Ethernet is available at three different speeds. 
Standard Ethernet runs at 10 Mbps, Fast 
Ethernet runs at 100 Mbps, and Gigabit 
Ethernet runs at 1000 Mbps. Most home 
networks are built using Standard or Fast 
Ethernet components. Business networks are 
typically built using Fast or Gigabit Ethernet 
components.
To create a wired Ethernet network, you or 
your electrician must install special Ethernet 
cables in your home or office.
Using a router
The most common way to set up a wired 
Ethernet network is Dynamic Host Control 
Protocol (DHCP) using a router. A DHCP 
network configuration uses a router to 
automatically assign IP addresses to each 
computer or network device. For information 
on setting up a router, see the router’s 
documentation.
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.
