Most modern routers allow you to backup the configuration of the router into a file, and then restore the configuration from the file when it's needed.
The backup file of the router usually contains important data like your ISP user name/password, the login password of the router, and wireless network keys.
If you lost one of these password/keys, but you still have a backup file of your router configuration, RouterPassView might help you to recover your lost password from your router file.[ Supported Routers ]
Due to large amount of router models available in the market, it's impossible to support all of them.
For now, RouterPassView supports a limited number of router models, and I'll gradually add support for more routers in future versions. Also, be aware that even if your router is not in the list, you can still try to open your router backup file with RouterPassView, because some routers are sold with different brand name, but they still use the same software/chipset of other routers. Here's the list:

RouterPassView doesn't require any installation process or additional DLL files. In order to start using it, simply run the executable file - RouterPassView.exe
After running RouterPassView, you can open your router configuration file by using 'Open Router Config File' option (Ctrl+O) or by dragging the config file from Explorer into the main window of RouterPassView.
If RouterPassView manage to detect and decrypt your router file, you should get a list of passwords/wireless keys in the main window of RouterPassView. If RouterPassView cannot detect your file, it'll remain empty.Method II: Text Mode (Ascii and Hex Dump)
If RouterPassView shows you a list of passwords, but you can't find the password or other data that you need, you may try to locate your password by switching to Ascii Text Mode (F3) or Hex Dump Text Mode (F4).
In these modes, RouterPassView decrypts the router file, but display it "as is" without analyzing the data stored in it.Method III: Using the 'Grab Password From IE Window' option
If you try to recover your ISP/ADSL/L2TP/PPTP/PPPOE/DDNS password, but RouterPassView cannot decrypt the configuration file of your router, you still have a chance to retrieve the password by using this feature, assuming that you have the login password of your router.
In order to use this feature, follow the instructions below.
1. Login into your router Web interface with Internet Explorer, and go to the password page that you wish to recover. This password page may look like this one:
As you can see in the above screenshot, the password field is filled with bullets, but if this password field really contains the password, RouterPassView will be able to extract it and display it on the main window.
2. Go to the File menu, and choose 'Grab Password From IE Window' or simply press Ctrl+G
3. If the router Web page store the password in the password field, RouterPassView will display the hidden password:
Be aware that some routers deliberately store wrong password in this field, and in for these routers, RouterPassView won't be able to recover your real password.[ Notes ]
RouterPassView supports limited number of router models. See above. [ Official Download ]
