Q: Can't communicate with Primary DNS Server

I recently bought a new laptop with windows 7. I was able to connect to the wireless internet at my house without problem....until a few days ago.


Network Diagnostics throws up the following error message: "Windows can't communicate with the device or resource (Primary DNS Server)."

I have a full strength signal and I appear to be connected but there is "no internet access".


I am able to connect on the wireless at my parents house no problem.


this is really frustrating as the internet was working just a few days ago and I haven't installed/unstalled anything. I am able to connect on myold laptop without problem!!


Thanks in advance, Sally

Hi sallyh75,


That seems to be a strange behavior. Let us try the following methods and check.

Method 1. Let us reset the TCP/IP and verify.
To reset the TCP/IP stack go to this article and follow the instructions.

Method 2.
Step 1.

1. Connect to your router (by typing 192.168.0.1 or 192.168.1.1 in the address bar) and log in. Check your user manual or documentation if you do not know the log-in credentials.
2. Make sure you are in the Setup -> Basic Setup category.
3. Scroll down until you see 'DHCP Server' - if it is disabled, select 'Enable'.
4. Enable DHCP If you want, you can change the number that the DHCP IP assigning starts. (this is optional)
5. Use the DNS servers provided to you by your ISP. There are many DNS servers out there. It's best to use your ISP's if possible.
6. Scroll down and click 'Save Settings'.

Step 2.
1. Click on Start and then Control Panel.
2. Go to Networking and sharing center and then click on Change adapter settings.
3. Right click on Local Area Connection and choose properties.
4. Highlight Internet Protocol Version 6 and click on Properties.
5. Choose Obtain DNS server address automatically and press Ok.
6. Choose Obtain IP address automatically.
7. Repeat the steps for Internet Protocol version 4 as well.


Hope this helps.
