[SOLVED] Monitor and Log Internet Disconnects

Post by Catsbark »

In our household, we have several computers (some Windows and one Linux), three smartphones, and a couple of TVs connected to the Internet through our router and cable modem. Recently, we have been experiencing multiple Internet disconnects - usually about two minutes long, and self-reconnecting. I have set up one laptop running Windows + Chrome + Internet Connection Monitor Extension. It correctly noticed a disconnect yesterday evening, but that extension doesn't really keep a good log of time, date, and duration of disconnects. It also doesn't tell me whether the disconnect happened somewhere in my LAN, or if it happened somewhere outside my control.

I hope this forum can guide me to an application (preferably for my Linux box, but something on Windows would be acceptable) that can monitor the connection through my router and cable modem and out into the wide world, identify disconnects and log them, and determine if the disconnect is internal or external. Is this too much to hope for?

Thanks in advance for any help. It probably isn't relevant, since the disconnects occur with all of our connected devices, but here's my system info:

Re: Monitor and Log Internet Disconnects

Post by Catsbark »

I think I've got the monitoring figured out: I set up an old laptop with LM 20.3 running Google Chrome browser and the Internet Connection Monitor extension. This monitors and logs disconnects from the Internet. The same machine has two Terminal windows open, each running Ping with a 10 second interval - one to my router, one to my cable modem - and logging the results with timestamps to respective text files. Now if I get a disconnect in the browser, I can check the text files to see if there's a corresponding error at the modem or router.

All this seems to be working as expected, but it's an old laptop and the battery is dead, so when the power went off during the night, so did my monitoring. The solution to that would be to buy a new battery, but the display is deteriorating too, and I don't think it would be worth the investment. I have another old laptop, also with a dead battery, with a good display but dead keys in the keyboard. also not worth a new battery. I guess the point of this post is mostly to gripe, but if anyone has comments about my monitoring system, I'd like to hear them.

I'll leave this topic open for another day or two to see if anyone comments, then I guess I'll mark it solved.

I had hoped someone would have something to say on this topic, but alas, I guess it is not to be.
Marking it solved.
