Dell Studio 1558 laptop - The DNS server isn't responding

Hello Experts,

I have a problem i'm trying to resolve. I have a Dell Studio 1558 laptop that has never had a problem accessing the internet wirelessly or hard wired. Well this changed the other day. Now my laptop is unable to access the internet wirelessly or hard wired. The network adapters show "no internet connection" as the status. I do have another laptop that my wife uses and a workstation that I use as well and both of those computers can get to the internet fine via our home network. Things I've tried to troubleshoot for the problem laptop (Dell Studio 1558) are:

1. I can get ipconfig /all information where it shows the machine has a IP via DHCP and DNS servers are listed.

2. I performed the Windows 7 diagnostic function and it came back with a result of "The DNS server isn't responding"

3. I have researched this on the internet and found folks that had similar symptoms with other types of laptops so I tried the suggestions but still have no luck resolving the issue.

Hopefully expert-exchange can help me resolve this issue so I can get this laptop back online at home.

    Try changing your Primary DNS server to and your secondary to (Both Google DNS servers).  See if that helps.

    I've had a couple of computers with similar symptoms come in in the past couple of days after a windows update. Try doing a system restore to before your last windows update, that worked for us both times.

    also, you may try changing your DNS settings ion your router to freeDNS or google's DNS servers like another user mentioned above (he said to set them on your pc).

    Try pinging an IP for the Google DNS servers.  Try pinging an outside IP address, not by name.  If packets are going out just fine then change your DNS server to the ones xDUCKx suggested.  If the packets are not going out, then the problem isn't the DNS and you should probably consider performing the system restore as sysreq2000 suggested.

    Check your internet settings... go to the control panel,  click on internet options icon, click on the connections tab, click on lan settings box, then make sure automatically detect settings box is checked, and make sure the use a proxy server box is unchecked, click the two okay buttons. some times malware can cause you to lose your internet connections. I would do a malware scan, unfortunately if you cant connect to the internet this is more difficult you can download malwarebytes and roguekiller on another computer save it to a memory stick and then install the software on the problem laptop.
