Are you in a PPPoE area, or a DHCP area? If PPPoE, you need to get your PPPoE username and password from CL and enter it on the WAN setup screen in the Linksys router. If DHCP, reset the Linksys to factory defaults and connect it to the router. It should pull a public IP. Also, do an IP release in the modem before switching it to bridge mode. Once the modem achieves DSL sync, boot up the router and you should have internet access. Check the status page in the router to make sure you are getting a connection to the CL network.
