I have Comcast cable and I am using a linksys cisco e1000 router.

Everything worked until a couple days ago. I can connect to the wireless network with both my Mac and my Windows 7. However, there is no internet connection on the Windows. If i try to go to google, i get an error saying the dns lookup failed.

The internet works on my mac and my ipad. I recently starting getting DNS errors with my PS3 as well. Is there an ipconfig I can pull up from my mac?

I have restarted my modem and router a few times with the same results.

If you need more information, let me know.

thanks

and welcome to the Forum

Sre you trying to connect wired or wireless?

Lets take a peek at your network environment:

On the Windows 7 pc, First:

Power Cycle everything . . Turn off the Modem, router and all pc's . . turn on the Modem and wait a few minutes for the lights to stabilize . . then turn on the router, then one pc at a time. See if you connect to the internet.

Then: check your browser's settings, remove any proxy settings if foundhere's how.

Then:

with the pc connected to the router, Click on Start . . Run . . type CMD

At the > prompt type type the following command: IPCONFIG /ALL


Note that there is a space before the /ALL, but there is NOT a space after the / in the following command.

Right click in the command window and choose Select All, then hit Enter. Come back here and Paste the results in a message.

If you are on a machine with no network connection, use a floppy, USB drive, or a CD-R disk to transfer a text file with the information to allow pasting it here.

Your router is misconfigured to only give ipv6 dns entries

DNS Servers . . . . . . . . . . . : fec0:0:0:ffff::1%1
fec0:0:0:ffff::2%1
fec0:0:0:ffff::3%1

I would suggest you need a ipv4 dns server ip. Google's 8.8.8.8 is a good one for you to use.

You will need to make this change in the routers dhcp server settings
