It’s common to forget your username and password or not know your router’s default one. If you are having trouble logging in to your router, there is a good chance that your router's username and password are still set to the default settings.
Follow these steps in order to recover or find out your router’s username and password.
Default username and password are specified in the documentation that accompanies the router. The default username and password are marked on a label along with the router’s serial number and login address. If this label or the documentation is unavailable for any reason, go to SOLUTION#2.
All routers have a default username and password. If you can’t get that information, find out your router from our Default Router Passwords. Write down the username and password and then go to your router IP address (follow this article in case you don't know your router's address: How to find your router IP address).
If you have no luck with SOLUTION#1 and 2, you can reset the router.
(Warning: Resetting wipes all configuration changes done on network settings, forwarded ports, parental controls, and custom passwords on the router)
To perform a factory reset:
Now you can log into the router using your default username and password.
You can also forward ports without knowing the password using Universal Plug and Play (UPnP). Several routers allow applications to instruct the router to open ports. UPnP-enabled routers will automatically open the ports. If an application supports automatic forwarding of ports, the users are likely to find the option in connection settings alongside the port configuration. NAT-PMP establishes network address translation settings and port forwarding configurations in an automated manner. UPnP PortMapper enables you to forward any ports you like.
