I bought a Linksys E3000 Router. I have hooked it up and connected my PS3, laptop, iPad, 2 guest laptops on occasion with no issues. However, my fiancee's laptop will not connect to the internet. It connects to the network fine, just not to the Internet. I keep getting the same error "Cannot communicate with Primary DNS Server". I searched through this forum and found a few threads, but none of them solved my issues, so I am asking for help. She is running Windows Vista SP 2. I tried all three of the solutions suggested by Vista, but they all failed. I also did a hard reset of the laptop, router, and modem. Waited a little while with everything unplugged. Still cannot connect to the interent and get the same error message.

did the resets all work ok with no errors ?

whats the make and exact model of the PC
windows version

see if we can find an updated adapter

also lets see an xirrus screen shot

------------------------------------------------------------------------
{run Xirrus Wi-Fi Inspector} Download and install
If you cannot access the internet with this PC, then you will need to copy the program across to the faulty PC

http://www.xirrus.com/library/wifitools.php
Direct link to the program is here http://www.xirrus.com/library/wifi_download_redirect.php
Then run and install the program
if you get an error - You need NET Framework installed for the WiFi Inspector to function.

Run the program

post a screen shot of the program running - if there are a lot of networks showing can you click on "networks" top lefthand area - so we can see all the network information, and also post which network "Adapter Name" (1st column) is yours on the list

To post a screen shot of the active window, hold the Alt key and press the PrtScn key. Open the Windows PAINT application and Paste the screen shot. You can then use PAINT to trim to suit, and save it as a JPG format file.

all resets worked with no errors. Just told me to reboot. the flushdns just opened up a lot more commands, and didn't really ask me for anything. The other 3 all said it was OK and told me to reboot

That model was on a label (I saved all the stuff from the purchase). The command prompt came out with the same thing as right clicking on Computer --> Properties. dv6700 Notebook PC

I downloaded the new driver and ran it and rebooted the computer and it still isn't working. No issues connected to the Network, just no Internet

Yes thats the issue we have seen

try right clicking on the adapter in device manager and deleting / uninstalling and then reboot and let windows detect the adapter and install the drivers again
ALSO
remove the wireless security on the router and see if that works OK - sometimes taking it off and then resetting may help
you should also removed the wireless profiles

------------------------------------------------------------------------
Wireless Profiles
http://mgmcc.forumotion.net/networking-tutorials-f17/removing-an-existing-wireless-profile-t109.htm
- Vista/Windows7:
http://www.tp-link.com/support/showfaq.asp?id=214
- delete the wireless profiles
Start> control Panel> classic view> network and sharing center> manage wireless networks

Delete the profiles
you will then have to enter the wireless security key for any networks you connect to

Wireless Profiles
http://mgmcc.forumotion.net/networking-tutorials-f17/removing-an-existing-wireless-profile-t109.htm
- XP
http://www.tp-link.com/support/showfaq.asp?id=186
- delete the preferred networks
start> control panel> network connections> right click on the wireless connection> listed wireless networks tab in the preferred network list click on each one and - remove button

you will then have to enter the wireless security key for any networks you connect to
