Your gateway at a glance The AT-AR236E ADSL Ethernet & USB Combo Router has several ports and LEDs. Let’s take a look at them. Ports and buttons Reset and Restore to Factory Defaults: The restore to factory defaults feature will set the ADSL Router back to its factory default configuration.
Installing your ADSL Router 1. Locate an optimum location for the ADSL Router. 2. For connections to the Ethernet and DSL interfaces, please refer to the easy start guide. 3. Connect the AC Power Adapter. Depending upon the type of network, you may want to put the power supply on an uninterruptible supply.
Setting up your ADSL Router This section will guide you through your ADSL Router’s configuration. The ADSL Router is shipped with a standard PPP configuration. Log into your ADSL Router To configure your ADSL Router, open your web browser. You may get an error message at this point;...
Quick Start The first screen (Figure 2) that appears (after the log in screen) is the Quick Start screen. Depending on the country that you reside in, some profiles had been preset for the VPI/VCI and type of encapsulation. For example, if you reside in New Zealand, click on the button for New Zealand and then click Next.
Setup (for advance user) From this screen the user can setup the ADSL Router (configure the LAN and WAN connection(s), configure the advanced configuration options within the ADSL Router (security, routing, and filtering), access tools that are helpful for debug purposes, obtain the status of the modem, and view the extensive online help.
Configuring the WAN Before the gateway will pass any data between the LAN interface(s) and the WAN interface, the WAN side of the modem must be configured. Depending upon your DSL service provider or your ISP, you will need some (or all) of the information outlined below before you can properly configure the WAN: Your DSL line VPI and VCI Your DSL encapsulation type and multiplexing...

4.4.1.3 PPPoE Connection Setup PPPoE is also known as RFC 2516. It is a method of encapsulating PPP packets over Ethernet. PPP or Point-to-Point protocol is a method of establishing a network connection/session between network hosts. It usually provides a mechanism of authenticating users. To configure the gateway for PPPoE, click on Setup and then click on default PPPoE connection setup is displayed.

Configuring the LAN By default, your ADSL Router has DHCP server (LAN side) enabled. If you already have a DHCP server running on your network, you must disable one of the two DHCP servers; if you plug a second DHCP server into the network, you will experience network errors and the network will not function normally.
In addition to the DHCP server feature, the ADSL Router supports the DHCP relay function. When the ADSL Router is configured as DHCP server, it assigns the IP addresses to the LAN clients. When the ADSL Router is configured as DHCP relay, it is responsible for forwarding the requests and responses negotiating between the DHCP clients and the server.
The hostname can be any alphanumeric word that does not contain spaces. The domain name is used in conjunction with the host name to uniquely identify the gateway. To access the ADSL Router’s web pages the user can type 192.168.1.1 (the default IP address) or type mygateway.ar7.
Advanced (for advance user only) The ADSL Router supports a host of advanced features. For basic ADSL Router functionality, the user does not need to utilize these advanced features. The features help with routing, security, port configuration, and plug and play capability. 4.6.1 UPnP UPnP NAT and Firewall Traversal allow traffic to pass-thru the ADSL Router for applications using the UPnP protocol.
4.6.2 Port Forwarding Using the Port Forwarding page, you can provide local services (for example web hosting) for people on the Internet or play Internet games. When users send this type of request to your network via the Internet, the ADSL Router will forward those requests to the appropriate PC. Port forwarding can be used with DHCP assigned addresses but remember that a DHCP address is dynamic (not static).
4.6.3 Advanced Security In the presence of the firewall, anonymous Internet traffic is blocked. Using the advanced security features, you can redirect this traffic to a dedicated computer on your local network (DMZ) or open the access from the Internet to the ADSL Router's management ports (web, telnet). To enable any of the advanced security features, click Advanced and configure the option under Firewall.
4.6.3.2 Enable Web from WAN Enabling the Web from WAN on your local network allows Web requests that come from the Internet to be re-routed to a Web Server that is on a different subnet. This is different that the Web server rule that is configurable via the port-forwarding page.
4.6.6 MAC Address Filters The MAC filtering mechanism provides a way for the users to define rules to allow/deny frames through the bridge based on source MAC address, destination MAC address and/or frame type. When bridge filtering is enabled, each frame is examined against the defined filter rules sequentially, and when a matched is determined, the appropriate filtering action (determined by the access type selected ...
Note: The MAC filter table contains 3 hidden rules. These rules are entered automatically by the system to ensure the user does not "lock" them out of the system. The first rule allows any and all ARP frames through the system. The second rule allows all IPv4 frames with the destination MAC address of the bridge to go through.
The apply button will temporarily save this connection. To make the change permanent you need to click on Save Settings (at the side of the page). At the system commands page, click on Save All. 4.6.8 Static Routing If the ADSL Router is connected to more than one network, you may need to set up a static route between them.
4.6.9 Dynamic Routing Dynamic Routing allows the ADSL Router to automatically adjust to physical changes in the network. The ADSL Router, using the RIP protocol, determines the network packets’ route based on the fewest number of hops between the source and the destination. The RIP protocol regularly broadcasts routing information to other ADSL Routers on the network.
Tools The ADSL Router supports a host of tools that will allow you to customize and debug your ADSL Router. 4.7.1 System Commands To make the changes permanent you need to click on Tools (at the top of the page) and select System Commands.
4.7.3 Update Firmware You can remotely upgrade the ADSL Router’s firmware, clicking on Update Firmware under the Tools page. This will bring up the screen shown in Figure 19. The upgrade file shall be in *.img format. To upgrade the firmware, click browse, find the firmware file to download. Make sure this is the correct file.
4.7.4 Ping Test Once you have your ADSL Router configured, it is a good idea to make sure you can ping the network. You can get to the Ping page under the Tools title, by clicking on Ping Test. Type the target address that you want to ping.
Status The Status section allows you to view the Status/Statistics of different connections and interfaces 4.8.1 Network Statistics Select to view the Statistics of different interfaces - Ethernet/USB/DSL. 4.8.2 Connection Status Select to view the Status of different connections. 4.8.3 DHCP Clients Select to view the list of DHCP clients.
4.8.6 System Log You can display the ADSL Router’s log by going under the Status title, click System log. From here you can view all logged information. Depending upon the severity level, this logged info will generate log reports to a remote host (if remote logging is enabled). - 33 -...
Appendix A: Troubleshooting Below is a list of commonly asked questions. Before calling technical support, please look through these issues to see if they help to solve your problem. The ADSL Router is not functional Check to see that the power LED is green and than the network cables are installed correctly.
The DSL Link LED continues to blink but does not go solid 1. This means that the DSL line is trying to train but for some reason it cannot establish a valid connection. The main cause of this is that you are too far away from the central office.
ADSL Router terms What is a firewall? A firewall is protection between the Internet and your local network. It acts similarly to the firewall in your car, protecting the interior of the car from the engine. Your car's firewall has very small opening that allow desired connections from the engine into the cabin (gas pedal connection, etc), but if something happens to your engine, you are protected.
