Modem

I need the username and password to access the modem so I can change the wifi password thank you Max Cook.

Should normally be written on a sticker on the bottom of the modem. If you have changed it to something else and now forgotten it then you will need to do a factory reset (Hold a pin in the small whole on the side). This will restore the default password and login.

If you can't find the username/password listed on the sticker. The default username is normally set to:

Username: Admin

Password: Optus, Admin or Password 

This may differ depending on the model of modem you're using.

the default login details for any of the recent Sagemcom modems are:

username: admin
password: whatever the default wifi password is
