Chapter 1: Introduction
Introduction to your Router
The BiPAC 7820NZ, triple-WAN 3G/LTE/ADSL2+ firewall router is integrated with the 802.11n
Wireless Access Point and 4-port switch. It is a cutting-edge networking product for SOHO and
office users. Uniquely, the router allows users to directly insert 3G/4G LTE SIM card into its built-in
SIM slots instead of requiring external USB modems. This design will avoid compatibility issues of
many different 3G/LTE USB modems. With the increasing popularity of the 3G/4G LTE standard,
communication via the BiPAC 7820NZ is becoming more convenient and widely available -
enabling users to use a 3G/4G LTE, UMTS, EDGE, GPRS, or GSM Internet connection, making
downstream rates of up to 100Mbps possible. Users can watch movies, download music or access
e-mail wherever a 3G/4G LTE connection is available.
3G/4G LTE Mobility and Always-on Connectivity
The BiPAC 7820NZ router allows you to insert 3G/4G LTE SIM card to its built-in SIM slots,
enabling you to use a 3G/4G LTE Internet connection, which makes downstream rates of up to
100Mbps*3 possible. With the increasing popularity of the 3G/4G LTE standard, communication via
the BiPAC 7820NZ is becoming more convenient and widely available - allowing you to watch
movies, download music on the road, or access e-mail no matter where you are. You can even
share your Internet connection with others, no matter if you're in a meeting, or speeding across the
country on a train. The auto fail-over feature ensures optimum connectivity and minimum
interruption by quickly and smoothly connecting to a 3G/4G LTE network in the event that you
ADSL/Fibre/Cable line fails. The BiPAC 7820NZ will then automatically reconnect to the
ADSL/Fibre/Cable connection when it is restored, reducing connection costs. These features are
perfect for office situations when a constant and smooth WAN connection is critical.
Optimal wireless performance
With an integrated 802.11n Wireless Access Point, the router delivers up to 6 times the speed of an
802.11a/b/g network device. It supports a data rate of up to 300Mbps and is also compatible with
802.11a/b/g equipment. The Wireless Protected Access (WPA-PSK/WPA2-PSK) and Wireless
Encryption Protocol (WEP) features enhance the level of transmission security and access control
over wireless LAN. The router also supports the Wi-Fi Protected Setup (WPS) standard, allowing
users to establish a secure wireless network by simply pushing a button. If your network requires
wider coverage, the built-in Wireless Distribution System (WDS) repeater function allows you to
expand your wireless network without the need for any external wires or cables.
Secure VPN Connections
The BiPAC 7820NZ supports all currently popular secure VPNs, including embedded IPSec VPN,
PPTP, L2TP, OpenVPN, GRE, which satisfies different users’ needs, allowing users to establish
encrypted private connections over the Internet with your optimum VPN options. You can access
your corporate Intranet and transmit sensitive data between branch offices and remote sites
anytime; even when you are out of office, thus enhancing productivity.

2
Smooth, Responsive Net Connection
Quality of Service (QoS) gives user full control over outgoing data traffic. Priority can be assigned
by the router to ensure that important transmissions like gaming packets, or IPTV/streaming content
passes through the router at lightning speed, even when there is heavy Internet traffic. The 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.
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.
The BiPAC 7820NZ fully supports IPv6 (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 Billion 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
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.

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.

/ 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.
