4RF Exposure Information (SAR)
This device meets the government’s requirements for exposure to radio waves. This
device is designed and manufactured not to exceed the emission limits for exposure to
radio frequency (RF) energy set by the Federal Communications Commission of the
U.S. Government.
The exposure standard for wireless device employs a unit of measurement known as the
Specific Absorption Rate, or SAR. The SAR limit set by the FCC is 1.6W/kg. *Tests for
SAR are conducted using standard operating positions accepted by the FCC with the
device transmitting at its highest certified power level in all tested frequency bands.
Although the SAR is determined at the highest certified power level, the actual SAR
level of the device while operating can be well below the maximum value. This is
because the device is designed to operate at multiple power levels so as to use only the
poser required to reach the network. In general, the closer you are to a wireless base
station antenna, the lower the power output.
SAR compliance has been established in the host product(s) (laptop computers), tested
at 5mm separation distance to the human body, and tested with USB slot configurations
including Horizontal-UP, Horizontal-Down, Vertical-Front, Vertical-Back. This device
can be used in host product(s) with substantially similar physical dimensions,
construction, and electrical and RF characteristics.
The highest SAR value, tested per FCC RF exposure guidelines for USB dongle, as
described in this user guide, is 0.67 W/kg. The FCC has granted an Equipment
Authorization for this device with all reported SAR levels evaluated as in compliance
with the FCC RF exposure guidelines. SAR information on this device is on file with
the FCC and can be found under the Display Grant section of www.fcc.gov/oet/ea/fccid
after searching on FCC ID: NDD9562881314.
Federal Communication Commission (FCC) Radiation Exposure
Statement
This EUT is compliance with SAR for general population/uncontrolled exposure limits
in ANSI/IEEE C95.1-1999 and had been tested in accordance with the measurement
methods and procedures specified in OET Bulletin 65 Supplement C. This equipment
should be installed and operated with minimum distance 0.5cm between the radiator &
your body.

read this troubleshooting first. Some problems can be solved by you within
very short time!
Scenario Solution
Router is not
responding to me
when I want to access
it by web browser
a. Please check the connection of power cord
and network cable of this router. All cords
and cables should be correctly and firmly
inserted to the router.
b. If all LEDs on this router are off, please
check the status of A/C power adapter, and
make sure it’s correctly powered.
c. You must use the same IP address section
which router uses.
d. Are you using MAC or IP address filter?
Try to connect the router by another
computer and see if it works; if not, please
restore your router to factory default
settings (pressing ‘reset’ button for over 10
seconds).
e. Set your computer to obtain an IP address
automatically (DHCP), and see if your
computer can get an IP address.

help.
g. If all above solutions don’t work, contact
the dealer of purchase for help.
Can’t get connected to
Internet
a. Go to ‘Status’ -> ‘Internet Connection’
menu, and check Internet connection status.
b. Please be patient, sometime Internet is just
that slow.
c. If you connect a computer to Internet
directly before, try to do that again, and
check if you can get connected to Internet
31
with your computer directly attached to the
device provided by your Internet service
provider.
d. Check PPPoE / L2TP / PPTP user ID and
password again.
e. Call your Internet service provide and check
if there’s something wrong with their
service.

4‐3Glossary
Default Gateway (Router): Every non-router IP device needs to configure a default
gateway’s IP address. When the device sends out an IP packet, if the destination is not
on the same network, the device has to send the packet to its default gateway, which will
then send it out towards the destination.
DHCP: Dynamic Host Configuration Protocol. This protocol automatically gives every
computer on your home network an IP address.
DNS Server IP Address: DNS stands for Domain Name System, which allows Internet
servers to have a domain name (such as www.Broadbandrouter.com) and one or more
IP addresses (such as 192.34.45.8). A DNS server keeps a database of Internet servers
and their respective domain names and IP addresses, so that when a domain name is
requested (as in typing "Broadbandrouter.com" into your Internet browser), the user is
sent to the proper IP address. The DNS server IP address used by the computers on your
home network is the location of the DNS server your ISP has assigned to you.
DSL Modem: DSL stands for Digital Subscriber Line. A DSL modem uses your
existing phone lines to transmit data at high speeds.
Ethernet: A standard for computer networks. Ethernet networks are connected by
special cables and hubs, and move data around at up to 10/100 million bits per second
(Mbps).
Idle Timeout: Idle Timeout is designed so that after there is no traffic to the Internet for
a pre-configured amount of time, the connection will automatically be disconnected.
IP Address and Network (Subnet) Mask: IP stands for Internet Protocol. An IP
address consists of a series of four numbers separated by periods, which identifies a
single, unique Internet computer host in an IP network. Example: 192.168.2.1. It
consists of 2 portions: the IP network address, and the host identifier.
The IP address is a 32-bit binary pattern, which can be represented as four cascaded
decimal numbers separated by “.”: aaa.aaa.aaa.aaa, where each “aaa” can be anything
from 000 to 255, or as four cascaded binary numbers separated by “.”:
bbbbbbbb.bbbbbbbb.bbbbbbbb.bbbbbbbb, where each “b” can either be 0 or 1.
A network mask is also a 32-bit binary pattern, and consists of consecutive leading
34
1’s followed by consecutive trailing 0’s, such as
11111111.11111111.11111111.00000000. Therefore sometimes a network mask can also
be described simply as “x” number of leading 1’s.
When both are represented side by side in their binary forms, all bits in the IP address
that correspond to 1’s in the network mask become part of the IP network address, and
the remaining bits correspond to the host ID.
For example, if the IP address for a device is, in its binary form,
11011001.10110000.10010000.00000111, and if its network mask is,
11111111.11111111.11110000.00000000
It means the device’s network address is
11011001.10110000.10010000.00000000, and its host ID is,
00000000.00000000.00000000.00000111. This is a convenient and efficient method for
routers to route IP packets to their destination.
ISP Gateway Address: (see ISP for definition). The ISP Gateway Address is an IP
address for the Internet router located at the ISP's office.
ISP: Internet Service Provider. An ISP is a business that provides connectivity to the
Internet for individuals and other businesses or organizations.
LAN: Local Area Network. A LAN is a group of computers and devices connected
together in a relatively small area (such as a house or an office). Your home network is
considered a LAN.
MAC Address: MAC stands for Media Access Control. A MAC address is the
hardware address of a device connected to a network. The MAC address is a unique
identifier for a device with an Ethernet interface. It is comprised of two parts: 3 bytes of
data that corresponds to the Manufacturer ID (unique for each manufacturer), plus 3
bytes that are often used as the product’s serial number.
NAT: Network Address Translation. This process allows all of the computers on your
home network to use one IP address. Using the broadband router’s NAT capability, you
can access the Internet from any computer on your home network without having to
purchase more IP addresses from your ISP.
Port: Network Clients (LAN PC) uses port numbers to distinguish one network
application/protocol over another. Below is a list of common applications and
protocol/port numbers:
Application Protocol Port Number
35
Telnet TCP 23
FTP TC P 21
SMTP TCP 25
POP3 TCP 110
H.323 TCP 1720
SNMP UCP 161
SNMP Trap UDP 162
HTTP TCP 80
PPTP TCP 1723
PC Anywhere TCP 5631
PC Anywhere UDP 5632
PPPoE: Point-to-Point Protocol over Ethernet. Point-to-Point Protocol is a secure data
transmission method originally created for dial-up connections; PPPoE is for Ethernet
connections. PPPoE relies on two widely accepted standards, Ethernet and the
Point-to-Point Protocol. It is a communications protocol for transmitting information
over Ethernet between different manufacturers
Protocol: A protocol is a set of rules for interaction agreed upon between multiple
parties so that when they interface with each other based on such a protocol, the
interpretation of their behavior is well defined and can be made objectively, without
confusion or misunderstanding.
Router: A router is an intelligent network device that forwards packets between
different networks based on network layer address information such as IP addresses.
Subnet Mask: A subnet mask, which may be a part of the TCP/IP information provided
by your ISP, is a set of four numbers (e.g. 255.255.255.0) configured like an IP address.
It is used to create IP address numbers used only within a particular network (as
opposed to valid IP address numbers recognized by the Internet, which must be
assigned by InterNIC).
TCP/IP, UDP: Transmission Control Protocol/Internet Protocol (TCP/IP) and
Unreliable Datagram Protocol (UDP). TCP/IP is the standard protocol for data
transmission over the Internet. Both TCP and UDP are transport layer protocol. TCP
performs proper error detection and error recovery, and thus is reliable. UDP on the
other hand is not reliable. They both run on top of the IP (Internet Protocol), a network
36
layer protocol.
WAN: Wide Area Network. A network that connects computers located in
geographically separate areas (e.g. different buildings, cities, countries). The Internet is
a wide area network.
Web-based management Graphical User Interface (GUI): Many devices support a
graphical user interface that is based on the web browser. This means the user can use
the familiar Netscape or Microsoft Internet Explorer to Control/configure or monitor the
device being managed.
