For one week now I have been successfully connected to the Internet using my Time Capsule + my Xfinity supplied modem/router. When it was hooked up, I told the service guy that I didn't want to use the router function on the supplied modem; that I wanted to use my Time Capsule instead. He told me that I could do this if I put the xfinity router in Bridge mode. Done and done. After one week of flawless service, all of a sudden I lost Internet. The Airport utility suggested that my internet connection was lost and my time capsule was fine. I called xfinity, multiple times, and after many setting changes and restoring the Time Capsule to factory settings it looks like the only way I can get Internet through my time capsule is to leave bridge mode "off" on the xfinity supplied modem/router. Now I'm stuck with a "Double NAT" error that I'm forced to ignore until I can find a better solution. Thoughts?
