Chapter 1: Introduction
Introduction to your Router
Thank you for purchasing BiPAC 7800NEXL router, an all-in-one ADSL2+ Router with wireless-N
technology. The BiPAC 7800NEXL is an ADSL2+ Router that offers users affordable expanded
wireless coverage and speedy Internet connection. By supporting Internet Protocol, IPv6, this All-in-
One Router allows users to make internet connections between existing IPv4 networks and future
IPv6 network upgrades when greater security, high quality QoS and larger addressing are required.
With an integrated 802.11n Access Point, the BiPAC 7800NEXL can automatically adopt an optimal
connection to deliver smooth, constant signal reception even if obstacles are present. Robust
Firewall security is featured to protect Internet access against hacker attacks. The Quality of
Service and VLAN enables intelligent steaming for HD video or multiple applications such as music
downloads, online gaming, video streaming and file sharing simultaneously.
Optimal Wireless Speeds and Coverage
With an integrated 802.11n Wireless Access Point, this router supports a data rates up to 300Mbps
and delivers up to 6 times the speed and 3 times the wireless coverage of an 802.11b/g network
device. If the network requires wider coverage, the built-in Wireless Distribution System (WDS)
repeater function allows users to expand the wireless network without the need for any external
wires or cables.
Jitter-free, Reliable Net Traffic
Quality of Service (QoS) gives full control over outgoing data traffic. Priority can be assigned by the
router to ensure that important transmissions like gaming packets, VoIP calls or IPTV / streaming
content passes through the router at lightning speed, even when there is heavy Internet traffic. The
transfer speed of different types of outgoing data passing through the router is also controlled to
ensure that users do not saturate bandwidth with their browsing activities. The VLAN support is also
capable of establishing reliable high-speed transmissions for wide bandwidth applications such as
IPTV, VOD, or online gaming without consuming bandwidth.
High-speed Internet Access
The BiPAC 7800NEXL is compliant with worldwide ADSL standards, and supports download rates
of up to 12 / 24Mbps using ADSL2 / 2+, 8Mbps using ADSL and an upload rate of up to 1Mbps.
The integrated Annex M standard supports ADSL2 / 2+ for higher uploads by doubling the upload
data rate. The 4-port Ethernet Switch incorporated into the BiPAC 7800NEXL enables users to
connect to multiple computers or wired-Ethernet devices easily and enjoy blistering LAN
transmission for multimedia applications such as interactive gaming, IPTV video streaming and
real-time audio.
Simple Setup, Ease of Management
Easy Sign-On (EZSO), WPS push button and Auto-scan ADSL settings allow users to manage the
device functions effortlessly! The user-friendly, web-based user interface makes installing and
managing the BiPAC 7800NEXL extremely easy. With support for both DHCP client and server,
system administrators can manage IP assignment without having to reconfigure other stations and
fitting the router into existing network environments.

IPv6 supported
Internet Protocol version 6 (IPv6) is a version of the Internet Protocol that is designed to succeed
IPv4. IPv6 has a vastly larger address space than IPv4. This results from the use of a 128-bit
address, whereas IPv4 uses only 32 bits. The new address space thus supports 2128 (about
3.4×1038) addresses. This expansion provides flexibility in allocating addresses and routing traffic
and eliminates the primary need for network address translation (NAT), which gained widespread
deployment as an effort to alleviate IPv4 address exhaustion.
IPv6 also implements new features that simplify aspects of address assignment (stateless address
autoconfiguration) and network renumbering (prefix and router announcements) when changing
Internet connectivity providers. The IPv6 subnet size has been standardized by fixing the size of the
host identifier portion of an address to 64 bits to facilitate an automatic mechanism for forming the
host identifier from Link Layer media addressing information (MAC address).
Network security is integrated into the design of the IPv6 architecture. Internet Protocol Security
(IPsec) was originally developed for IPv6, but found widespread optional deployment first in IPv4
(into which it was back-engineered). The IPv6 specifications mandate IPsec implementation as a
fundamental interoperability requirement.
VLAN MUX
A Virtual LAN, commonly known as a VLAN, is a group of hosts with the common set of requirements
that communicate as if they were attached to the same broadcast domain, regardless of the physical
location. A VLAN has the same attributes as a physical LAN, but it allows for end stations to be
grouped together even if they are not located on the same network switch.
The most commonly used Virtual LAN is defined by 802.1Q tagging protocol, which expended the
original Ethernet frame header to include VLAN ID (tag) and priority bits. With the support of
network equipments, multiple virtual networks can coexist over the same physical network. Ethernet
frames are used to transfer data over ADSL line when bridging, MER or PPPoE mode is used.
While the DSL connection we usually configured is to use a PVC match a single service, PPPoE
PPPoA, bridging, etc. With the VLAN tag, we can make virtual interfaces to create multiple separate
WAN connections within the same PVC. It allows multiple services over the same PVC. The VLAN
Mux feature is designed for this purpose. For example, you have an ATM interface, PVC with
VPI/VCI 8/35, you can set the PPPoE, IPoE, and Bridge connection via the PVC without
respectively assigning the three services to three different PVCs.
Virtual AP
A “Virtual Access Point” is a logical entity that exists within a physical Access Point (AP). When a
single physical AP supports multiple “Virtual APs”, each Virtual AP appears to stations (STAs) to be
an independent physical AP, even though only a single physical AP is present. For example,
multiple Virtual APs might exist within a single physical AP, each advertising a distinct SSID and
capability set. Alternatively, multiple Virtual APs might advertise the same SSID but a different
capability set – allowing access to be provided via Web Portal, WEP, and WPA simultaneously.
Where APs are shared by multiple providers, Virtual APs provide each provider with separate
authentication and accounting data for their users, as well as diagnostic information, without
sharing sensitive management traffic or data between providers. You can enable the virtual AP.
Web Based GUI
It supports web based GUI for configuration and management. It is user-friendly and comes with
online help. It also supports remote management capability for remote users to configure and
manage this product.

12
Cabling
One of the most common causes of problem is bad cabling or ADSL line(s). Make sure that all
connected devices are turned on. On the front panel of your router is a bank of LEDs. Verify that the
LAN Link and ADSL line LEDs are lit. If they are not, verify if you are using the proper cables. If the
error persists, you may have a hardware problem. In this case you should contact technical support.
Ensure that all other devices connected to the same telephone line as your router (e.g. telephones,
fax machines, analogue modems) 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 ensure that all line filters are correctly installed and the right way around. Missing
line filters or line filters installed the wrong way around can cause problems with your ADSL
connection, including causing frequent disconnections. If you have a back-to-base alarm system you
should contact your security provider for a technician to make any necessary changes.

Chapter 3: Basic Installation
The router can be configured through your web browser. A web browser is included as a standard
application in the following operating systems: Linux, Mac OS, Windows 7 / 98 / NT / 2000 / XP / Me
/ Vista, etc. The product provides an easy and user-friendly interface for configuration.
Please check your PC 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.
There are ways to connect the router, either through an external repeater hub or connect directly
to your PCs. However, make sure that your PCs have an Ethernet interface installed properly prior
to connecting the router device. You ought to configure your PCs 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 problem accessing the router web interface it is advisable to
uninstall your firewall program on your PCs, as they can cause problems accessing the IP address
of the router. Users should make their own decisions on what is best to protect their network.
Please follow the following steps to configure your PC network environment.
