http://192.168.1.1.

The window will ask for

typing username and password.

Please type “admin/admin” on Username/Password for administration operation.

Now, the

Main Screen

will appear. Be aware that “Admin mode” will be displayed on the

bottom left side.

4.1 Internet Access

Quick Start Wizard

offers user an easy method to quick setup the connection mode for the

router. Moreover, if you want to adjust more settings for different WAN modes, please go to

group.

4.1.1 Basics of Internet Protocol (IP) Network

IP means Internet Protocol. Every device in an IP-based Network including routers, print

server, and host PCs, needs an IP address to identify its location on the network. To avoid

address conflicts, IP addresses are publicly registered with the Network Information Centre

(NIC). Having a unique IP address is mandatory for those devices participated in the public

network but not in the private TCP/IP local area networks (LANs), such as host PCs under the

management of a router since they do not need to be accessed by the public. Hence, the NIC

has reserved certain addresses that will never be registered publicly. These are known as

private

IP addresses, and are listed in the following ranges:

From 10.0.0.0 to 10.255.255.255

From 172.16.0.0 to 172.31.255.255

From 192.168.0.0 to 192.168.255.255

What are Public IP Address and Private IP Address

As the router plays a role to manage and further protect its LAN, it interconnects groups of

host PCs. Each of them has a private IP address assigned by the built-in DHCP server of the

Vigor router. The router itself will also use the default

private IP

address: 192.168.1.1 to

communicate with the local hosts. Meanwhile, Vigor router will communicate with other

network devices through a

public IP

address. When the data flow passing through, the

Network Address Translation (NAT) function of the router will dedicate to translate

public/private addresses, and the packets will be delivered to the correct host PC in the local

area network. Thus, all the host PCs can share a common Internet connection.

Get Your Public IP Address from ISP

In ADSL deployment, the PPP (Point to Point)-style authentication and authorization is

required for bridging customer premises equipment (CPE). Point to Point Protocol over

Ethernet (PPPoE) connects a network of hosts via an access device to a remote access

concentrator or aggregation concentrator. This implementation provides users with significant

ease of use. Meanwhile it provides access control, billing, and type of service according to

user requirement.

When a router begins to connect to your ISP, a serial of discovery process will occur to ask for

a connection. Then a session will be created. Your user ID and password is authenticated via

PAP

or

CHAP

with

RADIUS

authentication system. And your IP address, DNS server, and

other related information will usually be assigned by your ISP.

Network Connection by 3G USB Modem

For 3G mobile communication through Access Point is popular more and more, Vigor2920

adds the function of 3G network connection for such purpose. By connecting 3G USB Modem

to the USB port of Vigor2920, it can support HSDPA/UMTS/EDGE/GPRS/GSM and the

future 3G standard (HSUPA, etc). Vigor2920n with 3G USB Modem allows you to receive 3G

signals at any place such as your car or certain location holding outdoor activity and share the

bandwidth for using by more people. Users can use four LAN ports on the router to access

Internet. Also, they can access Internet via 802.11n wireless function of Vigor2920n, and

enjoy the powerful firewall, bandwidth management, VPN features of Vigor2920n series.

After connecting into the router, 3G USB Modem will be regarded as the second WAN port.

However, the original Ethernet WAN1 still can be used and Load-Balance can be done in the

router. Besides, 3G USB Modem also can be used as backup device. Therefore, when WAN1

is not available, the router will use 3.5G for supporting automatically. The supported 3G USB

4.1.2 General Setup

This section will introduce some general settings of Internet and explain the connection modes

for WAN1 and WAN2 in details.

This router supports dual WAN function. It allows users to access Internet and combine the

bandwidth of the dual WAN to speed up the transmission through the network. Each WAN

port (WAN1- through WAN port/WAN2- through LAN1 port) can connect to different ISPs,

Even if the ISPs use different technology to provide telecommunication service (such as DSL,

Cable modem, etc.). If any connection problem occurred on one of the ISP connections, all the

traffic will be guided and switched to the normal communication port for proper operation.

Please configure WAN1 and WAN2 settings.

This webpage allows you to set general setup for WAN1 and WAN respectively.

Note:

In default, WAN1 is enabled. WAN2 is optional.

Enable

Choose

Yes

to invoke the settings for this WAN interface.

Choose

No

to disable the settings for this WAN interface.

Display Name

Type the description for the WAN1/WAN2 interface.

Physical Mode

For WAN1, the physical connection is done and fixed through

Ethernet port; yet the physical connection for WAN2 is done

through an Ethernet port (P1) or USB port.
