Invalid IP Configuration, other Madness, No Solutions

Out of the blue yesterday my computer stopped connecting to the internet.

I can connect to the internet directly from the modem, I cannot conncect through the router, but I can connect to the router.

I can connect through the router with many other computers/devices in the house.

It happened right before I restarted my computer with a few windows updates... but the internet connection died BEFORE they were installed...

"Troubleshoot" does not solve the problem. Just says wireless IP doesn't have a valid IP configuration.

Disabling/Uninstalling/whatever the wireless card I have doesn't solve the problem.

Virus scan said I'm fine- AVG and Malwarebytes both come back clean.

ipconfig on the bad computer gives me an IPv4 address that will not work.

ipconfig on a computer that connects to the internet gives me a totally different IPv4 address... that does not work on the bad computer either.

Other weirdness- lately whenever I had a few chrome tabs open, the cpu gatdget had my processor at 100%. This is a phenom 1100t x6, pretty fast, and a few internet tabs never taxed it at all before. Speedfan showed the processor running really hot, too, compared to normal. When I shut the tabs, it would go back down. I uninstalled chrome, but still can't get on the internet. (restarted many times now.)

Running w7 64bit.

Can someone tell me what the @#$@# is going on with this thing? And maybe even how it happened?

Here's another fun twist- I connect my router directly (via ethernet cable) to the good computer, or the bad computer, and try to talk to it directly with IT'S ip address.

It asks for a user name and password! Won't accept anything I give it! I went through everything it could have possibly been...

I have also called the phone company and had them check it on their end- they say the connection is good.

I have also bypassed the filter.

Here's something interesting, I did this while googling around...

*****Method 1 – Reset TCP/IP Stack

You can try to reset the TCP/IP stack in Windows to possible repair the Internet connection if it is corrupted. Go to Start, Run and type in CMD. Type the following commands:


netsh int ip reset reset.log


netsh winsock reset catalog

Reboot your computer and see if the Internet connection works. If you have more serious problems with Winsock, read my post from OTT on how to repair Winsock errors in Windows.*****

I also tried unsuccessfully to connect to ANY of my IPs, listed either on the bad computer or the good computer. However, when I restarted... IT WORKED!

Except the connection drops over the simplest things, AND the so-called good computer is now having the exact problem my so-called bad computer is having.

So they switched places, only unlike before the computer that does connect to the internet does so very poorly. I can't even download chrome.

I also got an error message at one point that mentioned an ip conflict.

Is anyone out there that knows what to do???
