I have a really small network in my house, with only three computers. Recently I've experienced my computer disconnecting from the internet for 3-5 seconds, and it only happens two or three times a day. I get this Warning message in the event logs:

Event ID 1014, Warning Name resolution for the name dns.msftncsi.com timed out after none of the configured DNS servers responded.

The website dns.msftncsi.com isn't a constant, it's been a few random sites (i'm guessing whatever site i'm on at the time of disconnect.)

My network consists of a windows 7 Desktop, Linux mint laptop, and a macbook pro. My router is a Netgear N600, and here's my output of ipconfig /all

I've been troubleshooting this for a while, and really am out of ideas. I have only noticed the problem on my windows 7 desktop, but that could be because my laptops are normally only on at work or school. Thanks in advance, and let me know what other information might be needed.

This question came from our site for professional system and network administrators.

    
I still haven't gotten this fixed, and have found this same question in several places on the internet, with no resolutions. The windows 7 forums has this question also, with no resolution, so if anybody thinks they have an answer, please feel free to try :) –  Slimmons Aug 2 '13 at 4:01

Try setting the DNS on your router to Google's Public DNS: https://developers.google.com/speed/public-dns/

Here's a youtube video of where to find that in your router's settings if you are having problems: http://youtu.be/beTp_YYNOxo

Hope this helps.

I'm making 8.8.8.8 my secondary DNS on my router. I'll let you know if it helps. Let me know if you think it would be better to have googles DNS as my primary DNS. Right now my primary DNS is set to what my isp said it should be. –  Slimmons Jul 30 '13 at 5:10
    
Personally I use Level 3 as my DNS, but you can find the best for you as well as compare your ISP DNS service with other free alternatives (Google Public DNS, Level 3, OpenDNS) using code.google.com/p/namebench or sordum.org/7952/dns-jumper-v1-0-5. DNS Jumper is much simpler and also handles changing your DNS for you and making backups. Namebench only benchmarks different DNS providers. –  djfdat Jul 30 '13 at 5:54
    
How would you recommend choosing the DNS best for me? By doing trace routes to them to see which is faster, or by which is physically closer? (which should be the same thing), or another way? –  Slimmons Jul 30 '13 at 20:53
    
DNS Jumper can automatically detect and apply the fastest DNS for you, and is the method I'd suggest. Namebench with make actual DNS requests to the DNS server and give you more detailed statistics as to what happens on each DNS server (min/max/avg time, inaccurate DNS addresses, and based off browser history). –  djfdat Jul 31 '13 at 1:57
    
Nope, still same problem after I changed the DNS servers. I wonder if it could be something with my ISP? My disconnects generally happen about the same time every night, around 8:00pm-10:00pm. Is there a possibility that their protocol for changing IP's around is messing with the connection? I have found this problem in many other places, normally in forums for businesses, but I haven't found any with a solution. –  Slimmons Jul 31 '13 at 2:20

As it turns out, my disconnects were from my ISP not having a large enough pipeline for my neighborhood, and they also had to replace the switch I was on. The errors make sense now that I know what the problem was, but I really didn't expect this since I couldn't even tracert to my ISP (which was because the initial switch I was on was going in and out at the same time.) Thanks for all of the help, but my ISP has fixed both problems now (they are a super small ISP, with like 10 employees total).
