I am looking for a simple network monitor for a small site. It just has a comcast cable modem that keeps going down. I Had Comcast out several times and replaced the modem. All I want to do is log the Up\Down status of the modem. I do not need real time alerts. I would like to be able to set it up on a old laptop for a few weeks just to collect information. There are only 3 PCs connected directly to this modem, so I don't need anything complex.
ibewlocal98 which windows? Microsoft Network Monitor 3.4 is the archive versioned tool for network traffic capture and protocol analysis.
Download Microsoft Message Analyzer for updated parser support.
Capture and explore network traffic with Microsoft Message Analyzer 2016 version

You could use the freeware version of PRTG: 100 sensors is plenty for the small site you're looking at.
It will log up/down, amount of bandwidth used, etc. If you need alerting, that's also included, but you don't have to enable alerting if you don't want any. PRTG will save all the data for you, and you can then generate a report after, say, a month, to show how much up/downtime you had.
