Q: Having trouble getting Time Capsule/Airport to connect to new Comcast Internet service
Ok let first start off by saying that as good as I am with computers, Networking ***** and I suck even more at it. With that being said, I'm having a lot
Of trouble with my Time Capsule. At least the airport part of it anyways. We just got Comcast Internet hooked up this morning and the guy that came over said I har Internet on my main computer, I just need to redo the setup on my airport and I'll be good to go. So I thought cool that's simple enough to change it back to default settings and just go through the process of setting it up again....WRONG! I go through the setup and first of all I have no idea what the difference between "Bridge Mode" and the other option but since I never use bridge mode, I just went with the other option. However, once I complete the setup, I have the flashing amber colored light and airport is saying I have two problems one is about "Internet Connection" and the other is for "No DNS Servers". At this point, my wireless devices can see the wireless network I've setup but there's not actual Internet to do anything. However, my main compute that's connected by Ethernet to the modem can connect just fine. So I decided to do a power cycle on everything. All the connections are correct and so I turn it all back on and I still have the same problem with the airport but now my main computer can't connect to the Internet anymore. Needless to say I got frustrated and had to leave for work. So my question is how do I resolve this and get my Internet connect and airport up and running properly? If someone. Luke just break it down to me step by step to the level of a 10 year old that would really help as I mentioned before I'm really terrible when it comes to networking. Any help is appreciated!

... it has to be the time capsule having the issue cause if I take that out and connect my computer straight to my modem, there's no issues connecting my main computer to the Internet. But once I connect the time capsule, then my main computer loses Internet connectivity as well...hope that's a clue..
Yes, that's a clue. Whenever you disconnect anything from the modem, power it down and let it reset. A moment or two should be sufficient, but I have heard anecdotal reports of some that require longer, in one case it was overnight. Some even have a battery backup or tiny reset switch, and I'm not sure which your RCA has.
The idea is to get it to "forget" the device with which it last communicated. Your modem supplies one and only one IP address. It needs to supply it to the Time Capsule, and it's not receiving it.
Another remote possibility is something called "ISP provisioning" that may require your ISP's intervention to fix. I doubt this is the case but it does describe the trouble you are experiencing.
Read about it here: ISP provisioning may prevent Internet connection via broadband (cable or DSL)
The IP address 169.254.9.100 merely indicates a "self-assigned" address which will occur if it's not receiving one from a DHCP server (your modem, in this case). Ignore it since it's a consequence of the above problem.
