I started trying your program because of prgrams droping the connection over the internet ISP says they can't see any problem.

at a few points during the day we get 100% packet loss I am attaching a file for you to look at just wanted to see what you think.

Thanks

I did confim with ISP that the first entry is our cable modem.

The failure point is between your computer and hop 1 someplace (possibly at hop 1).

There are a number of possible reasons for this:

* Bad network cable someplace
* Bad power cable on your router or your cable modem
* If you have a hub or router, there could be a problem with it
* Bad network card inside your computer
* Depending on where exactly the data is going to report at hop 1 (it could be that hop 1 is actually physically at your location, or it could be inside the cable complex), it could be a bad coax cable.

There are a few things you can do to test.

* If you have a router or hub, try connecting your computer directly to the cable modem.
* Switch your network cable for another
* If you have another computer, try from more than one computer at the same time and see if they both report problems. If so, then you can pretty safely eliminate the part of the network path that is different between the two computers (ie: cables, network cards, operating system).
* Try disconnecting the Coax cable from the back of your cable modem. If you get packet loss at hop 2, but not hop 1 (ie: hop 1 still works fine), then the problem is with the cable modem, or something between the cable modem and your computer. If packet loss starts at hop 1, then try the other steps above and then contact your cable company.

The ideal situation is to know how often these outages normally occur. If they happen every 10 minutes, then you can have a cable company representative come to your location and you can demonstrate the problem. If they only happen once every 4 hours, and then only at night, you're going to have a more difficult time.

Good luck!
