Windows 7: DNS server is not obtained automatically

DNS server is not obtained automatically

I use my 2nd computer for internet using wireless adapter via 1st computer's router.

However, when I diagnose my 2nd computer network connection i get an error "Your computer appears to be correctly configured, but the device or resource (DNS server) is not responding"

this error was found when I replaced old road runner internet service provider's cable modem to new one

Internet works though, it disconnects randomly and very unstable.

I did some alternation other forums suggested like cycling the router, ipconfig /flushdns, calling road runner and ask them for dns address but non of them fixed the issue

I also manually assigned google dns address (this seemed it fixed the problem but internet was slower than the time with no error before)

How can I fix this problem ? help will be appreciated thanks.

With your computer setup as normal, click on Start then Run or press Window key (next to left Ctrl key) +R and paste the following into the Run box, exactly as shown, including double quotes:

cmd /c "ipconfig /all > postme.txt & ping yahoo.com >> postme.txt & notepad postme.txt & del postme.txt"

and press ENTER.

A file will open in Notepad. Please copy and paste the contents here. Close the Notepad window and the file will be deleted and the Command Prompt window will also close.

If you don't have a Run selection off the Start menu, see here: Enable Run Command on Windows 7 or Vista Start Menu

When you switched to new modem does your IPS know it? If not, a possibility is that your Modem isn't accepting more than one IP address from your network to access your ISP. Notice the Connection-specific DNS Suffix is empty.

"Your computer appears to be correctly configured, but the device or resource (DNS server) is not responding"

It just means that the DNS Server isnt responding to pings.

Check your DHCP settings on your router. The DNS IP Address supplied by your router should be 192.168.0.1 which its not at the moment as its giving you an external DNS Server of your ISP.

If you can post again a screen shot of your ipconfig/all with the windows expanded all the way "sample below" it would be most helpful.
