Introduction the Router
1.1 Introducing the Router
This Router is an economical ADSL2+ router ideal for Home and SOHO users to enjoy improved Wireless
Access Speed with a maximum operational speed of 150Mbps.It delivers the highest level of security with
higher speed and better coverage of wireless-n solutions.With an integrated 802.11n wireless access point, the
router enables faster wireless speeds of up to 150Mbps. The SOHO Firewall is integrated to provide protection
against hacker attacks while the Quality of Service prioritizes queues and traffic for applications such as music
downloads, online gaming, video streaming and file sharing.
Express Internet Access
Complying with worldwide ADSL standards, the Router supports downstream data transmission rates of up to
12/24 Mbps withADSL2/2+, 8 Mbps with ADSL, and performs at upstream rates of up to 1 Mbps. Moreover, the
Router includes Annex M technology that supports the latest ADSL2/2+ standard for higher upload speeds by
increasing the upstream operation rate to approximately 2.5Mbps (up to 3Mbps under ideal conditions). With
this technology, you can enjoy even higher-speed broadband multimedia applications such as interactive
gaming, video streaming and real-time audios that run faster and easier than ever.
Firewall Security and Smooth Traffic
With the built-in NAT default firewall, the advanced anti-hacker pattern-filtering protection features automatically
detect and block Denial of Service (DoS) attacks. In addition, packet filtering provides high-level security for
access control. Quality of Service control prioritizes the traffic and allows users to enjoy smooth traffic while
running applications such as IPTV, VoIP calls or interactive game through the Internet.
Easy Network Management
The Web-based user interface of the Router makes it extremely easy for users to install and manage the
network. The router supports both DHCP client and server, enabling system administrators to easily integrate
this router into existing network environments, as well as manage IP assignment without having to reconfigure
other stations.
IPv6 Ready - Pathway to the Future
The Router fully supportsIPv6 (Internet Protocol Version 6), launched as the current IPv4 range is filling up, and
IPv6 is gradually becoming the indispensable addressing system for savvy cloud computing users. Dual stack
means the router is capable of running IPv4 and IPv6 in parallel during the transition period. With IPv6 enabled
devices, three major transition mechanisms such as Dual-Stack, Dual-Stack Lite, and 6RD (IPv6 rapid
deployment) are supported to be adapted easily into service provider’s IPv4/IPv6 network.

2.5 Cabling
One of the most common causes of problems is bad cabling. Make sure that all connected devices are turned
on. On the front panel of the product is a bank of LEDs. Verify that the LAN Link and LEDs are lit. If they are not,
verify that you are using the proper cables.
Make sure that all other devices (e.g. telephones, fax machines, analogue modems) connected to the same
telephone line as your router have a line filter connected between them and the wall socket (unless you are
using a Central Splitter or Central Filter installed by a qualified and licensed electrician), and that all line filters
are correctly installed in a right way. If the line filter is not correctly installed and connected, it may cause
problems to your connection or may result in frequent disconnections.

Basic Installation
The router can be configured with your web browser. Aweb browser is included as a standard application in the
following operating systems: Windows XP/Vista/Win7/8, Linux, Mac OS, etc. The product provides an easy and
user-friendly interface for configuration.
3.1 Before Configuration
PCs must have an Ethernet interface installed properly and be connected to the router either directly or through
an external repeater hub, and have TCP/IP installed and configured to obtain an IP address through a DHCP
server or a fixed IP address that must be in the same subnet as the router. The default IP address of the router
is 192.168.1.254 and the subnet mask is 255.255.255.0 (i.e. any attached PC must be in the same subnet, and
have an IP address in the range of 192.168.1.1 to 192.168.1.253). The best and easiest way is to configure the
PC to get an IP address automatically from the router using DHCP. If you encounter any problems accessing the
router’s web interface it may also be advisable to uninstall any kind of software firewall on your PCs, as they
can cause problems accessing the 192.168.1.254 IP address of the router. Users should make their own
decisions on how to best protect their network.
Please follow the steps below for your PC’s network environment installation. First of all, please check your PC’s
network components. The TCP/IP protocol stack and Ethernet network adapter must be installed. If not, please
refer to your Windows-related or other operating system manuals.
Any TCP/IP capable workstation can be used to communicate with or
through the Router.To configure other types of workstations, please consult
the manufacturer’s documentation.
