Thread Starter
Dec 1, 2020
Hello, I found the Primary DNS Problem from some days back. Firstly I thought this is an Internet Connectivity issue. but I will try to browse something on a different PC, the Internet works fine, I am very frustrated about this, I searched many of the videos on Youtube. and also do reset my Router as well, but the problem is the same as previous. I am not able to understand what is the issue. Please help me to out this, waiting for Your Suggestion?

waiting for Your Suggestion?
EDIT (12/15/2020): I don't know why much of the following had a strike thru. Just now fixed it.

My suggestion is for you to describe your problem. "same as previous" doesn't give us anything to go on.

If this is a networking issue please also ...

Open a (black) Command Prompt window:
Hold the Windows logo key and press r; in the Run box type cmd and click on OK.
(In Windows 10 you may have to use some other procedure to get a Command Prompt window.)

Type the following command:


[Note that there is no space between the slash and ALL.]

[Press ENTER after ths command.]

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

If necessary use a text file and removable media to copy the results to a computer with internet access.

Hi @davidbon

1: Open the RUN utility.
2: Type IPCONFIG/ALL command
3: This will show the IP Address
to reset your Connection Setting you can type the below command.
