Example router-based Ethernet network
The following is an example of a wired Ethernet network. The network is made up
of a router, a cable or DSL modem, your computers, and cables connecting each of
these components. The router is the central control point for the network.
Tip
To add the ability to access a wireless Ethernet network to your wired
Ethernet network, connect an access point to the router or use a router that
has a built-in access point.
Attached to the router are all of your computers or Ethernet-ready devices. Also
connected to the router is a cable or DSL modem that provides access to the Internet.

Equipment you need for a router-based Ethernet network
Important
For best results, all Ethernet components should be either standard
Ethernet (10 Mbps), Fast Ethernet (100 Mbps or 10/100), or Gigabit Ethernet
(1000 Mbps or 10/100/1000). A mixture of components rated at different
speeds will result in your network running at the speed of the slowest rated
component .
For a wired Ethernet network you need:
Two or more computers with Ethernet jacks
•
One router
•
One broadband Internet connection (optional)
•
Ethernet cables connecting all of the network equipment
•
When buying your router, be sure the model includes everything your network needs,
including:
Internet security features, such as a firewall, to protect your network from
•
unwanted intruders
4-port switch to eliminate the need for additional network hardware
•
DHCP server/dynamic IP address assignment to automatically configure network
