  1. Hey there,

    My DNS still does not work, even after doing this. I opened a terminal and typed in ping and it says “request timed out” – I know very little about computers, but this is the second internet connection spot where this has happened. I’m using google chrome, but IE does not load either. Any suggestions/thoughts?

    Thank you!

    • Hi Kirsten,
      What type of internet connection do you have at your place? Is it ADSL or Cable Broadband? Is Adsl, then is your modem connected to a router?

      • Hi, I’m having trouble with the same thing. DNS lookup failure and it is happening after I setup a wireless bridge connection. The wireless network seems to be created by the bridge router and SSID shows up fine, you can even get connected to it on mobile devices but no internet and I also have a PC connected via ethernet to the bridge router which is where I’m getting the DNS loookup failure. I believe it is probably a configuration error causing the DNS problem and the no internet problem but I can’t figure it out. Any help would be appreciated, thanks.

        • Hi Aj, Try changing the DNS address. Check this post to find the best dns servers for your computer. Once you change the dns,restart your computer. Clear cookies, cache history etc from your browse.

          Go to CMD and perform a dns flush.. ie. ipconfig/flushdns

          Disable add-ons and try private browsing.

          If your using Chrome, Try to uninstall and install newer version and see if it works

  2. I tried everything and it still won’t work

    • Did you try to install chrome? If not, uninstall and try reinstalling the latest version.

  3. Thanks man …great help. thank you very much

  4. Yo Yo Anish. A big to you. It was getting buggy out there on the www, but your clear and concise video put the prance back in my step! Watch out world. Up Up and away…………

  5. I won’t use Google chrome because ‘G’ is big brother gone bad but I do use Iron that has the same browser engine and it too does fake DNS lookups that are ten digits long and I block these using a custom DNS server that I wrote myself

    It would be good to have a way of stopping Chrome from doing fake lookup’s and if I can spot them in my DNS server then so can others so lets no pretend its all about polling for redirects from public DNS servers
