I just switched to cable internet from DSL today and I also just received my Time Capsule. I went through the setup process with the Airport Utility and I thought that I had everything working. I can see the hard drive of the Time Capsule, but my internet connection isn't working. If I hook my iMac up to the modem, it works. Now, when I had DSL, I didn't have any kind of router. The technician told me that if I wanted to connect another computer directly into the modem, I would have to call them and give them the ethernet id for my computer in order for it to work. I'm wondering if I need to call the cable company and give them the ethernet id for my Time Capsule. I can list any settings that might be helpful to get a solution, but I don't know if it will make a difference because my Airport Utility says that everything is fine. Any help would be greatly appreciated.
