Windows 7: Windows not connecting to the primary DNS

Windows not connecting to the primary DNS

Hello.

So I haven't used one of my PCs for a week or so, and when I come back my internet doesn't work.
I get the yellow triangle with the ''!'' sign on the internet icon.
Troubleshooting says the Windows is not connecting to the primary DNS.

What I've tried:

- Disabling and enabling the internet connection from Local Area Connection window.
- Restarting the modem.
- Unplugging the UTP cable from the PC and connecting it back.
- Unplugging the modem from power, plugging it back.
- Reinstalling Ethernet drivers.

None of these worked.
I've contacted my provider, and they recommended me to reinstall the ethernet cables, so I did so. It didn't work.
So they said afterwards that it is an internal problem in my PC, and that their parameters show that everything is all right.

What else can I do?

Thank you!

To better assist you can you please follow this tutorial - Basic Requirements Before Posting your Networking Thread. This can help us identify what may be causing your issue.

It maybe a fault with the DNS server that you are using and you may need to change it.

DNS is a protocol used to translate hostnames into IP addresses so a computer can talk to it.

For example, www.google.co.uk is the website we enter in our browsers yet computers can't actually use that as they communicate using IP addresses. To translate this and find out what the IP address is it uses DNS.

An analogy I typically like to use is to compare it to a phone book.

In your phone you may have a contact called Bob and with that have a phone number in that contact. When you dial Bob your phone doesn't actually go to your phone provider and dial "Bob" but rather it looks for Bob in the phone book and then dials the phone number associated. The same thing with computer networks

For example, www.google.co.uk has the following IP addresses associated with it.

By looking at your IPconfig we can see what DNS server you have configured and whether or not you may need to use a different one. You see, if a DNS server goes down then your computer will essentially lose internet connectivity as it is unable to translate hostnames to IP addresses.

1. Is this a wired or wireless connection issue?
Wired.

2. Who is your Internet Service Provider (ISP)?
Romania provider - UPC

3. What type of Broadband connection are you using?
Don't know to be honest.

4. What is the exact Make and Model of your Modem, Router or Modem/Router Combo
Ubee Modem

5. What is the Name of the Anti-Virus, Security or Firewall Software installed from the problematic computer - BitDefender Internet Security 2014 (Licensed)

My IP Config:

Here's what I get if I disable the connection through Local Area Connection and then I repair it as an administrator through Troubleshoot:



Here's what I get if I use ''Diagnose'' through Local Area Connection when the yellow triangle is present on the icon:

Lets try something....

Can you please follow this tutorial - DNS Addressing - How to Change in Windows 7

When you get to step 7 please enter the following addresses:

Preferred DNS Server: 8.8.8.8

Alternate DNS Server: 8.8.4.4

See if that resolves your issue. If Windows is saying that the issue is with DNS then this should resolve the issue. If not then we need to investigate further.

Hope This Helps,
Josh

I will try it Josh, but as I read, this will give me high pings, as I have to connect to the closest DNS server which is located in London.
I play many multiplayer games like Battlefield 4 - at a competitive level, so this won't help me at all.
Isn't there a way to ask my ISP to set me another DNS around my location?

Remember, DNS is a one time thing once a resolution has been made it is cached and the server is never contacted again until the next reboot.

The high ping will only happen on resolutions of hostnames and FPS games will not be affected by this as there is no DNS usage when streaming therefore you wouldn't be contacting the server.

You could ask your ISP to change it on their end however chances are that they won't bother and at best maybe charge you for it.

So then where will I be disadvantaged if using that DNS?
'Resolutions of hostnames', you said. What does that mean?

When browsing the web or sending an email. But for these tasks having a high ping doesn't make an impact. This forum is located in America and your ping is probably much higher reaching this server than the DNS one.

When streaming video from YouTube or Skype or playing online games you won't be completing DNS because the computer will already know the IP address of the server.

DNS is only used to get an IP address and that's it.

Where are you in the world? I may be able to find an appropriate server closer to you if it helps. First though it would. Be good to see of the new server changes actually resolve the issue.
