The SBR-AC1900P also allows for a wireless guest network (in addition to a wireless primary network). The guest network provides access to the Internet, but prevents devices from communicating with primary wireless and wired connected client devices. The guest network also includes UPnP and Firewall functionality.
The SBR-AC1900P supports 2.4GHz and 5.0 GHz Wi-Fi frequencies simultaneously. Each frequency has it's own SSID (Service Set Identification), which is the name given to the wireless network of the SBR-AC1900P.  The 2.4 GHz frequency supports 802.11 b/g/n wireless clients, while the 5.0 GHz frequency supports 802.11n wireless clients only. 802.11n devices will generally perform better in the 5GHz range.
The Guest Network is disabled by default. This document describes how to enable the guest network, and how to configure the guest network without wireless security.Â
WARNING:Â With this setup, the wireless functionality of the SBR-AC1900PÂ will provide no encryption for the wireless guest network.

 - On the Wireless - Guest Network page, select the desired frequency tab to modify (2.4 GHz or 5 GHz).
NOTE 1: Choosing the Wireless Interface only determines which frequency settings are desired to be modified. The 2.4 GHz and 5 GHz frequencies are already enabled simultaneously by default.
NOTE 2: The 2.4 GHz frequency supports 802.11 b/g/n wireless clients, while the 5.0 GHz frequency supports 802.11n wireless clients only.  802.11n devices will generally perform better in the 5GHz range.
NOTE 3: In this example, the 2.4 GHz frequency has been selected to modify.
 - Click the Guest Network drop-down menu and select Enabled.
- Enter a new wireless network name in the Guest Network Name (SSID) field.
- Click the IP Network drop-down menu and select Guest or LAN.
