It is also used to distribute a single Internet connection to several computers.

  1. 1

    Plug one end of an Ethernet cable into the "Internet" port of the modem and the other end into the "Ethernet" or "Line In" port of the Ethernet switch.

  2. 2

    Connect one end of the second Ethernet cable from the first numbered port of your switch and the other end to the "LAN" (Local Area Network) port of your computer. Connect another Ethernet cable from the second numbered port of the switch into the LAN port of the second computer. Continue connecting each computer.

  3. 3

    Plug the switch's power cable into a working power outlet. Turn on the computers connected in the network and open a Web browser to see if they can detect the Internet connection. If the computers cannot detect Internet connection, there may be a problem with the Internet connection itself, with the modem, or with the Ethernet switch.

  4. 4

    Call your Internet Service Provider to make sure the problem is not with the Internet connection. If there is no problem with the Internet connection, reboot the modem to refresh the connection. Connect one end of an Ethernet cable from the "Internet" port of the modem while connecting the other end to the LAN port of one of your computers. If the computer detects Internet connection, the problem may be with the Ethernet switch. If you just purchased the device, return it to the store to be replaced.
