1. Product Overview
1.1 Introduction
G2Wifi II, a 3G/3.5G WiFi Router, is enhanced the optional functions of VoIP and/or voice wireless
local loop (WLL). Through these enhancements of this device, it will allow an analog phone to be
used as an IP phone with theATA board and/or as a cell phone with the VOICE board.
Besides, with the optional built-in or external USB modem, it has failover function using the dial-up
modem. Not only can it be used as a regular router to connect to ADSL / Cable modem but also as a
PPP router using the dial-up modem to connect to the ISP. The dial-up modem could be PSTN V.90,
GPRS, CDMA, EVDO, 3G / 3.5G HSDPA and Edge modem, etc.
The router will use WAN as the first priority and the dial-up modem as the backup. Once the WAN
port is active, it will switch to WAN and disconnect the dial-up connection. The router will
automatically dial to ISP if WAN is not active and there is data to be transmitted.
The followings are other G2wifi II models we offer for your options. Please purchase G2wifi II router
depending on your needs:

3. Web-Based Management
This chapter instructs you how to configure and manage the G2wifi II through the web user interface
it supports. With this facility, you can easily access and monitor through any one LAN port of the
G2wifi II router.
After G2wifi II has been connected to your PC via RJ45 network cable, type http://192.168.8.1 in IE
browser, it will show the following screen and ask you to input the user name and password in order
to login and access authentication. The default user name is “admin” or “user”, and the password
is blank. With the former user name to login, the user is able to fully access and configure the system.
As to the latter, the user merely owns the right to read the system. For the first time to use, please
enter the default user name and keep the password blank, then click the Log In button. The setup
page for G2wifi II will be displayed once the login process is successful.

3.1. Basic
3.1.1 Wizard
Internet Connection Setup Wizard:
This wizard guides you through the following basic router setup steps:
Set your Password
Select your Time Zone
Configure your Internet Connection
3.1.2 WAN
The WAN (Wide Area Network) section is where you configure your Internet connection type.
There are several connection types to choose from: Static IP, DHCP, PPPoE, PPTP, L2TP, and
BigPond. If you are unsure of your connection method, please contact your Internet Service
Provider. Note: If using the PPPoE option, you will need to ensure that any PPPoE client software
on your computers is removed or disabled.
3.1.2.1 Static WAN Mode
Used when your ISP provides you a set IP address that does not change. The IP information is
manually entered in your IP configuration settings. You must enter the IP address, Subnet Mask,
Gateway, Primary DNS Server, and Secondary DNS Server. Your ISP provides you with all of this
information.
3.1.2.2 DHCP WAN Mode
A method of connection where the ISP assigns your IP address when your router requests one from
the ISP's server. Some ISP's require you to make some settings on your side before your router can
connect to the Internet.
Host Name: Some ISP's may check your computer's Host Name. The Host Name identifies
your system to the ISP's server. This way they know your computer is eligible to receive an IP
address. In other words, they know that you are paying for their service.

19
Use Unicasting: This option is normally turned off, and should remain off as long as the
WAN-side DHCP server correctly provides an IP address to the router. However, if the router
cannot obtain an IP address from the DHCP server, the DHCP server may be one that works
better with unicast responses. In this case, turn the unicasting option on, and observe whether
the router can obtain an IP address. In this mode, the router accepts unicast responses from
the DHCP server instead of broadcast responses.
Enable BigPond: Check this option to connect to the Internet through Telstra BigPond Cable
Broadband in Australia. Telstra BigPond provides the values for BigPond Server, BigPond
User Id, and BigPond Password.

3.1.2.3 PPPoE
Select this option if your ISP requires you to use a PPPoE (Point to Point Protocol over Ethernet)
connection. DSL providers typically use this option. This method of connection requires you
to enter a Username and Password (provided by your Internet Service Provider) to gain
access to the Internet.
Dynamic IP: If your ISP has assigned a fixed IP address, select this option. The ISP provides
the value for the IP Address.
Static IP: If the ISP's servers assign the router's IP addressing upon establishing a
connection, select this option.
Service Name: Some ISP's may require that you enter a Service Name. Only enter a Service
Name if your ISP requires one.
Reconnect Mode: Typically connections are not always on. The 3Jtech router allows you to
set the reconnection mode. The settings are:
Always on: A connection to the Internet is always maintained.
On demand: A connection to the Internet is made as needed.
Manual: You have to open up the web-based management interface and click the
Connect button manually any time that you wish to connect to the
Internet.
Maximum Idle Time: Time interval the machine can be idle before the PPPoE connection is
disconnected. The Maximum Idle Time value is only used for the "On demand" connection
mode.
