If you are just trying to get into your router why not reset it to default with the reset button and then look up in the manual or online what the default settings are for user and password? You cannot really recover the forgotten password or user ID.
And if you are trying to find your network password to connect a wireless device, it is in the router configuration page. To access that type in the router gateway address into a connected computer and then the user ID/password for the router. Then look in the wireless security section for your security passkey.
