The SBR-AC1900P is a wireless router that provides secure high-speed Internet connectivity to the wired or wireless network devices on the home or small business network.  It is compatible with Cable, DSL, and FIOS service. Â
When installing the SBR-AC1900P to a Wi-Fi cable modem, the Wi-Fi cable modem will then need to be setup as a pass through device by disabling routing, wireless, and firewall features to allow the SBR-AC1900P to be the primary Wi-Fi  router and firewall. This will allow the SBR-AC1900P to handle the connection to the Internet.  Please contact the manufacturer to determine how to configure the Wi-Fi cable modem as a pass through device.Â
This document contains the following sections:
CAUTION: To better secure your network, ARRIS recommends to change the default Admin user name & password and the default wireless password immediately after connecting to the Internet.
