Modem / router usernames & passwords

These are the factory-set passwords and usernames that allow access to your settings, WiFi and network configuration using your internet browser. Most routers / modems also have this information labelled on the underside of the modem/ router.

  • Default username: admin
  • Default password: password

These security details should not be confused with your Primary OptusNet username or password or your WiFi security details. More on these is below.

Why aren't the default passwords/ usernames working?

If you've previously changed the username and / or password and forgotten them, you'll need to perform a factory reset of your modem / router and then use the default passwords / usernames above to have access.

Factory resetting your modem/router

A factory reset usually involves holding a recessed button down for a few seconds. Reset buttons are normally located on the rear or underside of your modem/ router. You'll find factory reset steps for Optus supplied modems in their respective user guides; you can download yours from this article.
