Wireless routers are used to allow several computers to connect to a network via radio signals. Typically, wireless routers allow both wired and wireless connections to the network. However, if more wired connections are required than the router can support, you may choose to add an Ethernet switch to the network. Connecting a network switch to a wireless router allows the wired part of the network to expand quickly and easily.
Plug one end of the first Ethernet cable into one of the free ports on the router.
Plug the other end of the first Ethernet cable into Port 1 on the Ethernet switch. Plug one end of the second Ethernet cable into one of the free ports on the Ethernet switch.
Plug the other end of the second Ethernet cable into the computer network adapter. Open a Web browser window and type in the router’s IP address, typically http://192.168.1.1 (see Tips). If you are prompted for a user name and password, the Ethernet switch is connected properly. If not, verify that the Ethernet cable connections are snug.
