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.

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.

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!

I bought a new Linksys WRT120N modem which is working great, but the wireless for some reason isn't working properly. My computer is able to sense the exsistence of the connection tho. I've tried using other computers to connect to it, and still the same problem, can sense but cannot connect.

I have a WRT120N and have been trying to set up priorities using the QoS under the tab Applications and Gaming. Everytime I "Save Settings" it does not save. It refreshes the page and deletes everything I just set up.
I did Live Chat and they told me it was my router. I returned it and got another one... Same problem

I'm using an Static IP adress and i'm using wrt120n router, but to connect the internet i have plugged the internet cable in the 1,2,3,4 (doesn't matter which one) slot. So now i'm just using the wirelss part of the router without "routering" if i can say so. When i put the internet cable in the Internet slot of the router, the laptop just cant connect to internet - it shows Unidentified network without Internet Access. I don't know what type of changes i have to make in the WEB interface of the router. I think i have to set the type of the connection - now is DHCP and may be to put my IP adress, DNS, Subnet mask in the router settings, but don't know how exactly. I've tried to set up the router with the CD-interface but same thing happened - Unidentified network when the cable is plugged in the Internet (yellow) port. How to set up the router to be a router, not just a wireless switch?

My roommate and I recently got a WRT120N to replace an older Linksys router that was exhibiting the same problems with less frequency. Indeed, the entire reason we got the new router was to fix these problems. Alas, they have become worse.Anyways, what's happening is that the router constantly resets itself. It does this every 20 minutes to an hour and doesn't seem to be related to how much traffic it's dealing with.It's not just the internet going down, it's the entire network, and not even just the wireless part. My computer has a wired connection to the router and, and I get told "A network cable has been unplugged" every time it happens. Then, if I look down at the router, I see no flashing lights, just the steady glow of the power light. It always fixes itself after 10-15 seconds, but it's very annoying. Certainly, playing games online or having a conversation on Skype is made more difficult.As previously mentioned, we replaced our older router because it was exhibiting the same behavior, but the new one does it with greater frequency. At the very least, the router does reset itself instead of needing us to cycle the power. The setup was slightly different with the old router: I was using a wireless connection with a WMP54Gv4 which I've had to disable since it bluescreens the moment it so much as sniffs a signal from the WRT120N?

Is there anyway to disable WPS on the WRT120N router?
All I can do is switch the "view" from WPS to manual configuration in the management console...this doesn't actually disable anything.Maybe I don't understand WPS security, but what's the point of using a 20 character WPA2 password if WPS has an 8 digit PIN that I can't change or disable?

I just bought a WRT120N to set up with my new Gateway Windows 7 64-bit using Cablevision cable internet. When I go through the steps from the CD to install, the wizard does not find the connection. When the internet is plugged directly into the computer, it works fine. If I have the router plugged in first and then run the install CD, it picks up the router as an existing router but I can't get it to install

I plan on replacing my linksys BEFW11S4 wireless router with a new linksys WRT120N wireless router. Should I completely remove and unplug the old router before inserting the startup CD and beginning the installation process for the new router?

I have several computers and printers connected to a WRT120N router which is connected to 10mpbs DSL. The computers are all running WIN7 and are hardwired to the router. On the one PC, it keeps losing network connection. I've tried upgrading the router's firmware, reset, etc. to no avail.
I think it may be related to the same IP address being assigned to multiple machines connected to the router. Is there a way to set specific IP addresses to each item connected to the router to see?

I can't access the web based setup via 192.168.1.1. I've had this problem since I swapped to Static Ip from PPPoE. I changed internet provider and now when it type 192.168.1.1 in the browser it says Internet explorer can't show the web page. I've tried Crome and FireFox but with the same result. I followed the instructions in [URL] but to no result.

I replaced a WRT120N router with a new one thinking that the old one was damaged. During setup, the router wasn't recognized. I used the same connection for a line from the internet to my LAN connectin and the line works fine. Connecting through the router is no good.

I am considering to purchase a Linksys Wireless router, but I just don't know which one to select.There are so many different types that seem to have very similar (if not equal) specs.If I just limit myself to the WRT120N, the WRT160N and the E1000, they all have 4 ethernet ports (10/100), and they all support 802.11 b/g/n for the wireless part.Obviously they all promise a blazing performance, and wireless coverage throughout the whole house, without (many) blind spots.But if their specs are the same, why are they different types?

Several days ago there was a huge storm, and I think a thunder burned the WAN port of my linksys wrt120n router. Everything else is working good, I can detect the local network but I don't have internet. My internet connection is also working good. My question is, do I have a possibility to use some of LAN port like a WAN? I'm only using 2 of 4 LAN ports. It would be very useful because it's a pity to buy another router just for a not working WAN port.

I am trying to manually setup a WRT120N router. I am using my laptop (hard wired) for the initial setup. Okay, everything is working fine until I unplug the ethernet cable and try to go wireless. Will not connect to my network. I am also having this problem with all my other devices.
I had everything running fine on a WRT54G, I just wanted to try out the WRT102N. I did change the SSID name form what I was using on the WRT54G.
