Chapter 1: Introduction
Introduction to your Router
The BiPAC 7800DX(L) is a dual-band wireless network device, it utilizes two wireless bands for
wireless communications, and offers maximum performance in setting up a network. Its built-in 4-
port Gigabit Ethernet Switch, supporting high-speed data transfer including a Gigabit WAN port for
Broadband connectivity. The Quality of Service (QoS) feature ensures a smooth net connection for
inbound and outbound data transmission with minimal traffic congestion. With the BiPAC
7800DX(L), you can create your own mobile hotspot for Wi-Fi access.
Dual-band
A Dual-band Router utilizes two different wireless bands that support connections on both 2.4GHz
and 5GHz simultaneously. The BiPAC 7800DX(L) is a dual-band router which transmits on two
frequency bands-2.4GHz and 5GHz simultaneously. The two wireless bands are fully independent.
One band can be used for downloading while the other is used for uploading; or one is used for
online gaming, video streaming and music downloading while the other takes care of accessing
email, file sharing and regular internet surfing. With an integrated 802.11 wireless access point, the
router can deliver up to 6 times the speed of an 802.11b/g wireless device. It supports a date rate of
up to 300 Mbps with each band and is also compatible with 802.11b/g devices in 2.4GHz and
802.11a in 5GHz.
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.
Jumbo frames supported
Jumbo frames are Ethernet frames with more than 1500 bytes (standard Ethernet frame) of payload.
Conventionally, jumbo frames can carry up to 9720 bytes of payload to enjoy a high-efficiency
communication in Gigabit Ethernet. Jumbo frames increase the frame size so that a certain large
amount of date can be transported with less effort, reducing CPU utilization and increasing
throughput by reducing the number of frames needing to be processed and reducing the total
overhead byte count of all frames sent.

2
3G/LTE
With 3G/LTE-based Internet connection (requires an additional 3G/LTE USB modem), user can
access internet through 3G/LTE, whether you are seated at your desk or taking a cross-country trip.
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.
Firmware Upgradeable
Device can be upgraded to the latest firmware through the WEB based GUI.

7 DSL Connect this port to the DSL network with the RJ-11 cable (telephone) provided.
8 Antenna The fixed dual-band antennas.

12
Cabling
One of the most common causes of problems 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 all 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.
Make sure you have a line filter with all devices (e.g. telephones, fax machines, analogue modems)
connected to the same telephone line 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.

13
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.
Any TCP/IP capable workstation can be used to communicate with or through this router. To
configure other types of workstations, please consult your manufacturer documentation.
