DNS Lookup Failed / Server Not Responding
Dec 20, 2011
I have a Windows XP laptop and a Windows 7 desktop. The desktop has no wifi support, I had built it myself. To get internet on my desktop (used for games), I had connected my laptop to the pc, and the laptop picked up wifi from my AT&T gateway in another part of the house. ( I can't move the gateway currently) I have been wanting to connect the desktop to a router/repeater/bridge that would pick up my gateway signal, therefore eliminating the use of the laptop. I also have an Xbox right next to the pc, so I din't want to get an adapter because then I would have to purchase two, so I picked up a a wireless n router with 4 ethernet ports. ( then I could connect both systems using 2 ethernet cables) [URL] I knew when purchasing the router that it had repeater/bridge support. Currently, I have it configured as a wifi bridge. I can connect to it via my laptop, on the wireless networks page, it shows my gateway signal, and the bridge/router, so I connect to the router. It says I have excellent connection, but I can't connect to the internet? Using Google Chrome, it says DNS lookup failed. I can't get on any website, only the router's config page, which is 192.168.1.1. I also connected the router to my pc, and when troubleshooting it says DNS server not responding, may be non existant or incorrect?

So I just got a new Acer ultrabook and it was working fine until a few days ago. It keeps saying the DNS lookup failed. I've tried everything I can. I made sure it wasn't chrome, doesn't work in Firefox. Reset the modem, did a DNS dump, set the DNS to a 888thing. Utorrent is connecting to the internet fine and I can connect for random periods of time. If I do trouble shoot over and over eventually it starts working. Everyone else in my house gets internet even my sister with the same computer and model.

dns lookup failed, on all web browser (IE, Google, Firefox). I did ip and winsock reset, did networking ins safe mode, it will ping my ip address but will not ping any other address. My computer (running Vista home premium) says that I have internet access but it does not work. This happened on one computer and then on another one about 6 days later and they both are wired to a router.

My WLAN has been working fine for the past 6 months. Recently it started connecting and disconnecting itself. ANd now it will only connect to the network but wont give internet access. I can connect to the same router using an ethernet cord. And I can connect to the wireless network using my phone or other computer. There are no driver updates for my network adapter, and I tried reconfiguring the router. That worked for a short period of time, but now I have the same issue. I tried a system restore back to before a recent virus software update to see if maybe that update was causing the firewall to block something.

Well first of all id say im pretty good at these types of things as they have happened to me so many times. But i cant figure this one out. Yesterday my internet just went out. All of the lights on the modem are still on everything says it should be connected but just doesnt work. When i try to open webpages it says DNS Lookup failed. Called tech support they are sending me a new modem atm, but i have 2 other ones around that i have tried and they say that im connected to the internet, but nothing same lookup error and everything so i do not think it is the modem. Flushed dns, manually entered the isps dns , Dont know what else to try at all.

Iv had this problem with two wireless repeaters now. when im connected to just the router, i am able to access the internet. however when i plug in and set up the wireless repeater ( the latest one is a amped wireless sr300) it works for a few min and then i get a "DNS lookup failed" when trying to access sites. this repeater replaced a hawking hwren1. which would work for a few min and then lose the network.i believe this is a problem with our internet connection into the house, but could it be a caused by the router? (wrt400n) our isp says its not their problem and that its our router, but this is the 4th one in under a year.

Whenever I try to goto a webpage within any browser,despite me being connected to my network(though 1 received packet to every 20 or so sent packet ratio) it tells me that DNS lookup failed. I had a similar issue on my other pc that I use more often,though connecting through WIFI momentarily resolved the issue,before I returning to wired,where everything has been fine. My other pc however has no wifi adapter. So ive been stuck.

I have just gone through hours of tech support with my ISP and still cannot seem to get online. Problem is the same as recent posts by jerguy1928, with message "DNS lookup failed...." coming up in Google Chrome. Both IE and FF just say cannot connect.Running Windows 7 on laptop. I have tried alt DNS settings (Google and others), all the CMD suggestions, disabling firewalls etc, etc! Other computer in house connects just fine.Ping works fine. Really, there appears to be no reason to not be able to connect - since I am actually connected!

I've been having an issue with my internet connection, which has been getting a lot worse over the past 1 month. I purchased the WRT120N about a year and a half ago, and occasionally observed dropped connections, but it was no big deal. Over teh past month or so, however, it seems like I get the "DNS lookup failed" error about every 15-30 minutes. Every time, I have to disconnect and reconnect my computer to my router. In addition, I will be disconnected from XBox Live. This problem may occur every 5 minutes or every few hours.
I have updated the firmware on the router. I have reset the router, and have reset DNS 1 t0 8.8.8.8 and DNS 2 to 8.8.4.4. THe network is configured as a DHCP. The X-Box has a wired connection, and my laptop experiences this problem whether I use a wired connection or a wireless one.

I have a problem with my internet. Not so long time ago I bought new TOSHIBA laptop with Windows 7. At the start everything was OK but after few days internet connection started struggling. Troubleshoot says that DNS server is not responding.There are a couple others laptops on the same network and it seems that just me have this problem.The problem - Skype, torrents are working OK. The problem is with connection to internet sites via my internet browser. It doesn't matter it's IE, Mozilla or Google Chrome, I have the problem with all of them. Sometimes the problem disappears and everything is working OK but usually I have the problem and can't connect to one or other site.

I've take a lot of measures so far to try to resolve this but I believe I have changed a lot of essential things in the process. I am running Windows 7 and my antivirus software is McAfee. [code]

I am having an issue with my netgear router dg834g
last night my router just stopped working when i was on the internet. I looked at my router and the power light and tick were flashing. After disconnectibg the power a few times this continued so i called it a night and left it disconnected.
Tonight i turned it back on and all looks fine on the router but on the pc it will now not connect and says the dns server isnt responding.
Maybe its a problem with my internet provider (orange) so not sure but its frustrating lol. Dont know a lot of the techical stuff i was using it fine for over a year withoit any problems.

For a while now every time I started up my computer I wouldn't be able to connect to the internet. When I used the Windows Network Diagnostic tool, it said "the DNS server isn't responding". Last weekend I seemed to have solved this with DNS jumper after trying everything (flushing etc.). I tested a torrent and got speeds up to 2.1mb/s which I have never gotten before. Even the other members of my household noticed faster internet speed. This worked up until late Sunday when my internet decided to crash. The problem with starting the computer is gone, but everytime I I tested another torrent and get speed of 2kB/s and while I am downloading, I can't surf the web on that computer. I tried port-forwarding for uTorrent which seemed to work a bit. Download speeds jumped to 20kB/s for about a minute then fell back down to 2kB/s. I saw some forums saying it was there anti virus so I disabled the P2P shield on avast! and that did work as well, so I uninstalled it and got a new anti virus and the speeds were still around 20kB/s then plummeted again

I get the message "dns server isn't responding" several times per day. If i get the message, nothing can get through to the internet (smartphones, laptop, vita, friends smartphones, etc.) If i reset the router, i can access the web again. Or if i wait for 2 minutes.
This is my setup:
Cable modem connects to D-link 615. Laptop is connected with a cable in D-link 615. All my wireless stuff is connected via wireless D-link 615. My cable modem is also connected directly to my ps3. I'm running windows 7 on my laptop.

I have been having some trouble with my internet for awhile now. It fine one second and than it will get really slow and eventually stop working. When I troubleshoot to see what the problem is it either gives me DNS server is not responding or default gateway is not available, sometimes it will give me both. It says it fixes the default gateway problem but it will show up again 5 minutes later.
Here is my ipconfig /all

I'm having an issue with my wireless connection.I was connected fine to my wireless internet on my desktop perfectly fine. I then attempted to connect to Xbox live at this time and that also worked fine.The connection began to get a little flaky (kept losing connection) so I reset my modem while they were both still connected.When the modem came back neither was able to connect.My other laptop, iPhone, and iPad also can no longer connect to the wireless.Windows troubleshooting tells me my DNS server is no longer responding. I'm assuming the desktop connection and Xbox connection are trying to connect to the same thing due to my reset, but I can't figure out how to fix it.

So up till about a week ago my internet connection has been fine. Then all of the sudden it will "cut off" for about 5-10 mins and then be fine again. It happens randomly, sometimes it won't happen for a couple hours and then sometimes it happens 2-3 times in a hour. Funny thing is that it says I am still connected to the internet and infact if I am able to log into like MSN or skype or I am playing a online game, I can still play those games or chat. However, if I am not signed on to msn, skype, etc....during when I can't browse the internet, I can't log into those services. I thought maybe it was my pc, but my ipod touch and roommate's laptop experience the same exact issue as they are connected to my router. The error the pc is giving me is "DNS Server isn't responding.".

I have cable internet with time warner, who provided me with a basic ambit modem. It works if I connect it directly with my PC. But if I try to route the connection through my netgear router (eg. connect modem -> router -> PC), I don't get internet access. The troubleshooting tool tells me that "DNS server isn't responding".

My laptop is connecting to BT Business Hub fine but with "No Internet Access". All I'm being told is "DNS server isn't responding". I've tried all the command prompts I've found and tried "Obtaining DNS server automatically" as well as the default numbers on some forums but nothing is working.I can connect to this same network on my iPad with no problems and this laptop can connect to an alternative wifi as well.

I have Broadband Internet and TV through Time Warner Cable. In the past week I suddenly began to lose stations on my cable box from what seemed to be a loss in signal so I had tech support come out to take a look at the problem. Turns out the problem was the wiring in the cable box outside the house. The wiring was over a decade old and had been damaged by water and ice over many winters. Tech support guy replaced all the wiring and the cable box is back to normal!However, after sitting down to use the Internet afterwards my connection kept "dying". Every ten to fifteen minutes or so the connection would seem to die for a minute or two.
All devices connected to the router either wired or wireless experience the issue at the same exact time. Windows diagnosed the problem as "DNS Server Not Responding". Now my router setup has been working for years, and nothing has been changed, so I thought maybe it could be related with the issue with the cable wiresHowever, researching the DNS issue on Google makes me think it's just coincidence.
I rebooted and power cycled the modem and the router. The issue persists. Updated router firmware. The issue persists. I changed my DNS settings to use OpenDNS. The issue persists. Changed DNS settings back to automatic. The issue persists. So I disconnected the router and plugged the modem directly into my main PC and the issue was completely resolved! Hooked up the router again and the issue popped back up after ten minutesRepeated all the troubleshooting steps and the issue persisted through them all.

I have a dell xps L502X with windows 8. My network adapter was replaced last month. My DHCP is enabled. My DNS Server reads 192.168.1.1 and it's a home/cable/DSL connection so from what I've read that's right. I've set my IPv4 and IPv6 to automatically detect the DNS server and IP address to use. I've tried to reconfigure the computer to the wireless router, but when I go to set up a new network no networks pop up even though many networks pop up for me to connect to on the right of my screen.
All of my other devices are connected and working fine. That was the background and what I've tried to fix for my problem. When I try to connect to my home network it says it's a limited connection meaning I have no Internet access. When I run the trouble shooter for the network, Internet connections, and network adapter the only one that has an issue is the network one and the issue is that the DNS server isn't responding.

I got an internet from provider (which is LAN cable sticking from the wall) - and it works fine when I connect via LAN cable - when I write the IP Address, Subnet Mask, Default Gateway, and DNS servers on the LAN adapter and create a PPPoE connection with username and password. I want to do the same but wirelessly. I have an ASUS RT-N10 LX wi-fi router - and connected the cable from the provider to the WAN slot on the router. Then I have accessed the router from my laptop [URL] - and configured everything as it was on my laptop.
IP Adddress: 192.168.17.191
Submask: 255.255.252.0
Default Gateway: 192.168.16.1
DNS1: 192.168.1.250
DNS1: 192.168.1.10
Wireless network works fine, the default gateway is pinging - but DNS servers are not accessible. As a result no internet connection available ( Moreover - when I want to ping the DNS (ping 192.168.1.250) - I tries to get a response from other location 192.168.1.3
