I'm in the process of replacing my old $7/month rental modem/router from Comcast with a Motorola Surfboard SB6141 modem. My plan is to have a fairly basic system set up as follows: cable line > modem > ethernet line > Time Capsule > ethernet line > Ooma Telo VoiP, with the Time Capsule providing WiFi. I'm having problems at the Time Capsule stage (so forget about the Telo for now). This setup was working fine to get me online: Comcast cable > Surfboard modem > Ethernet cable > iMac But when I introduced my Time Capsule between the modem and iMac, I got a blinking yellow light on the Time Capsule. The Airport Utility indicated two status alerts — “Internet connection” and “No DNS Servers.” After that, I unplugged both the modem and the airport, connected them via Ethernet and restarted them. This produced a steady green light on the Time Capsule and no status alerts in the AirPort Utility … but in the Preferences>Network pane, my Wi-Fi has a yellow light and a note that it has a self-assigned IP address and will not be able to connect to the internet. (BTW, earlier in the day I called the cable company and gave them the Surfboard's Mac # ... the cable rep said everything looked fine on his end.) Can someone walk me through what needs to be done to get this up and running?
