I just got a 1TB Time Capsule. I wanted to use it for backup and to replace my aging Linksys router. I set it up and got a green light on the TC and my iMac was communication with it. However, I couldn't get online. I spent 40 minutes on the phone with Applecare where I reset everything numerous times. The service person ended the call by saying that the issue is with my ISP and that I need to call them. How can that be if I was online and working fine with the old Linksys just before that? She said it had something to do with the cable modem not communicating with TC. I'm very frustrated as usually Apple products are very user friendly and ready to go out of the box. Thanks for any help.
