The SB8200 cable modem is equipped with 2 Gigabit Ethernet (10/100/1000) ports on the back panel. For a typical setup with one computer, connect the Ethernet cable to the Ethernet port on the computer and to the Ethernet port 1 on the back of the SB8200 cable modem for Internet access. When there are multiple client devices in the home network, ARRIS recommends connecting the client devices to a Wi-Fi router to provide Internet access.
It is possible to connect two devices to the SB8200 cable modem. However, the cable provider must provide Internet IP Address to each device for Internet access. If both devices cannot connect to the Internet, contact the cable provider to see if they provide additional Internet IP addresses; not all cable providers will allow a 2nd address for residential services.
