DNS Lookup Failed On All Web Browser?

Oct 24, 2011

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.

System Keeps Saying DNS Lookup Failed

Sep 26, 2012

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.

No Internet Access - DNS Lookup Failed

Oct 13, 2011

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.

DNS Lookup Failed With A Wireless Repeater

Jun 3, 2011

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.

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?

Error Message On All Browsers - DNS Lookup Failed

Dec 31, 2012

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.

Error Message In Google Chrome - DNS Lookup Failed

Jun 20, 2011

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!

Linksys Wireless Router :: DNS Lookup Failed WRT120N?

Dec 22, 2012

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.

Repeated DNS Lookup Failures?

Nov 8, 2012

My netbook keeps getting DNS Lookup Failure messages. This happens about every 20 minutes, give or take, though sometimes it can go longer before the failure. I can "solve" the problem by quickly repairing the network connection, but that's tedious. It happens only on my laptop and not on my housemate's desktop (wired connection) though he did say that it happens to him on his laptop as well. In looking around I thought the problem might be because i'm using Chrome, but it happens on Firefox and Opera as well.

Cisco :: RV016 DNS Lookup Failure

Apr 19, 2012

I manage a small business with 10 computers running off my network. They are all connected to the internet through a RV016. We recently created a new website and purchased a new domain through In Motion Hosting. I have a randomly reoccuring issue, usually in the morning, that seems to resolve itself after a couple hours on it's own. I have dealt with tech support from In Motion Hosting and my ISP who have both come to the determination that the problem lies within my gateway.
 
When I attempt to log on to my companies website [URL] my browser is unable to locate the webpage. Also, if I try to access the website for In Motion Hosting [URL] or to access our webmail [URL]I am unable to do so because the DNS lookup failed. I can view any other web page on the internet without a problem. I can not ping or tracert either website successfully, however when I called In Motion Hosting and got the IP addresses for the two I was able to ping and tracert them without a problem.
 
As I said the problem happens randomly and seems to resolve itself within 2-8 hours. However we are unable to access our email during these "blackouts" which is becoming a huge problem.
 
Is there a setting within the RV016 that might be causing this to happen?

Host Names Not Resolving NS Lookup Works

Apr 21, 2011

I was thrown into trying to fix a friends pc being told that the internet wasn't working.What I've found through some messing around is that I am able to pull up websites with the ip address but trying to use the domain name give a "Host Not Found". Similar error when trying to do a ping. However doing an nslookup will pull the ip's for a domain. I've done the dns flush, the netsh commands that are floating around to no avail.

DNS Lookup Failures While Connected To VPN With Sierra Wireless AirCard313U

May 14, 2012

For more than 6 months I have been happily using a Sierra Wireless AirCard313U to connect my Win7 Pro (64-bit x86) laptop to the internet, and using another corporation's VPN (Citrix Access Gateway) as a contractor - so networking problems ARE my problem.

Now what happens is: DNS failures halt my internet browsing and any hope of RDP'ing into the corporate LAN whenever I connect to the VPN while using the AirCard (its a USB/cell modem device). The DNS lookups and RDP'ing works fine when I'm using the VPN with my wifi.

What changed recently:Installed Connectify software Uninstalled Connectify software (didn't work w/AirCard) Installed VirtualRouter software Uninstalled VirtualRouter software (didn't work w/AirCard) Installed Sierra Wireless' AirCard Watcher software (manager app, may have included updated drivers for the AirCard) Re-install Connectify software (now worked w/AirCard)Uninstalled Connectify software (DNS problem had appeared)

I've tried removing ISATAPs, running these commands & rebooting, to no avail:netsh int ipv4 reset reset.log netsh int ipv6 reset reset.log netsh winsock reset catalog

Right now, connected to VPN via wifi my ipconfig /all looks like this:

Windows IP Configuration
Host Name . . . . . . . . . . . . : W7
Primary Dns Suffix . . . . . . . :

Browser Using Too Many Connections?

Sep 10, 2012

It started when I couldn't connect to a specific website for 2 days. I had to change my IP to get on again, and when I did I got a message from the admin saying that I had been blocked automatically because my browser was using upwards of 200 connections at a time. He made me check all the browser settings for it, and everything was still set at default. I didn't download any program or add-on, I did nothing special. It started out of the blue. I did virus scans, I reinstalled firefox and opera (the browsers I use). At this point I have no clue what the problem is.

Some Pages Can't Load In Any Browser

Jan 28, 2013

Let me start with what the problem is. Some pages like google open very fast while some takes a lot of time and sometimes do not load at all.I tried pinging certain websites along with mygame website mabinogi.nexon.net and the request timed out. I tried a few solutions

1) Switched browser and it didn't seem to work (Even the client I use for the game Mabinogi disconnects every 5 to 10 mins)

2) Tried changing the DNS to OpenDNS and it still didn't work

3) Tried using network on safe mode with networking and still I got the same result. That is some pages take a lot of time while others load soon.
