DNS Server not found

[Reece212]

Hi everyone,
I'm having troubles connecting to the internet wirelessly and using a Ethernet cable, when I troubleshoot I get "DNS Server not responding".
I'm not very good with computers, but just incase here is my ipconfig /all;

Hi there, download this text file, save it to desktop as flush.bat
Right click on the file and select Run as administrator.

Hi Reece212, and Dinesh

Not to hijack your thread Reece, but I'm having the same problem, and I would like to ask Dinesh....

What is the purpose of the File flush.bat ?

Hi Reece212, and Dinesh

Not to hijack your thread Reece, but I'm having the same problem, and I would like to ask Dinesh....

What is the purpose of the File flush.bat ?

It resets the hosts file, releases and renews ip address, performs flushdns, resets winsock catalogs and restarts your pc.

You might also like to change the DNS servers on your router (please see the router's instructions for details on how to do this). I use the OpenDNS servers as detailed below.

Primary DNS Server: 208.67.222.220
Secondary DNS Server: 208.67.220.222

 

[Reece212]

I tried running flush.bat, it opened up a cmd window for a few seconds, restarted, still have the problem.

I tried changing the 2 DNS addresses, still the same problem.

 

[Dinesh]

Call your ISP.

 

[metalmania31]

Either it's your router's configuration or your ISP is down for some reason. The DNS is pointing it looks like to your router which obviously won't work. But it should be automatic so something is configured wrong.

Thank You Dinesh.

I will start a new thread; DNS Server not found (Anak)

 

[Reece212]

I have no idea what to change in the router configuration, could you possibly tell me?

 

[Dwarf]

In order to give instructions on this, we need to know the make and full model number (including the revision) of your router as, although routers basically operate in the same way, the configuration is generally specific to each router.

 

[Reece212]

Well, it's a Spanish router, although the settings are in english..

The make is Yacom
FW version: v.0.10.009
HW version: R01A
Name of manufacture: ARV4518PW-A-LF-LT

Sorry if it's the wrong details, it's on the back of my router.

Bump

Reece this maybe a stab in the dark, and I know Dwarf would not mean any intentional mis-direction

But..........

His Primary, and Secondary numbers don't look right, the:

Primary DNS Server: ....208.67.222.220.... Should be - 208.67.222.222...and
Secondary DNS Server: 208.67.220.222.... Should be - 208.67.220.220

There maybe instances where the third, and fouth set of numbers are transposed, but I have always seen them the same.

The "should be numbers" are what WindowsStar asked me to enter, and it hooked me right up!

So try the "should be's", and see if that makes a difference.



Here's a link to my thread:

Edit:
Also I did not change any router settings, the changes were made at the adapter settings.
Check the attachment in my post to see where.

Here are the 4 main OpenDNS addresses:

resolver1.dns.opendns.com 208.67.222.222
resolver2.dns.opendns.com 208.67.220.220
resolver3.dns.opendns.com 208.67.222.220
resolver4.dns.opendns.com 208.67.220.222

Hi Dwarf, I still don't understand

I borrowed this from:
OpenDNS > Support > Knowledge Base > Additional OpenDNS nameserver addresses

Additional OpenDNS nameserver addresses


OpenDNS nameserver IP addresses are:

• 208.67.220.220
• 208.67.222.222

Some routers and devices need a third or fourth nameserver IP address. Use these if necessary (identical service to the original two):

• 208.67.220.222
• 208.67.222.220

Updated: September 17, 2008

It shows their prefixes; 208 as compared to 220 are different than yours.

I realize these numbers are almost two years old, and you could have an updated set, but when I replaced the 208 with 220, I could not gain acess to the internet.

Could it be how your system is setup?

 

[Dwarf]

Oops... my bad. Corrected.

 

[Anak]

Awww....don't be so hard on yourself I've been know to make some doozies myself...Just ask my DW..


As I was looking around I came across an OpenDNS forum thread as late as December 8th, 2008,
See:
OpenDNS Community > Forums > restart OpenDns after HD crash

Where one user was using the 220 prefix, and didn't realize that ODNS had changed it to 208. So it was a valid number at one time.
He had some other problems that 208 didn't help, and I don't yet think are related to this thread.

After looking up 220.67.222.222 on IP Address Lookup It is presently a DNS out of The Republic of Korea :shock:

I have found another ODNS supplied by google if you don't mind working with them.
It's located 'bout fifty miles Northeast of Wichita, Kansas out in the middle of farm country.....gotta be the low overhead....

Zoom in on the map in satellite mode. The locator pin points to a farmstead. Its supposed to be faster, but I haven't checked it out yet.

IP Address Lookup
Primary:.....8.8.8.8
Secondary..8.8.4.4


May you have clear skies

Hi, thanks for the help, I tried changing the DNS servers to OpenDNS but still no help.
I have tried a lot of other servers, even my ISP's ones..

For some reason, I can't see an option to change my DNS Addresses in my router settings, and I can't connect to WAN, if that makes any difference.

I also tried Google's DNS a few weeks ago, still no help.

EDIT: I am using shared internet, the host computer is getting the internet using a wireless access point, and a ethernet cable is attached from the host computer to the router, and then another ethernet cable from the router to my laptop. If you need the host's ipconfig /all, just ask.

Hi Reece, your welcome.

Since your working off this host Pc, have you tried its DNS settings?
