I think this is the right forum for this question:

I need a program or utility that can keep a lit (log?) of when 
Internet connection is connected and disconnected.  It would need to 
work through my router to "look" at the cable modem at some small 
interval to detect if the cable modem is connected to the cable broadband.

I am using Windows XP SP3 connected to a wireless router which is 
connected to the cable modem.  The network doesn't drop connection to 
my PC's but they can't get to the Internet through the broadband connection.

The reason I would like this monitoring program is that during a 
period of period of about 3 hours around noon, I cannot get to the 
Internet from any PC and can see that the cable modem is not 
connected by it's indicator lights.  It comes and goes, maybe in 3 to 
15 minute intervals.  I'm not able to get the cable provider by phone 
when it is disconnected so that they can look for a problem.  Of 
course every time they come out to look at the lines all is OK and 
can't find any problems.  I thought if I could show the down times 
they could help locate what the problem is.

Any programs any one knows about to do this?
