Cannot Communicate with Primary DNS Server (192.168.0.1)
Hi all,

I am new to the forum and a bit of a novice so please be gentle, its my first time...

I cannot currently connect to the internet on my Dell Inspiron 1200 Laptop running Windows Vista. This happened today after uninstalling Adobe Photoshop Lightroom 4, although I have no idea why a network problem could be caused by a software removal. Do you think it is related?

Both my wifes smart phone and my own work on the same connection from the Sky wireless router that distributes the signal but the Windows network diagram show an excellent local connection to the computer from the router and no connection at all to the internet. When I try to diagnose and fix through the Windows link, the following message is shown:

"Cannot Communicate with Primary DNS Server (192.168.0.1). Network diagnostics pinged remote host but did not recieve a response." Windows has reset the network adapter for the wireless network connection but this does not repair the problem. The problem still exists.

Can you help please? I am currently on night shift with no access to the Laptop but my wife has sent me 3 pictures of the IPCONFIG/ALL information (attached). I will have a go at whatever you guys suggest when I get home in the morning.

Thanks in advance,

Tom

What firewall / security suite or anti-virus do you currently have on the PC - or you have ever had on the PC in the past - any trial ware - like Norton, Mcafee , AVG etc

please would you do the following three tests
------------------------------------------------------------------------
Ping Tests
If you cannot access the internet with this PC, then you will need to paste the results into something like notepad and then copy onto a machine that can access the internet and post the results in a reply here.
Save the file to a USB flash drive or other removable media. Plug it into the working computer with internet access and copy the file and paste here.

Start> Run {search bar in Vista/W7}> type CMD to open a command prompt box
(A new dialogue box - black with white font, will appear on screen ):

Type the following command
Ping 192.168.0.1
Post back the results in a reply here
right click in the command prompt box
select all
enter
control key + C key - to copy
then reply here and
control key + V to paste

Type the following command
Ping google.com
Post back the results in a reply here
right click in the command prompt box
select all
enter
control key + C key - to copy
then reply here and
control key + V to paste

Type the following command
Ping 209.183.226.152
Post back the results in a reply here
right click in the command prompt box
select all
enter
control key + C key - to copy
then reply here and
control key + V to paste
Quote:
For your information only
these tests will check various stages of the connection, the first ping test, ping default gateway checks to see if you still have a connection to the router.
The next two Ping google.com & Ping 209.183.226.152 tests the connection to internet. google is to test by name and the ping test using a number is checking that a connection exists without DNS.
these tests then confirm if there is a dns issue on the connection.

Why is netbios pointed to a different subnet?

etaf,

Thanks for the reply. I usually have McAfee Security Software through my internet provider (Sky).

I thought that this problem was solved yesterday as I accessed www.sky.com on my smartphone to check emails and there was a help section so I opened this to fins that there had been problems caused by a recent software update to the Sky McAfee Security program. It suggested that if customers had lost internet connection, they should uninstall and then re-install the McAfee software. I did this and the problem was solved - my wife was able to access the internet all of yesterday evening.

However, today we have the same problem again, but when I have uninstalled the software, I still have no connection where I did yesterday. This suggests that it is a new problem that now exists without the McAfee sortware on my PC. I can still access the internet through both smartphones and have taken the laptop to another house where the same problem exists (our phones and the homeowners PC works ok).

Below is the CMD information as requested:

Thanks for the help, I'm really getting frustrated with it as my wife has just started an on-line training course and she now can't get on-line. Typical!!

use the removal tool for mcafee

Mcafee Removal Tool
http://service.mcafee.com/FAQDocument.aspx?id=TS101331

http://majorgeeks.com/McAfee_Consume...ool_d5420.html

--------------------------------------------------------------

once removed see how you get on

we have the link to the mcafee issue here
http://forums.techguy.org/networking...s-network.html

also looks like a DNS issue - but have seen mcafee cause this over the last few days

try a couple of things
1) use an open dns
and 2) try safemode
------------------------------------------------------------------------

Google public DNS

Google public DNS
http://code.google.com/speed/public-dns/

Theres also a link on how to setup those DNS IP address up on a PC
http://code.google.com/speed/public-dns/docs/using.html

How to set XP here
http://techie-buzz.com/how-to/google...and-winxp.html

Then once you have set up those DNS entries

Flush & register DNS

Hold the Windows key and press R, then type CMD then press Enter to open a command prompt box (A new dialogue box - black with white font, will appear on screen ):
In the command prompt window that opens, type the following commands:

Ipconfig/flushdns
ipconfig/registerdns


If you receive the message
The requested operation requires elevation.
Then please open the command prompt as administrator
Start> All Programs> Accessories and then right click on Command Prompt, select "Run as Administrator" to open a command prompt.

now type the command again
------------------------------------------------------------------------
- try safemode with networking
as the PC starts keep tapping F8 - a menu appears - choose
safemode with networking - see if that works
