How do I fix DNS error cannot connect to DNS server?

Hi, I am having a problem getting onto the internet. It keeps giving me the cannot find DNS server or cannot connect to DNS server error. It has been working perfectly for the past 6 months and today I upgraded from ATT DSL to ATT high speed DSL. The net works fine if I hard wire the modem to the pc, but as soon as I put the router in it gives me the error. I have tried resetting the DNS and clearing the cashe from CMD, resetting the router and modem, power cycling them both, factory resets on both, spent hours on the phone with ATT not sure what else I can do to reslove the issue. I have a HP pavillion desktop with Windows 7, a Motorolla 2210-02-1002 modem, and a Netgear WGR614v10 router.

This is the IPconfig I get when the router is hooked up with the modem (Net does not work)

Hi EricTorres,

·         Did you make any changes on the computer prior to the issue?

Follow these methods.

Method 1: Follow the steps:

Step 1: Boot the computer in safe mode with networking and check if the issue persists.

Advanced startup options (including safe mode)

http://windows.microsoft.com/en-US/windows7/Advanced-startup-options-including-safe-mode

Step 2: If the issue does not persist in safe mode, perform a Clean Boot  to see if there is any software conflict as clean boot helps in eliminating software conflicts.

Note: After performing the troubleshooting steps in clean boot, follow Step 7 from the link to return the computer to Normal startup mode.

Method 2: Disable the security software temporarily.

Note: Antivirus software can help protect your computer against viruses and other security threats. In most cases, you should not disable your antivirus software. If you do have to temporarily disable it to install other software, you should re-enable it as soon as you're done. If you are connected to the Internet or a network during the time your antivirus software is disabled, your computer is vulnerable to attacks.

Method 3: Follow the steps from the article.
