All FiOS routers come from the manufacturer with a default user name and password. Each manufacturer can use a different combination of user name and password as the default. If you didn't change the default password when you set up your router, you can use the table below to look up the default user name and password for your router.
|Verizon 9100 EM||admin||password*|
|D-Link DI-624||admin||Leave field blank|
If you changed your router password during setup, it's very important that you find where you wrote down your new security settings. If you can't remember the new password and can't find the paper where you wrote down the new security settings, you will have no choice but to reset your router to the default settings. This has serious consequences. When you reset your router, you not only reset the password to the default value, but you also delete all your network settings. This includes the SSID and network security key. That means you will have to reconfigure your network and all the wireless adapters on your home network computers.
* - If you didn't change your router password during installation, it may have been changed to the serial number of your router to improve security. You can find the serial number of your router on the label affixed to the back or bottom of your router.
