Cable and DSL modems often lack multiple Ethernet out connections, instead relying on the end user to purchase components such as a router to connect multiple computers. A wireless router can be used to connect both WiFi capable devices and wired network devices to a single internet connection. Connecting multiple routers to one modem is also possible.

Step 1

Connect the wired end of the Ethernet splitter into the "Internet Out" or "To Computer" jack on the back of the modem. You can view an example of an Ethernet splitter in the Resources section of this article.

Step 2

Connect one end of each Ethernet cable into each of the splitter's jacks.

Step 3

Connect the other end of one of the Ethernet cables into the "Connection In," or "Internet" jack on the back of one of the wireless routers. Connect the end of the second Ethernet cable into the same jack on the second wireless router.

Step 4

Plug in the power supply of the modem. Wait for the modem status lights to turn on and plug in the power supplies of each of the wireless routers.
