Running two routers off of one cable Internet connection allows you to do many things including increase the number of computers at your business that you can connect to the Internet or set up more than one wireless network if you have two wireless routers. Using a network with two routers makes sense in a small business when you run out of ports on a first router to connect computers or devices to. Setting up the two routers is a fairly straightforward process and should only take about an hour.
Step 1: Attach the coaxial cable coming into the building which provides Internet access to your cable modem's coaxial connector. This is necessary if your modem is not already installed. If it is already set up go on to step 3. Attach the power adapter to the modem and turn it on.
Step 2: Call your Internet service provider and provide them with the serial number and MAC ID of the router if prompted in order for the modem to be activated.
Step 3: Connect one side of an Ethernet cable to the Ethernet port on the modem. Connect the other side of the Ethernet cable to the WAN or modem port on the first router.
Step 4: Reset the router by pressing and holding the reset button with a paper clip for thirty seconds. It is easier to start out with the default settings for the router so you can follow the steps to set it up in the router's documentation.
Step 5: Power on the first router. Attach an Ethernet cable from one of the LAN ports on the router to the Ethernet port on your computer.
Step 6: Open your Web browser on your computer and enter the default IP address of the router. This can be found in its documentation. Follow the steps to log in and set up your router from its documentation.
Step 7: Reset the second router as you did previously with the first one by pressing and holding the reset button for thirty seconds. Attach an Ethernet cord from a LAN port on the first router to the WAN or modem port on the second router.
Step 8: Power on the router. Attach your computer to a LAN port on the second router using an Ethernet cable.
Step 9: Open your Web browser and go to the IP address of the second router. Follow any steps to finish setting it up as found in its documentation.
