Intermittent internet disconnection in the past one or two weeks

I have been experiencing intermittent internet disconnection for the past one or two weeks. The disconnection lasts usually for a few minutes. The internet connection is restored automatically. Very annoying.

My location is in the North Shore (NE of Boston). Has anyone else in this area experienced this problem?

Could you paste your router's System Logs around the time when the Internet goes out? Please redact all IP addresses and hardware addresses that may lead to the identification of your equipment, which is not very secure in this public forum.

The log should help us decide whether the problem is with the router itself, or the fiber line is loose, or some other things are wrong.

Thank you. I have not experienced the problem in the past two days or so. I will take a note of the time and check the log next time.

BTW, do you know how to block an external address? When I checked the log, I found an Amcrest IP camera keeping having failures like the following:

Dec 31 23:13:31 2023 local1.err<139> named[2082]: client @0x2362218 192.168.1.230#60900 (dh.amcrestsecurity.com): view internal-clients: query failed (SERVFAIL) for dh.amcrestsecurity.com/IN/A at query.c:7118

There are lots of entries like this.

This Amcrest IP camera is on your network correct? I.e. It is a camera that you installed?

This error just indicates the camera is trying to find the IP address of the user-friendly name dh.amcrestsecurity.com, but the router could not find it.

These cameras typically call their home base periodically for some cloud features or sending some data or stats unknown to the end users. You could block its Internet access entirely, but would prevent you from remote viewing as well.

Thank you. I have blocked the camera.

I will report back once the issue occurs again.
