Network Trouble.

I honestly have no clue what is happening at this point.

At best I can describe is that my Internet gets interrupted by some unknown cause and just stops working all together. The only way it fixes is when I restart the modem itself and it works perfectly fine. This seems to happen within a fixed time as if on a timer. I've tested my modem and ethernet cord on another computer and it works fine on another computer without any trouble.

This problem will come and go randomly as if computer has moods. I've reinstalled the drivers from the company website without any change.

My network is run by:
NVIDIA nForce Networking Controller
Ver 50.0.9.0.

From your description, I am assuming you are not using a router (i.e. directly connected to the modem). If this is not true, let me know.

I can only think of two scenarios that would cause this to happen at all. The first, and not very likely, is that your modem is programmed to disallow traffic after some event has been hit (i.e. malicious traffic). The second, is that your modem is shutting down/freezing because of packet flooding.

Packet flooding can be caused by a lot of things but most of the time it is caused by malware. Bots and SMTP mailers are usually what does it. I recommend you post your question in the Cyber Security forum and see if they find any infections. Of course we would be happy to help if you think there are other symptoms that we should look at.

Thanks for reasponding. I currently running no router to my computer.

I've ruled out the modem as being the problem when I ran a test with the same modem/cables on another machine without running into the same problem at all. It just ran problem free (It was a Mac Laptop OS X) without any of these problems.

I will try the security forum and see if that is the problem. Thank you once again for your assistance.
