Chapter 1 Introduction The AR-5381u is an 802.11n (300Mbps) Wireless ADSL2+ router. AR-5381u has four 10/100 Base-T Ethernet ports, a Wi-Fi Protected Setup (WPS) button and a Wi-Fi switch button, one USB Host, and is backward compatible with existing 802.11b (11Mbps) and 11g (54bps) equipment. The AR-5381u ADSL2+ router also provides state of the art security features such as 64/128 bit WEP encryption and WPA/WPA2 encryption, Firewall, and VPN pass through.
1.2 Application The following diagram depicts a typical application of the AR-5381u.
Chapter 2 Installation 2.1 Hardware Setup Follow the instructions below to complete the hardware setup. BACK PANEL The figure below shows the back panel of the device. ADSL Connect to the ADSL port with the ADSL RJ11 cable. Ethernet (LAN) Ports You can connect the router to up to four LAN devices using RJ45 cables. The ports are auto-sensing MDI/X and either straight-through or crossover cable can be used. USB Host Port (Type A) This port can be used to connect the router to the print server.
FRONT PANEL The Wi-Fi & WPS buttons are located on the bottom-left of the front panel, as shown. WiFi Switch Press this button to enable/disable the wireless LAN (WLAN). WPS Button Press this button to begin searching for WPS clients.

Check your OS support documentation for further details.
3.3 Login Procedure Perform the following steps to login to the web user interface. NOTE: The default settings can be found in 3.1 Default Settings. STEP 1: Start the Internet browser and enter the default IP address for the device in the Web address field. For example, if the default IP address is 192.168.1.1, type http://192.168.1.1. NOTE: For local administration (i.e. LAN access), the PC running the browser must be attached to the Ethernet, and not necessarily to the device. For remote access (i.e.

Destination IP address Enter destination IP address. Destination Port (port or port:port) Enter destination port number or range.
5.6.2 NOTE: MAC Filtering This option is only available in bridge mode. Other modes use 5.6.1 IP Filtering to perform a similar function. Each network device has a unique 48-bit MAC address. This can be used to filter (block or forward) packets based on the originating device. MAC filtering policy and rules for the AR-5381u can be set according to the following procedure. The MAC Filtering Global Policy is defined as follows.

5.17 Interface Grouping Interface Grouping supports multiple ports to PVC and bridging groups. Each group performs as an independent network. To use this feature, you must create mapping groups with appropriate LAN and WAN interfaces using the Add button. The Remove button removes mapping groups, returning the ungrouped interfaces to the Default group. Only the default group has an IP interface. To add an Interface Group, click the Add button. The following screen will appear.
Automatically Add Clients With Following DHCP Vendor IDs: Add support to automatically map LAN interfaces to PVC's using DHCP vendor ID (option 60). The local DHCP server will decline and send the requests to a remote DHCP server by mapping the appropriate LAN interface. This will be turned on when Interface Grouping is enabled.
For example, imagine there are 4 PVCs (0/33, 0/36, 0/37, 0/38). VPI/VCI=0/33 is for PPPoE while the other PVCs are for IP set-top box (video). The LAN interfaces are ENET1, ENET2, ENET3, and ENET4. The Interface Grouping configuration will be: 1. Default: ENET1, ENET2, ENET3, and ENET4. 2. Video: nas_0_36, nas_0_37, and nas_0_38. The DHCP vendor ID is "Video". If the onboard DHCP server is running on "Default" and the remote DHCP server is running on PVC 0/36 (i.e. for set-top box use only).
