Keep getting Server not Found

Help, Everytime I browse the internet I frequently get this Message "Sever Not Found" and the webpage cannot be loaded I have to hit the RELOAD button so many times for it to load. This only happens when I am connected to my laptop wirelessly and when I connect it directly I do not have this problem at all. I have tried all kinds of ways I can think of - Resetting both modem and router - renewing my ip. I am all out of ideas, and when I connect this directly to my modem I do not have this problem at all. Any Idea. Thanks I have the WRT54G ver. 4, I already updated its firmware.

Hi,
As you have already updated the firmware to latest version, try changing the advanced settings of wireless network. Do these steps:
Connect computer to router directly.
Open setup page of router by typing http://192.168.1.1 in browser's address bar, and typing password as "admin" and no user name.
Go to wireless tab and change wireless network name to anything other that linksysChange channel to 11.
Go to advanced wireless settings and here change beacon interval to 50, fragmentation threshold to 2306, and RTS threshold to 2307.
After this power cycle router and modem and observe connection.
It should be improved.

In Firefox, I keep getting "Server not found" error - CONSTANTLY!

Two days ago I started getting the "server not found" error, off and on, daily. It is happening on both my desktop iMac 10.7, and my Windows 7 laptop. I keep having to hit the "Try Again" butting, and sometimes, several times, before a web site will finally launch. The only two extensions I have on both, are the Adblock Plus and the Last Tab Close Button, both of which, have been installed on said computers for months and months and months.
I went in and changed a setting to the "auto detect proxy setting", hoping that would work, and it did not.
I have Firefox version 21 on both computers, and it seems the problem started shortly after this latest Firefox update, and at the SAME TIME on both computers.
I do not have virus protection on my iMac, nor on my Windows 7 laptop, at the moment, but I have run online software to check for anything, and no issues, so I believe, it is not that which is the issue.
The firewalls on both computers are working fine and no issues there either, I have not changed any firewall settings, on either computer. It couldn't be the firewall, in my opinion, because this annoying error message started happening on BOTH of my computers, at the same time; I work on my iMac in the morning, then switch to my laptop in the afternoon, and same issue continues on both, and started at the same time, on both.
Is there something broken in Firefox from this last update of the browser?
Does anyone have any suggestions as to why both computers are having this issue, at the same time?
I have not tried using I.E. yet on my laptop, I rarely have ever needed to use that browser, and I hate it, so I don't use it.
Any help or suggestions, would be appreciated.

I followed those steps, but clearly some steps are missing. How do you "enable each extension one at a time"? The only choices I see in Safe Mode are "disable" and "remove."
And why is it that every other update to Firefox breaks Firefox? I've had to install add-ons just to be able to use it in Windows 8 with a touchpad.
Now that I think of it, it doesn't even matter any more. After years of Firefox loyalty (even after Firefox users have dropped to 28%), I'm off to download Google Chrome (up to 52%). I'll miss Firefox, but not the on-again, off-again performance.

How to fix error loading webpage - keep getting "server not found" repeatedly & have reloaded firefox and tried everthing - quite annoying and did not have problem when I first began using firefox - I am ready to try another browser

How to fix "server not found"

Does this happen on all websites? If so then you may have to update the permissions in your firewall application to allow the new Firefox.

Firefox won't open...keep getting "404 not found" WHY? HELP

firefox won't open...keep getting "404 not found" WHY? HELP

The 404 message usually indicates a web page can not be found. If you are seeing that message in Firefox then Firefox is up and running but either having problems connecting to the web or not finding a specific target page. Sometimes the address may be wrong, sometimes the site may not be available.
Have you written this message whilst using Firefox on another computer ?

On the problem computer, if it is a Windows machine it will probably have Internet Explorer, does that work ok ?
Is it one particular website you are having a problem with, if so what is that site, and what is the web address as written in the location bar. If it is many pages give at least two examples please.
Copy and paste the location bar contents into your post
* Keyboard key '''Ctrl + L''' (press the Control key hold it down than press the L key) that will highlight the location bar content, do that while trying to use the web page
* '''Ctrl + C''' copies the info to the 'clipboard'
* change to the message you are writing '''Ctrl + V''' pastes/inserts content at mouse cursor in your message

Frequently get 'Server not found', have tried all articles solution, what now?

Frequently get 'server not found' when accessing web sites, no particular websites just randomly all sites, clicking 'try again' always resolves. I am thouroughly sick and tired of this error and no working soloutions! Have tried 'about:config' settings; pipelining, script_run_time, ipv6. Have tried reinstall of Firefox and update of firefox. Have allowed firefox in my firewall which is 'Comodo' and have deleted entry and re-allowed it again. Have tried firefox proxy settings on all choices of settings. These things do not fix the problem. I cannot find anymore information or solutions to try, I have searched everywhere and everything and tried all the things Ive found as mentioned above. What is the problem? Can it be resolved? How can it be fixed?

A possible cause is security software (firewall) that blocks or restricts Firefox or the plugin-container process without informing you, possibly after detecting changes (update) to the Firefox program.
Remove all rules for Firefox from the permissions list in the firewall and let your firewall ask again for permission to get full unrestricted access to internet for Firefox and the plugin-container process and the updater process.

Why do certain of my Firefox windows start getting "Server not found"?

Several times a day, one or more of my many Firefox windows gets into a state where it gets "Server not found" whenever I try to browse to a new URL. Internet Explorer is not affected.
I usually run Firefox with ~4 windows and more than a hundred tabs. The problem sometimes affects only one of those windows. Sometimes I can solve it by closing and then reopening the window. Sometimes I can solve it by closing and then reopening Firefox. Sometimes I can solve it by rebooting.
It's hard to say when exactly this started. The computer is only two weeks old.
I have experimented with the solutions discussed here (played with my firewall, verified that I am not using a proxy server, network.dns.disableIPv6, network.dns.disablePrefetch): http://support.mozilla.org/en-US/kb/Firefox%20cannot%20load%20websites%20but%20other%20programs%20can

Our email keeps saying server not found - it is up and running and we can access it from other computers just not the imacs, our email keeps saying server not found - it is up and running and we can access it from other computers just not the imacs

Our email keeps shutting down and saying server not found. It works fine on all the PCs but not our iMacs. Any help would be appreciated. We just downloaded the new LION - would this be an issue?

I feel like I'm getting closer. First, the connector on our cable didn't fit snugly. Tug it slightly and it lost contact. I put a new cable on the server and now it seems more robust. Server Admin opened faster, anyway.
In the Console, I'm seeing some Kerberos errors:

This server is bound to Active Directory (using Directory Utility -- don't know if I need to do it elsewhere?) and I'm not sure what was trying to authenticate at that time.
My error messages for "server not found" have gone away for my iChat client, but now it just pops up the authentication window over and over when I try to log in. I'm wondering if there's something missing in the server binding?

When I click on Mozilla Firefox I get server not found. When I ask for help I get server not found. Without my intention visual bee is in background.

I recently responded to a prompt to upgrade Mozilla Firefox and started seeing visual bee in background and got lookup for browser safeguard.com.com failed. Can't get into Firefox. My version is 3.6.12. Help requested. Thanks Keith

It is possible that your security software (firewall, anti-virus) blocks or restricts Firefox or the plugin-container process without informing you, possibly after detecting changes (update) to the Firefox program.
Remove all rules for Firefox and the plugin-container from the permissions list in the firewall and let your firewall ask again for permission to get full unrestricted access to internet for Firefox and the plugin-container process and the updater process.

Getting "server not found" errors randomly. If I reload the page comes up fine. Why?

I'm on a Mac running 10.6.5 and using Firefox 3.6.13. All of the sudden pages I visit all the time are coming up with "server not found" errors, but when I refresh the page comes up fine. Sometimes the page loads, but in html code and all jumbled.
How do I fix this? Very annoying. I've been using Firefox for years and it's never done this. Nothing's changed with my connection or settings.

You detailed the situation very well dezi.
Amazing that so many people have this problem yet NONE of these so called "AWESOME" developers deem it important enough to address the issue.
I still have the exact same lame problem as you with 3.6.whatever it is now.
There are quite a few of these random"Server not found" threads scattered around here,all with a mounting number of "people have this problem"
On my old MacBook Pro, which runs 3.5.16, I have no such issue.
After 6 weeks of exhaustive research the only thing I have found is a fix aimed at PC users in which you alter the about:config settings (not that it would work for us or that if it is even possible) that affect something called DNS fetching. I am not a computer person so all the jargon about do this-do that goes over my head. However, to get this solved I will learn what it takes.
I hope we get some real answers soon
(and none of that "empty your cache and cookies" garbage either)

Desktops get "Server Not Found" errors with WRT160N

I'm sharing my WRT160N with 2 laptops and 3 desktops. My laptops connect to the internet ok... drops now and then tho... but my desktops frequently get a "Server Not Found" error. After repeated "try again" clicks, it eventually connects again. Any ideas??

Try this ;
Open an Internet Explorer browser page on your wired computer(desktop).In the address bar type - 192.168.1.1 and press Enter...Leave Username blank & in Password use admin in lower case...
Under the Setup Tab...reduce the MTU value to 1300 and save settings.
Also reduce the card speed of the dekstop... (assuming it is window XP)..Click on the Start button >>> Control Panel >> Network Connections >> Right click on the ""Local Area Connection"" icon and select properties-Here click on the "Configure" button- Click on the "Advanced" tab- In the "Property" box highlight Link speed and duplex/Connection type/Network or Media type- And in the "Value" box select 10 Mbps half duplex/ 10 base T/10 base half mode and click on OK.. Now restart the computer.

When trying to open firefox I always get "server not found".

After downloading Firefox I cannot get it to connect to the internet. I always get the message "server not found." I have tried all the "fixes" suggested online but without any luck. This is a new download and I have not used Firefox before now.

A possible cause is security software (firewall) that blocks or restricts Firefox or the plugin-container process without informing you, possibly after detecting changes (update) to the Firefox program.
Remove all rules for Firefox from the permissions list in the firewall and let your firewall ask again for permission to get full unrestricted access to internet for Firefox and the plugin-container process and the updater process.

When i load a page i get "server not found", when i click retry it loads properly, what can i do to have firefox load page first time

When i load a page it often tells me "server not found". When i click on retry most of the time it works. How do i fix it so that it works the first time.
== This happened ==
Every time Firefox opened
== a couple months ago

You either have an extension that causes that issue or some security software (firewall) is causing a delay.
See [[Troubleshooting extensions and themes]]
Also make sure that Firefox gets full unrestricted access to the internet.

Why do i keep getting 404 not found nginx/1.0.8

Need help can not open a game keep getting 404 not found

its on face book slotomania it goes to the site then changes ?
I know very little about playing Facebook games, but in general terms, if a site loads at least partially and then suddenly redirects to a different site, it's likely to be a malicious script of some kind that a hacker has managed to get placed on that page. After it redirects and you see the 404 error, what is shown in the address bar in your web browser?
