How do we get or bypass the password of a router (Linksys Wireless-N Home Router WRT120N) if the default username and pass doesn't work?

Not at all relevant. I am not not answering your question because its you. I have nothing against you. Its your question that I think does not deserve an answer here. In addition I think this meta page is more on point. –  soandos Jun 28 '11 at 15:10

None that I know of. Your father may have been the one to set the password, and if so, if you change it, even by resetting it, he is going to know.

I think the better question that should be answered here is this:

Is there ever a situation that I would need to "hack" into my wireless router without reseting all the settings?

The answer is simply no there is not. Here is the reason why.

  • If you don't know how to setup the settings on a router, then you shouldn't be trying to hack into it.
    • There is a high probability that you'll break it after getting into the router as you don't know what you're doing.
    • If you're afraid/don't know how to set it up then why would you want to hack into it in the first place when all this would do is give you access to settings within the router

Manufacturers made it difficult for individuals to 'hack' into a router without resetting all the settings for a good reason. Password/usernames could become compromised. Redirect, and malicious software could be remotely installed or deployed. Forcing the reset of the setting helps to mitigate these risks.

Even though original question is very controversial. I strongly disagree with your statement. Here is an example for you. Few years ago I moved into a flat that had a router for common internet access. At some point one of the neighbors has asked me to change some settings. No one new admin password. Router had no model or make printed on it so no way of figuring out default password. Resetting would no help as no one had a user manual. Do you think bruteforcing it was still irrelevant? (and yes I know that this is not the situation OP described, but I am just disagreeing with your statement) –  smc Jun 18 at 12:52

You can try the wifi network backup manager to backup your wifi data , it stores it in xml format . Open the file , it might have the passowrd , though i am not sure if this would work . Please update here if it works .
Alternatively you can check the saved passwords of the browser that you father uses to check if the password is stored there.
All other ways that come to my mind are not ethical ;)

the wifi network backup manager does not store the router password (the link at 192.168.1.1) but rather the network password.. what i wanted is the router password. heys you can share any unethical methods since it's fully ethical. by right that's my router you see –  Pacerier Jun 28 '11 at 14:58

Nirsofts WirelessKeyView may help you.

WirelessKeyView recovers all wireless network security keys/passwords (WEP/WPA) stored in your computer by the 'Wireless Zero Configuration' service of Windows XP or by the 'WLAN AutoConfig' service of Windows Vista, Windows 7, Windows 8, and Windows Server 2008.

This is irrelevant. OP is asking about admin password to router's web interface. –  smc Jun 18 at 12:55
    
The term "web interface" hasn't been mentioned :) –  SHOUBHIK BOSE Jun 18 at 13:46
    
If you read through the original version of the post, then you will see the line "I'm thinking there's some program that could brute force it's way into 192.168.1.1". You can work it out from there. –  smc Jun 18 at 13:48

Look into brute force attacking. That is the longest but apparently most successful way to get through, assuming they haven't used a long random combination of letters, numbers and symbols (Like administrators should, but don't more often than not).

So in short, just reset it and start from scratch.

Accessing the router requires a web browser. So if you have previously accessed your router through your browser, there may be a chance that the password was saved. In most browsers you can display saved passwords. Here's what to do:

  1. Open your browser
  2. Look for the "options" action (depends on browser)
  3. Look for security
  4. Look for Saved Passwords (firefox for sure, not sure about chrome/IE/Opera)

Look for your router's default IP address - typically "192.168.1.1" or "192.168.0.1". Click the "show passwords" button (should be on the screen somewhere) Look for the username and password.

With any luck should be set...

The default password to a router is usually pasted on the router itself. If you don't have access to the router, then you really shouldn't be trying to access it at all. (I.E. ... if you're sitting on the sidewalk trying to log onto your neighbor's wifi.) A hard reset of the router will usually work; if not, it's possible that the default password has been changed, at which point you either find it in the paperwork or call the network provider. All of which necessitates, of course, you being the person who could rightfully ask for the password in the first place.

The user mentions in his original question that he did not wish to perform a hard reset of the router to factory settings. Typically, attempt to constrain answers to the parameters set by the question. In this case, the question is poor and does not solicit particularly good answers. –  Will.Beninger Jun 3 '13 at 22:17

Typically login to browser interface is protected by html form with POST method. Now I say typically because it is not always like that. However if this is the case then bruteforcing is easy.

You can either write a code in any language you know that will send POST requests with generated credentials (or using dictionary). Or you can download the software that will do it for you. One good program that works on both Windows and Linux is called hydra.

Maybe someone has written the graphical front end to it, but when I was using it, there was only command line interface.

I will not be posting links here and since SU is not a hacking forum I will also say this : Use this software only for testing and experiments and with educational purposes. Never brute-force or otherwise attack resources that you are not entitled to access bacause this is against the law
