A:Answer Unfortunately, no, you cannot. This modem only allows for 1 ethernet connection. The additional ports are for connecting a port bonding router, so that you may exceed speeds of 1 Gbps, and ISP's haven't offered this service as of yet to consumers. It's still a good thing, as when technology allows, your modem will already be setup for it. To connect your devices, your only option is to connect a router to the 1 ethernet port on this modem, use the router's additional ethernet ports, or connect a wireless router to the 1 ethernet port and then connect your devices to your wireless router's network.
