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?

A way to brute force in your router could be used from everywhere and to hack all similar router protections... so even if there is a way, I think you shouldn't get it here! Obs: -1 for the above reason –  laurent Jun 28 '11 at 14:04

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

You are asking for a backdoor/crack into a router admitting (at least in the earlier versions) that it was against the wishes of the owner. I think some people find that objectionable. –  soandos Jun 28 '11 at 17:57

Put simply, while in general a way to break into routers would make me uneasy, as it is easy for it too be used unethically, to say how to do it in a way that the person who set the password would not know would seem "too close" for lack of better words to having no ethical grounds. I do not know reasons why you need to do this, and you are correct in saying that I have no right/need to know. But the post on meta that I quoted basically gave me my reason. It seems (at least to me) to fall under the "Enough information to determine ethics" catagory, and not in the "it is OK way." Sorry. –  soandos Jun 28 '11 at 19:09

coming from a hacker myself. all these people say "its not right, your trying to hack. they just dont know any way to do it... dont worry about them. Anyone who has an ounce of knowledge will know that you dont need a program to get around a router password. depending on how much access you have to the router. i need more details. are you connected through an RJ-45, or are you trying to connect wireless to the router. –  user155973 Sep 3 '12 at 0:21

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.

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

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.

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...

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.

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
