Windows 7: 'No Internet Access' IP address shows router not the modem IP address

'No Internet Access' IP address shows router not the modem IP address

Hey everyone.

I've ran into a problem that I can't quite figure out. My internet connection shows 'no internet access' even though my ISP shows the connection is coming into the house just fine. I usually use a router (NetGear-WNR3500U) but I right now I have the Ethernet connection plugged directly into my PC. I tried directly plugging into my laptop and the internet works just fine. So I know the problem resides in the PC.

Some troubleshooting things I have tried.
-Power cycled my modem, router and PC.
-Repinged my connection from my ISP(Comcast Xfinity)
-Used the reset option on the router and the modem
-I was walked through the internet options needed with the tech support from my ISP to make sure DHCP was enabled and every other setting was correct, and he cleared me that all settings were correct.
-Tried ipconfig commands to /renew and /release my IP
When I tried ipconfig /renew I get the error 'An error occurred while renewing interface Local Area Connection : unable to contact your DHCP server'

-Restored my PC to a restore point where the Internet was working

All of these options did not work.

What I think the problem is and I am not sure how to fix it, when I run the ipconfig /all command my Auto configuration IPv4 Address shows 169.254.112.76 which I was told is a router IP address even though I am plugged directly from the modem to my PC with an Ethernet cord. So I think that's my problem? But I am not sure.

I'd be glad to provide any more information needed and I am open to all suggestions. I am pretty tech savvy so any advice I will try.

Thanks everyone.

That would be your ISPs' address, the router would probably be 192.168.0.1 or 192.168.1.1 so, in the properties, advanced button for the ipv4 of your adapter, make sure both settings are on auto, and add the correct router address in the gateway box.

Tried your suggestion, but still no luck. I added that IP address and both boxes are checked...

Can you access the router page in your browser using the 192.168.1.1 or 1.0?

Yes I can, if I plug into my router like I normally do. However I still don't have internet access anywhere when I do that, No wifi through my laptop or any other wireless device.
