Windows 7 Desktop With Wired Network - Connected To Network But Not To Internet

[IAmOfTheWise]

I have a brand new, custom-built Windows 7 desktop. I make use of a modem plugged into a coaxial cable to access the Internet. No wireless router, no wired router. Just a modem and a 25 foot long cable.

This past weekend, my Internet connection went down in the middle of the night. My cable company and my IP are the same, but my cable service was uninterrupted. I tried resetting my computer, the modem and doing a total power down and unplug/replug to no avail.

I still kept getting the same message about how I was connected to the network but couldn't access The Internet. The really vexing part was that the Network diagnostic said that my system seemed to be configured correctly but that the DNS Server was not responding.

I called my IP. Went through the steps again with the automatic system. Nothing.

I asked to speak to an agent. They walked me through the same steps. Again, nothing.

They checked everything on their end and we ran ping tests and flushed the DNS. Nada.

They said something was clearly up and it was probably on their end, but he couldn't do anything until an agent looked at the system in person. They were able to send a cable guy out within the hour. After an hour of trying all the same things I'd already done three times, he called in to his supervisor, the supervisor suggested switching the modems out.... and for some reason that did it!

Things were fine until three days later. Tuesday evening, I returned from home to find my Internet was out. Again. Exact same issue. I was connected to the network but could not connect to the Internet.

My call to my IP this time was less than helpful. Even though they had a record of the service call on Saturday and this being the exact same problem, the tech couldn't offer any suggestion other than my computer was messed up somehow. I challenged him to explain why, if that were the case, that changing the hardware did something to temporarily fix it. He didn't have an answer, of course.

ADDITIONAL ONE: I found one article I found on-line with my smart phone that seemed to resemble my problem: http://www.sevenforums.com/network-sharing/115722-network-2-really-means-no-network.html

The picture here resembles what my Networking and Sharing Center looks like, right down to the Network being named Network 2. I swear that wasn't its name before and I currently have two Network listings.... Network and Network 2. The problem is that my system keeps trying to select Network 2 and I have no way of seeing the listings unless I am connected to Network 2... in which case I can't delete it.


ADDITIONAL TWO: Here is the information from my IPConfig

if it is just the dns not responding, use the free google dns.

this is on the public network change it to domestic one that should let you acces the net .

this is on the public network change it to domestic one that should let you acces the net .

How would I go about doing that? Despite being fairly tech savvy, I don't have a lot of experience with networks. I'm not sure how the heck it got changed to a public network instead of a private one.
