Time Capsule constantly losing connection with Motorola SurfBoard cable modem on BrightHouse/TWC

Solution the past few months has been to leave Diagnostics open and start over a dozen times a night.

I can leave Airport Utility open and watch the "Internet" globe turn from green to orange maybe once every two minutes and then reset itself.

I have restarted every device numerous times.

Thoughts?

If you connect the cable modem directly to one of your Macs, does the signal still drop? Does the cable modem config page offer any clues in the logs?

In the log, once an hour there is a DHCP reset.

The other numbers seem about like what I can find online as normal.

silverarios question is a good one: What happens if you connect your Mac directly to the modem?

You need to find out if the problem is the TC or not.
