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.

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.

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.

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?

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!

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 . . . . . . . :

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.

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?

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.

I have Cisco VPN 3000 in main office which provides VPN tunnel to the remote site (PIX 506). In main office we have Domain Controller as well as DNS/DHCP servers.I ran into the issue where DNS reverse lookups are not working from main office to the remote computers:
ping remotecomputer.mydomain.org - works fine from main office and resolves to appropriate IP address ping -a IP address - from main office returns nothing.attdns.com
From the remote computers, both forward and reverse lookups are working fine.

I was trying to setup a Nexus (5596 running NX-OS 5.1(3)N2(1)) to use the "ip ospf name-lookup"command that I am using on IOS-based routers. Unfortunately this command does not appear to be supported on NX-OS and I cannot find a replacement.Is this another feature that's left out of NX-OS?

I have a fairly large home (>5000 sq ft) with multiple levels and some "dead spots" in the extreme areas. I would like to have a fantastic wi-fi signal through the home for access to my home network for my family and internet for guests. I have Fios with a 50/20 mpm with a "g" router. I also have purchased 2 repeaters (ampedwireless.com) and installed 1. Recognizing that it appears to have created a different network, so this isn't what I want to do. Then I went back and purchased 2 access points. I need to have an "hardware solution" in my theater (basement) as well as in my bedroom (3rd floor).

I recently bought a new D-Link DIR 615 but I dont get adequate range in the rooms farthest away from the router. I have an old D-Link DIR 634M router which I'm told can be used as a wireless repeater. I went through several articles that describe connecting the two routers through a LAN cable. However is there a way to do the same without using a cable of any sorts?

As I am more of a hardware guy and pretty clueless about networking, I thought I'd come here because I am pretty frustrated right now.So yesterday, I got an Amped Wireless SR10000 Repeater for Christmas. I had it set up and working with no problems. However, this message did pop up when it was finished:
I ignored it (stupid me) because I didn't know what to do. The connection worked fine for a while, but now a day later, the connection keeps dropping. I would assume it is because of this.I did a bit of research and it seems like setting up a static IP will fix the problem, but I have no idea how to do that.

We have a home network which consists of one Motorola wireless router and 3 PCs. Two of the PCs connect directly to the wireless router without any issues, however, my PC dosent have a built in Wi Fi card so am using a TP Link wireless N USB adaptor.... so as you can imagine the signal is still very poor. So I have bought a TP Link AP and have it set up in repeater mode to increase the range of the router and thus improve my connection.
Now this works great in the short term as I get full signal, but the problem is the signal tends to drop out every 20 mins or so.Now, originally we were recieving an IP address conflict message which I thought was causing these drop outs, but I have rectified this by using MAC address filtering on the AP (think the AP was connecting to someone elses PC in our block of flats), but the drop outs still continue.
I have a static IP set on both my PC and AP and DHCP enabled on the Motorola router, I have also tried changing the Motorola's channel and moving the AP to different places but the story dosent change.I am a right noob when it comes to networking and have got this far by reading manuals, google searching and trail and error so dont know what else to do.

I want to extend the range of the wireless network using a 601 (or just a relatively lowend N series). Can I just set a 601 as a repeater? Not seeing anything in the manual that provides instructions. I don't have the ability to cable the routers together. I want to do it all wirelessly if possible.

I have spent countless weekends trying to configure the WAP 4410 as a wireless repeater. From what I see the instructions and help screens seem to be incomplete or the WAP is not capable of this function even though it is available.It will not connect to the modem wirelessly as a repeater. I have tried numberous settings including the same channel and SSID without avail. As soon as I disconnect it from the wireless modem it will no longer connect to the internet.I have an older WRT 610N which will connect to the modem as a repeater so I don't think it is at the modem end.Searches have indicated others with a similar problem but I don't see any viable solutions except to buy and connect to another WAP 4410.Contacting Cisco for suppor by chat t has been pointless. Either they are not available when I am or they are clueless.

I would like to ask for assistance on how to configure one unit WAP4410N access point to work as repeater to one unit WRT120N wireless router.
As a background, I had one WRT120N already in my house before I bought one WAP4410N as advised by a Linksys guy. I wanted to wirelessly extend the signal of my WRT120N wherever its signal is so low around my house. The WAP4410N should work as repeater to WRT120N.
I already configured WAP4410N to work as repeater by enabling all the choices in its wireless AP mode like the “wireless WDS repeater” and the “wireless client/repeater” but to no avail. I successfully setup a similar scenario before using the old pair of one WRT54G and one WAP54G. I replaced the old pair with the newer one ( WRT120N and one WAP4410N).
Is the tandem of WAP4410N and WRT120N can be configured technically as like as what I wanted? Do I need to upgrade the firmware of both devices? Did I miss something in the configuration?
