Solved: Cannot communicate with primary DNS server

haze_3 · 23-Jun-2009, 11:07 PM #1

Hey,
i have a problem on my laptop when trying to connect to the internet... i have a connection to my wireless network as the signal strength is excellent, i just cant load up the webpages! although having said that this is the diagnostic report that comes up

Cannot communicate with primary DNS server (fe80::19d2:c462:890e:61b7%9).

This is a home wireless connection, im only a beginner

and any help would be much appreciated, also if it could be simplified when explaing so i can understand...

Cheers

Peter

Ive read a few other post with similar problems and noticed that a ipconfig /all maybe of help so here it is

Let's expand those tests.

Try these simple tests.

Hold the Windows key and press R, then type CMD (COMMAND for W98/WME) to open a command prompt:

In the command prompt window that opens, type type the following commands one at a time, followed by the Enter key:

NOTE: For the items below in red surrounded with < >, see comments below for the actual information content, they are value substitutions from the previous IPCONFIG command output! Do NOT type <computer_IP_address> into the command, that won't work.

IPCONFIG /ALL

PING <computer_IP_address>

PING <default_gateway_address>

PING <dns_servers>

PING 206.190.60.37

PING yahoo.com

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

<computer_IP_address> - The IP Address of your computer, obtained from the IPCONFIG command above.

<default_gateway_address> - The IP address of the Default Gateway, obtained from the IPCONFIG command above.

<dns_servers> - The IP address of the first (or only) address for DNS Servers, obtained from the IPCONFIG command above.

If you are on a machine with no network connection, use a floppy, USB disk, or a CD-RW disk to transfer a text file with the information to allow pasting it here.

Thanks for the help so far...
ive conducted the other commands you requested, i wasnt quite sure with the DNS ping but i tried a few different things...

Well, that wasn't it exactly, but close enough to see what's going on.

Is that router a modem/router, or do you have a separate modem? If you have a separate modem, please connect a wired connection directly to the modem and repeat the ping tests. The following data comes from the IPv4 results, not the IPv6 stuff, which is not used. The correct address format for these data fields will be four plain numbers separated by periods, i.e. nnn.nnn.nnn.nnn. The fields with the alpha mixed in are the IPv6 stuff and not useful.

<computer_IP_address> - The IP Address of your computer, obtained from the IPCONFIG command above.

<default_gateway_address> - The IP address of the Default Gateway, obtained from the IPCONFIG command above.

<dns_servers> - The IP address of the first (or only) address for DNS Servers, obtained from the IPCONFIG command above.

**TerryNet** · 25-Jun-2009, 11:01 AM #6

Well, John, it's time to add yet another red or purple explanation--something like "IP address means IPv4 address if there are both IPv4 and IPv6 addresses."

Note that the diagnostic info quoted in initial post is "Cannot communicate with primary DNS server (fe80::19d2:c462:890e:61b7%9)." Does this imply that Vista is trying to use the IPv6 for DNS, or just that it tried pinging all the DNS servers?

You probably noted these differences between the initial and subsequent ipconfig /all; but just in case you didn't and they include a clue ...

1st: DNS Suffix Search List. . . . . . : mshome.net
2nd: DNS Suffix Search List. . . . . . : Belkin [default for Belkin router]

1st: DNS Servers . . . . . . . . . . . : fe80::19d2:c462:890e:61b7%9 [unusual?]

2nd: DNS Servers . . . . . . . . . . . : 192.168.2.1

1st: NetBIOS over Tcpip. . . . . . . . : Enabled
Connection-specific DNS Suffix Search List : [never saw this here before]
mshome.net
2nd: NetBIOS over Tcpip. . . . . . . . : Enabled

JohnWill · 25-Jun-2009, 03:29 PM #7

Yep, that's probably my next change.

You're right, I didn't spot the change from Belkin to mshome, wonder what that's about. Seems that probably has something to do with this as well, but I'm not sure what.

The hex for the DNS server is IPv6, though again it appears in a strange place.

JohnWill · 25-Jun-2009, 03:30 PM #8

Time for a stack reset here, just to cover all the bases.

TCP/IP stack repair options for use with Windows Vista.

Start, All Programs\Accessories and right click on Command Prompt, select "Run as Administrator" to open a command prompt.

In the command prompt window that opens, type type the following commands:

Reset WINSOCK entries to installation defaults: netsh winsock reset catalog

Reset IPv4 TCP/IP stack to installation defaults. netsh int ipv4 reset reset.log

Reset IPv6 TCP/IP stack to installation defaults. netsh int ipv6 reset reset.log

Reboot the machine.

smartscorpion · 26-Jun-2009, 03:20 PM #9

even i am facing the same problem...
and i have tried stack reset as well after reading ur answers but even that didn't help...

what next to do?

**TerryNet** · 26-Jun-2009, 04:06 PM **#10**

For smartscorpion's issue please continue here.

haze_3 · 01-Jul-2009, 10:00 PM **#11**

thanks for the help thus far...

i conducted the stack reset and still cannot get a connection... what do i need to do next?

i have some more information that maybe helpful
my wireless router is a 'belkin - wireless G 2.4Ghz 802.11g' model F5D7230-4
my modem is a 'Siemens Speedstream 4200 - ethernet/adsl modem'

i dont know if that helps.

i must apologise for the late replies have been busy with university exams

Cheers

Make sure that you have the Speedstream 4200 modem/router connected to the Belkin's Modem port.

Access the Belkin and make sure it got a good WAN (Internet) IP configuration from the Speedstream. If you are not sure what's good, just tell us the IP address, mask, default gateway and DNS server(s).

haze_3 · 06-Jul-2009, 12:31 AM **#14**

ok when i went to connect it all up, my internet dropped out of my PC and i couldnt connect to the internet...

Should i reset the router, and maybe try reinstalling the whole lot? im at a loss to where to go...

**TerryNet** · 06-Jul-2009, 10:44 AM **#15**

See post # 13.

Also, if you can access the internet by connecting directly to the Speedstream modem/router you could show us the ipconfig /all for that connection.
