Example router-based Ethernet network
The following is an example of an Ethernet network. The network is made up
of a router, your computers, and cables connecting each of these components.
The router is the central control point for the network. 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.
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, such as the Linksys wireless
access point router with 4-port switch.
Equipment you need for a router-based Ethernet network
For an Ethernet network you need:
Important
For best results, Ethernet network
components should be either all
standard Ethernet (10 Mbps), all Fast
Ethernet (100 Mbps or 10/100), or all
Gigabit Ethernet (1000Mbps 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.
■ Two or more computers with Ethernet jacks
■ One router
■ Ethernet cables connecting all of the network equipment
■ One broadband Internet connection (optional)
Tips & Tricks
When buying your router, make sure that
the model includes everything your
network needs, including
Internet security features, such as a
firewall, to protect your network from
unwanted intruders,
a 4-port switch to eliminate the need for
additional network hardware, and
DHCP server/dynamic IP address
assignment to automatically configure
network and IP addresses.
