Hi, I don't quite understand what is the signal levels so I pasted the cable modem pages. Please let me know if you need more info. I am still experiencing brief interruption every so often. Thanks.

Your signal levels look good, but it's possible they are changing throghout the day. Were these signal levels grabbed during the issue in question or shortly after?

Yes.
I talked with customer support and they said my modem is ok. Ping test shows no problem. They said that my internal network would be a problem. So I connected PC directly to the modem to test the interruption. As a result, I am still having the problem even from the PC directly connected to the modem.
Any idea?

Call them and make a stink to get the modem replaced. I'd bet the power "wall wart" has gone bad and is not supplying clean voltage or is supplying low voltage at the device's current. If your feeling charitable you might find a "wall wart" with appropriate voltage rating and plug polarity and change it yourself.

This was not a modem problem. I called them to cancel static IP address, then Comcast did something on my modem from remote, then the probem seems fixed. Since then, there was no interruption occur. I don't know what did they do to the modem, but it works fine since then. By the way, today they reset my modem and my IP address is no longer static. The problem was that they did not noitfy me before they reset so I had to figure out what was happend and re-configure the modem since they wiped my port forwarding settings. Good job Comcast 😞
