RouterPassView might help you to recover your lost password from your router file. The 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 lose one of these password/keys, but you still have a backup file of your router configuration.
[advt]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.
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.
