Router
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
•
•DHCP server/dynamic IP address assignment to automatically configure network and IP addresses
