Hi Community Members’
I hope you are in good health. I have reset to factory default router RB750gr3 several times but it is still asking me with the password. Please help to resolve this issue.

Check if there are no space(s) after admin
You do not really reset the device, or the device has a default script that set the password or change the admin accont name.
Use Netinstall, and, on this occasion, I advise you to install 6.48.7
May peace be upon you.
For other users: Forget about the system default password, which is present from v7 onwards and the user is using v6.
