The Access Control feature in the SBR-AC1900P determines whether wireless clients are allowed or denied access to the wireless network. When enabled, Access Control can be set up in one of two ways:
- Allow access to everyone, except the clients listed.
- Deny access to everyone, except the clients listed.
Whether if access is allowed or denied is determined by the client's MAC address.  For instructions on how to locate the MAC address in Windows and Mac operating systems:
NOTE: Even if a client is allowed by Access Control to connect to the wireless network, it will still need an encryption key to connect (if encryption is enabled for that wireless network).Â
Access Control is disabled by default. This document describes how to configure Access Control.
Â
To Configure Access Control
Â
- Launch a web browser, such as Internet Explorer, Firefox, or Safari.  Enter http://192.168.0.1 into the address box, and press the Enter key. The Login page appears.

- MAC Restrict Mode -Â Click the drop-down menu and choose the desired setting.
- Disabled - Access Control is off.
- Allow - Denies access to all wireless clients except those clients listed in the MAC Addresses fields.
- Deny - Allows access to all wireless clients except those listed in the MAC Addresses fields.
 - MAC Address List - Enter the MAC addresses of the devices to allow or deny access in the fields.
- If MAC Restrict Mode is set to Allowed - Enter the MAC addresses of the wireless clients that will be allowed access.
- If MAC Restrict Mode is set to Denied - Enter the MAC addresses of the wireless clients to be denied access.
 - Click the Apply button.
NOTE: In the example below, the MAC Restrict Mode for the Primary Network has been set to Deny.  As a result, all wireless clients are allowed by Access Control to connect to the network except for one device, which has a MAC address of 00:16:CB:00:59:B6.  This device will be denied access.Â
