Example router-based Ethernet network
The following is an example of an 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.
Tips & Tricks
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 an 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 and IP addresses
