwarding is required because different protocols are used for different types of media. Network Bridge automates the configuration required to forward information from one type of media to another.
Only one bridge can exist on a computer running Windows XP, but you can use it to bridge as many network connections as the computer can physically accommodate. For information about creating a network bridge, see Bridge Connections.
Spanning tree algorithm
Network Bridge uses the IEEE spanning tree algorithm (STA) to establish a loop-free forwarding topology. When there are multiple paths in a bridged network, loops can form and the simple forwarding rules of a bridge can cause forwarding storms, a condition in which the same frame is relayed endlessly from one bridge to another. STA provides an automated mechanism to selectively disable bridge forwarding on individual ports as necessary to ensure that the forwarding topology is loop-free. You do not need to configure Network Bridge for the spanning tree algorithm.
In todays world a Wireless Home network is best and not that expensive. Just know there are security and safe issues you need to be aware of.
There is a lot to doing this in order to do it right. I highly recommend Linksys hardware.

Setup Procedures:
Before you start you will need some important information!!!
If you are already connected, go to the command line
Start-->Run-->cmd
Type ipconfig /all
You should see something like this:
Windows IP Configuration

Primary Dns Suffix . . . . . . . :

Primary WINS Server . . . ....... . . . : Unique IP Address
Write these down or save them someplace for future reference.
If you don't see anything like this you will need to get from
your ISP.
After you have all this information and have all your hardware
connected similar to the basic diagram above you will need to
configure your Router.
Open broswer like Internet Explorer, Firefox or some such.
In the Address box type:
http://192.168.1.1
If you get prompted for a Username and Password type these,
ADMIN/ADMIN
We will change these later.
You should be take to the Setup window for the router. Use
all of the recommended settings below. They will help you
configure your router for safe wireless use and wired use in
your home.
Whereever you see something in angle brackets <...> you must
supply. When you create a new password use both upper/lower
case letters and numbers. Write it down, memorize it, eat the
paper you wrote it on and never share with anyone. Just kidding
but you should not take this lightly. Anyone who know this
information could make it so they could hijack your Internet
connection. This could have sever legal consequences or imbaracing
at the least.
