Sudden DNS errors

Hi All,

I am having issues with my network suddenly. I can get online, and for the most part pages load after a few moments. But I am (always) getting the DNS errors/page will not load the first time.

Not to be a totally noob but I have updated my drivers, defrag if needed and clean browser history on a regular basis.

Let me know what you need to help me figure this issue out.

Thanks in advance.

The first thing we probably need is an ipconfig listing. You can open a command prompt and type ipconfig /all to get the listing. You can copy that from the command window (right click -select MARK to highlight and hit enter to copy) and paste. If there is any private type information displayed, you can edit that. You could also attach a text file, if you choose, by using the paperclip on the Advanced Replies window.

You could also use this command to make a text file on your desktop. Replace the user name, of course.

ipconfig /all > C:\Users\YourUser\Desktop\config.txt

You can also copy from here and paste into a command prompt.

To open a Command Prompt, Winkey and type cmd then enter.

Thanks Salt!

I have attached the copy (hopefully) of what you needed. I am not understanding why this is happening suddenly. We installed a new Comcast modem/router and the wireless was super fast. Now, if feels like something is stalling it out. This is not happening to my roommates laptop. I am somewhat worried that my HDD is going. I did a chkdsk test and it took up towards an hour/hour 1/2 (where a few months back) it only took a minute.

Looks like you only got the bottom of the report. Maybe using the other command would be best since I saw one the other day that was 5 pages long. You can extend the Command window to see the entire readout if necessary.

.....I was rushing it. Sorry. This should be good. Although it's not 5 pages....

Ok, you are connecting with your Wireless. It shows DHCP if off, and an address of 10.0.0.5 and a mask of 255.0.0.0. You set these up manually because you did not want to use DHCP?

Normally, at least in many installs, the DNS server is the same as the gateway. But this depends on your setup and equipment. Where did you get the DNS addresses you are using 75.75.75.75 and .76. You might try the Google public servers to test, 8.8.8.8 or 8.8.4.4

If none of that helps, you might try changing the mask to 255.255.255.0, even though Windows puts in the one you have. Don't know if this will help, but you could test.

This Google site, and I am not recommending Google, shows the IPv4 and IPv6 DNS server addresses...

I have no idea what DHCP is and why it is off. I entered those addresses from the command prompt per reading ways to fix the DNS issue.

I will try the above addresses and turn on DHCP - not exactly sure how but hopefully Google will help. I also changed my DNS addresses to 208 67 222 222 // 208 67 220 220 and checked "Obtain addresses automatically" and removed the ones I manually entered. I will check out the link you noted as well.

Dhcp is when you router/gateway assigns IP addresses to your network adapter, assuming the router has been enabled to do so, and it is normally that way by default. It assigns the primary IP address, the Default Gateway, Subnet mask, and the DNS servers.

If the problem started before you changed your current settings, we need to see the IPconfig for your original setup.

After you make the changes, you will probably need to disable and then enable your wireless adapter so it will resync.

Yes, I just read about it. Just another way of obtaining the addresses automatically- which was the original settings.

I changed these addresses after experiencing the slow connections and DNS errors thinking it may help. It..did not.

I tried the 8 8 8 8/ 8 8 4 4 and it seemed to slow it down again. The 208 67 222 222208 67 220 220 seem to be a bit faster but not by much.

Any idea on what else could be the issue? I have scanned with Eset/Malwarebytes and it states not infected.

Scanning with Microsoft Essentials now and uninstalling it after knowing that I can not have two security programs.

Thanks so much so far. I don't want to do a factory install if I don't have too. I am sure that is extreme at this point?

(Microsoft Essentials found a Hacktool / Keygen in my system which I have now cleaned. Could this be the issue?)

And why did Eset not pick this up? I have been told running two anti virus programs will cause issues and possibly cancel each other out. Is this true or can I keep both Essentials and Eset?
