DNS lookup failed (Moved from Windows 8 forum)

go control panel
network and sharing centre
on left pane click change adapter settings
in the white window right click the qualcom Atheros adapter
click properties
in the small white window scroll to IPv4
click the properties button
in the window that opens check that IP address is checked obtain automatically and the same for dns server
if they are not so checked - do so and then exit out by OK and close

reboot and see if that works OK

The problem is caused by the wireless adapter attempting to use the IPv6 addresses for the DNS

I HAVE HIGHLIGHTED in red the cause of the problem


If the above recommend does not solve it - go back to the steps described and on the small white window - scrolling to IPv6 - uncheck that box, then click OK
Still checking that IPv4 - IP and DNS are set automatically - after reboot from unchecking IPv6

IF THAT works it is NOT the solution it is only a test
we will proceed when you post the results

Also go back to control panel network and sharing centre change adapter settings
select the wireless adapter
On the menu bar click view status of this connection
on the window that opens click the details button please and post a screenshot of that
Also click the wireless properties button and check that you are connected to the network ISP that you should be


The latter step may of course be achieved by holding the mouse on the wireless connection icon in the notifications area or by clicking on it you will see all wireless networks


For your info - Google, facebook and you tube and others started to use IPv6 about 12 months ago or so, but most sites still do not use it, they use IPv4 and that is the nature of your problem


When you return with the info I have requested we MAY be able to make progress

If you need any additional info i will react asap.

I'm just trying to learn on the job w.r.t. IPv6. Can't think of anything else until you can answer at least some of my post # 6. How about for the other PC:

Open a (black) Command Prompt window:
Hold the Windows logo key and press r; in the Run box type cmd and click on OK.

Type the following command:

IPCONFIG /ALL

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

[Press ENTER after each 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.

Ok, here the screenshot of the details of the wireless adapter. Im not sure what you mean by the second partacboatmaster. I can see all available networka in my area and it shows to have full connection to the network hitron-3cc0.

@terry. I posted my configall in my first post. Im on my phone so im a bit slower but thanks again.

I apologies, the tool I posted does not support 8.1 as Mac has pointed out.

However there is another way of doing it which involves modifying the Registry.

I would wait to see if Mac or Terry have anymore suggestions prior to trying this.

Press Windows key + R, type: regedit press enter.
Once open insure that Computer is highlighted at the top of the list (left pane), once highlighted click on File then select Export. Save the file to your desktop and name it 20140710. (This is just a backup copy)

When doing the next steps, if at any point something does not match up as posted STOP and respond back here.

Next within regedit navigate to the following;
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Tcpip6\Parameters
In the right pane, right click over a blank space and select New → DWORD value.
Name the newly created DWORD DisableComponents. Then double click on the new DWORD (disablecomponents) to modify.

In Value data field type: 0x20
Base should be marked on Hexadecimal.
Press Ok

Click on File and Exit. If asked to save changes select Yes. Reboot the machine.
