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.

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 (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.

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,

a4-port switch to eliminate the need for additional network hardware, and DHCP server/dynamic IP address

assignment to automatically configure network and IP addresses.
