Setting Up a Linksys Wireless Router with DHCP - CenturyLink
Connect an Ethernet cable to the "Internet" port on the back of the router.** Note: It is important to use the red cable that came with the CenturyLink™ modem. This cable should always remain connected to the CenturyLink™ modem. Next, connect the cable that came with the router (usually blue or white) from one of the numbered ports on the router to the Ethernet adapter in your computer.
