I was pretty sure I ran it as admin, however I re-ran flush.bat as admin and here is my new ipconfig.
EDIT: I am still having the same issues though.

Can you get in to your router's configuration pages? Type 192.168.2.1 into the address bar of your web browser and press enter. Find out what DNS addresses are assigned and post them here (your PC is not getting valid addresses from the router).

Also go to Control Panel -> All Control Panel Items -> Network and Sharing Center and click on "Change Adapter Settings". Right click on "Local Area Connection" and select properties. Left click "Internet Protocol Version 4 (TCP/IPv4)" and click properties. Are the two radio buttons "Obtain ... automatically" selected? If the radio button for DNS is not set to auto, what addresses appear there?

Cancel or "X" out of that dialog and do the same for the "Internet Protocol Version 6 (TCP/IPv6)" item. Then cancel or "X" out of all the popup dialog boxes.

I'm also wondering about the info in the section about "tunnel adapter isatap:Belkin". Do you know if you're doing any IPv6 over IPv4 using secured connections? I wonder how it's DNS value got set....

DNS Address: 65-32-5-111
Secondary DNS Address: 65-32-5-112
I followed your instructions to get into my IPv4 properties and it obtains IP address automatically, as well as DNS server address automatically.
Am not sure how to "do" something over IPv6 rather than IPv4.

So those are the DNS addresses in your router? You have internet service with Road Runner?

If so, and those dialog boxes I asked you about were set to auto, that tells me that the flush.bat file didn't take.

To run that flush.bat file successfully, you right click the flush.bat icon on the desktop, then left click on "Run as Administrator".

Is that what you did? If not, try it again, the way I just described...

I do have Road Runner.
I ran flush.bat as admin twice. I will open CMD this time as admin, and then type in the values of flush.bat.
Edit: here is my new ipconfig/all since typing in the values from flush.bat manually.

I've looked in several other posts, and nothing has quite worked out for me thus far. I have general medium level of understanding relating to computers. Hope to hear an answer soon.

Thanks in advanced.

If you haven't done so already you should reset your router, should be a button on the side of the router for this or you can unplug it for about ten minutes.

After that you can access the routers set up page by typing 192.168.2.1 into the URL of your browser. Password might be admin.

I would also try using a different DNS server, you can try typing these DNS servers into your routers set up page as a test 8.8.8.8 and 8.8.4.4

If you haven't updated the driver for network adaptor now would be a good time to do that.

Good ideas by chev65. I would also suggest shutting down everything together: modem, router, and all connected (wired and wireless) devices. Wait a minute or so, then start the modem. Wait for it fully come online and then start the router. When the router fully comes on line then go ahead and start the other connected devices.

Thanks everyone for your help. I will definitely attempt to shut everything down for 10 minutes, and then start booting up.
I did have a concern which I just stumbled upon. I was having severe issues with network connection again "Local Are Connection" doesn't have a valid ip. I then turned on my laptop and noticed that I was able to connect to the internet, but still was having issues on my PC.
Any thoughts on this?

I'm so sorry to have missed your previous post.

I would go ahead and do the full shutdown and sequential startup.

If that doesn't work, go to Control Panel -> All Control Panel Items -> Network and Sharing Center and click on "Change Adapter Settings". Right click on "Local Area Connection" and select properties. Post a screen shot of the dialog box you get.

a fix

The only thing that has worked for me was to contact the manifacturer.

My laptop had gone into hibernation over the weekend and I was having the same porblem on Monday morning.
Any HP support had me take out the battery and unplug the mains power. Hold down the power button for 20 secs and low and behold it worked.
I had to reboot the modem/router for one last time.

Turns out that hibernation stores files on the HD and this screwed with the IP address.

Hope it helps someone else
