• Error: "DNS server not found" when you try to access the internet.

  original title: network WIFI DNS connection issues

  Hi all

  This is my weirdest experience with WIFI connections so far. So let me explain.
  I have several WIFI connection to my modem/router that work very well, 2 phones and 2 laptops work just great, wirelessly.
  Now I have this new ASUS wireless adapter to my PC and it gives me a headache, and the ASUS support... Well, what kind of support?
  When I turn on my pc, my pc connects to the router with full connection bars. But there is no internet, I'm getting DNS SERVER NOT FOUND, this happens every time when starting of the pc. But when my pc has already started and then I reset the router, I get internet with good working DNS and then everything works. But of course, when then restart my pc again, it loses DNS and I can restart the router once more...
  I have tried everything I know, manual setting of DNS does not work, renewing the ip and dns cmd of hot flashes do not work either.
  My setup
  ------
  Windows 7 Professional x 64
  ASUS PCE - N15 11n Wireless card
  DHCP enabled
  Dns and ip automatic (ip4/ip6) parameters
  ------
  I really hope that you guys can help me, it drives me crazy and the problem continues to exist for a month now.

  Hello Serellyn,

  Have you tried to change the wireless channel that your router is running at? There may be interference that could prevent the internet connection:

  Take a look at step 6 in this article. He further explains this problem as possible:

  If you need assistance to change the settings of the specific router, you will need to contact your router manufacturer or your internet service provider.

• Work around for server not found problems on FF36

  I found a work around for all people with server not found problems with FF36.

  If you manually set your DNS network adapter to an external DNS server (as opposed to your local ISP) then the problem disappears. I set mine to use the google DNS servers:

   Preferred: 8.8.8.8
   Alternate: 8.8.4.4
  

  No idea why this works, but it is 100% success on my desktop PC, whereas before I could not connect to a Web page with FF36 without updating the multiple page and a lot of frustration, although FF35 was fine and back to FF35 turnover was as beautiful.

  Something has changed in FF36 and how it manages the DNS or the mode of operation with certain network cards.

  There is nothing to do with the Add - ons, profiles or software firewall as I tried all these things and that the DNS change makes a difference. I even copied on a full profile and directory of program files to work for Mozilla on my laptop which saw no problem and the problem still exists on the desktop, which is why I started watching the network adapater since everything between the working PC and no work was identical.

  I hope that this will help the developers to identify the real cause of the problem and fix it in the next version.

  AG - your problem looks different you had FF36 work.

  Considering that the problem of many of us that when we spend FF35 in FF36 we get a lot of server is found errors when you try to load Web pages.

  Sometimes they load and then they stop loading and then if you click Refresh a lot that they sometimes then charge again, or you have to wait a minute or two and then they load.

  For some reason any using an external DNS server {see # 698286 answer _{~ J99}} has stopped this problem completely, as does return to FF35.

  We need an expert on to Mozilla DNS resolution to focus on this. [*] ^{See my note under ~ J99} Seems to me that you use an external DNS server adds some latency to name resolution and maybe this is necessary for the network card in the PC that encounter this issue to resolve the addresses of Web page.

  Obviously something changed in FF36 FF35 to cause this problem. I'm open to Mozilla contact me by E-mail if they want me to try something else to help pin it down.

  change Note the John99
  Mozilla can consider WHETHER we are able to provide evidence to support this. We must be able to complete a report of bug with right steps to reproduce (STR). Developers should be able to see themselves the problem before we can expect to focus on this.

• Firefox server not found problem

  When I opened my new links on Google search results pages, sometimes I got the pages 'server not found '. I had to refresh twice like that to get the pages loaded. I searched online solutions and I had tried to disable the antivirus, turn off DNS prefetching, uncheck ' web Sites Tell I won't be subject to a follow-up ", disable IPv6 in Firefox, restart it with disabled modules, but they have all failed. I found that there is no problem to use Google DNS. Help thanks.

  Start Firefox in Safe Mode {web link}
  While you are in safe mode;

  Type of topic: preferences #advanced< enter > in the address bar.

  Under Advanced, select General.
  Find and stop using hardware acceleration.

  Search web sites secure. Are there problems?

  Then restart.

  When you click a link, first check in the small storefront
  at the bottom of the screen. Is it correct? After clicking, you end
  to the top on this page?

• Why does Firefox Mac returns 'Server not found' for a website but Safari on Mac same load site without any problems?

  The financial company Web site www.gmo.com will not appear in Firefox 32.0.02. Server not found is the only result. Safari loads Web site without any problem and Firefox for Windows computer in the House support the site without problem. All the other sites I have access, including banks, Amazon, etc. loads normally.

  What/why the Mac of Firefox version would not be able to to connect/load this site?

  The company of people told me that no one else has reported this problem and other people in my company can access the site. And they cannot reproduce the problem.

  My ISP provider could not see anything from their point of view. And access all computers to the modem/router in the House everything without any problems.

  Anyone have any ideas on what would cause this or how to go about troubleshooting?

  Thank you for your time.

  Looks like it's something on the computer. There are cookies that must be removed individually from the Firefox profile.

  To do this, go to the Firefox Menu, tap Preferences, then tap privacy and then delete cookies or cookies see the. You can search the sites that gives you problems and remove them. Restart Firefox.

  It could also be that you add a DNS server for your connection. 8.8.8.8 is google, but I don't know if this would affect given that the server is not found, not that there is no link, that's why it does not sound like a connection problem, but a cache problem. Use the Profile Manager to create and delete profiles Firefox

• I tried everything, but I get "SERVER NOT FOUND TRY AGAIN" when I try again his connects. What is the prayer of the problem. N ".

  I tried everything but keep getting "SERVER NOT FOUND TRY AGAIN" when I try again once it normally connects. What is the problem please

  This can have several reasons:

  first make sure that your firewall/security software allows firefox to fully access the internet.

  then you can try the solutions (proxy settings, the change of dns server) provided in this support thread: https://support.mozilla.org/de/questi.../704934

  If this does not help, also try disabling ipv6 as described here: https://support.mozilla.org/en-US/kb/Server%20not%20found?s=server%20not%...

• Server not found (well Yes.) Another)

  Hello wonderful people to support,

  I know that this fault has been raised countless times previously. But for me? Currently a problem.

  My "Server not found" error since frequency increased significantly in moving on Windows 10 x 64 (from Win 7 x 64), composed at the same time to install a new version of Firefox in early June and subsequently updated to current 47.0.1.

  At first I blamed the sites themselves (the server down?), but as he became more persistent, I tested the site with another browser and everything was fine.

  I tried almost all the suggestions listed in the FAQ section section help for this type of error (including disabling the firewall, disabling all browser extensions & add-ons, Cache, DNS Prefetching, compensation for malware Checked). The only step I still have to take is "Reset Firefox" because of its recent nature resort.

  Often, a Web site that are not accessible due to "Server not found" can properly be consulted a few moments later (within 30 minutes) without adjusting a single setting of the browser or system.

  It is not a constant problem that 95% of the time Web sites to connect without a problem, but it is a problem.

  Yours faithfully, Jason

  Have you tried flushing your DNS? Your DNS converts URLS to IP addresses. She recorded these IP addresses in a table so that they are accessible later. Flushing your DNS will delete this table and can solve the problem.

  If it does not help the issue, please try to reset your Internet Options in Windows and reset Internet Explorer. I know that sounds strange, but sometimes not valid settings in the Internet Options or Internet Explorer can prevent Firefox to work properly.

  Please let us know if you are able to solve the problem.

• Server not found

  EVERY Web site I click on give me this error on my Mac Book Pro page:

  Server not found

  Firefox can't find the server at www.weather.com.

     Check the address for typing errors such as ww.example.com instead of www.example.com
     If you are unable to load any pages, check your computer's network connection.
     If your computer or network is protected by a firewall or proxy, make sure that Firefox is permitted to access the Web.
  

  What is rong?

  You have security software that would block websites?

  Try disabling IPv6 (also check other possible causes).

• try to download firefox, rpet server not found, no problem with IE or AOL, tho

  Cannot understand this, because I can't have with IE or AOL - no problem connecting. When I click on download it opens a download window, but then nothing happens. When I see a log (don't remember where it was), it's when I see the server not found. I am NOT focused on the technical side, so... Thank you!

  Hey,.

  What browser you try to download from Firefox? You're going to Mozilla.org to do (and if not, you know what to do now!)?

  Thank you!

• Can I go back to the old look error messages 'server not found '?

  After the Firefox 32 update, I noticed that the "server not found" error messages look differently now. I don't like the new look, so I wonder if you know an add-on that restores the old look. I tried to search for him, but I don't know the name of these error messages, so I don't know what search phrase I should use.

  Thank you very much for your answer. The solution in the thread link you to seems to be a bit too complicated for me, so I guess I'll have to live with the new error messages (unless the add-on you link is updated to work with latest versions of Firefox, but that seems unlikely). Thank you anyway for your help, however.

• Server not found error message

  Download constantly 'Server not found' when passing to the homepage of any other page. Example, Firefox can't find the server at support.mozilla.org

  What home page? I guess that you didn't write your message on the wrong
  Firefox. There are several things that could be the problem.

  Some problems occurs when your Internet security program has been implemented.
  trust the previous version of Firefox, but not more acknowledges your
  update as being approved. Now how do I solve the problem: to allow
  Firefox to connect to the Internet

  • Make sure your Internet security software is up-to-date (for example, you are using the latest version)
  • Delete Firefox to list your program of trusted or recognized programs, then add it again. For detailed instructions, see
