ARRISSURFboard S33Modem / gateway · Web	http://192.168.100.1 (opens in a new tab)	admin	Password on the device label	The password is derived from the device: username admin, password = last 8 digits of the serial number printed on the label, with a forced password change on first login. Some early firmware accepted admin/password. No universal factory default. Manufacturer (opens in a new tab) Recovery & reset instructions Open a browser to http://192.168.100.1 to reach the S33 web manager (this is a cable-modem diagnostics/settings page, not a Wi-Fi router). Log in with username 'admin' and the last 8 digits of the serial number on the bottom label, then create a new password when prompted. If locked out, wait 10 minutes after too many failed attempts, or factory reset by holding the recessed Reset button on the back for about 10 seconds; after reset, log in again with admin + last 8 of the serial.
ARRISSURFboard SB8200Modem / gateway · Web	http://192.168.100.1 (opens in a new tab)	admin	Password on the device label	Modem, not a router. Older firmware shipped with admin/password, but current firmware uses admin plus the last 8 digits of the serial number (from the label) and forces you to create a new password on first login. There is no universal admin/admin. Manufacturer (opens in a new tab) Recovery & reset instructions The SB8200 is a modem only (no Wi-Fi), so 192.168.100.1 is a diagnostics/web-manager page, not a router settings page. To reach it, open a browser to http://192.168.100.1. On current firmware the username is 'admin' and the password is the last 8 characters of the serial number printed on the modem's bottom label; you'll be prompted to set a new password on first login. To factory reset, press and hold the recessed Reset button on the back with a paperclip for about 10 seconds until the modem restarts, which reverts the admin password to the last-8-of-serial default.

How to reach your router

Connect your computer or phone to the router’s Wi-Fi or an Ethernet port.
Open a documented login address. If it does not load, look for the Router or Default gateway address in your device’s network settings.
Match your model and hardware revision to the table. Use the device label or your setup password when the model has no shared default.

Admin password or Wi-Fi password?

The admin password opens the router’s settings. The Wi-Fi password connects a device to the wireless network. They may be different, and an ISP or cloud account can be separate again.

If the password does not work

Check capitalization and the device label, then use the manufacturer’s password-recovery instructions. A factory reset erases settings and may require ISP setup details; follow the instructions for your exact model.
