I have tried logging into the 10.0.0.1 site using the default login (admin password) and keep getting authentication errors, i have tried holding the reset button down for over a minute but it seems like its only causing the gateway to power cycle as wifi devices can still login using the same password. I have no clue what the password for the routerlogin is as all my normal ones are being rejected.
Depends on which device you have though. Also, if you're resetting the ideal length of time to purge the bad un/pw is holding the reset button for 30 seconds.
Look like it is a Comcast supplied gateway device if the access IP address is 10.0.0.1
The default username is indeed admin and the default password is indeed password if it is.
