6.2 Wireless Security

This section allows you to configure wireless encryption. The device
supports WPA-Personal, WPA2-Personal and mixed
WPA/WPA2-Personal. Wi-Fi Protected Access (WPA) and Wi-Fi
Protected Access II (WPA2) are two security protocols and security
certification programs developed to secure wireless computer
networks. It is strongly suggested that you use AES of
WPA-personal to encrypt your wireless network to block
unauthorized and undesired share of Internet connection. The
following introduces two commonest encryption methods (Wireless
network adapters need the required security key to connect to your
device, once you encrypt it. for configuration methods， please
refer to Appendix 2).

40

3G150B 150Mbps Portable 3G Wireless Router

6.2.1 WPA-PSK

The WPA protocol implements the majority of the IEEE 802.11i
standard. It enhances data encryption through the Temporal Key
Integrity Protocol (TKIP) which is a 128-bit per-packet key, meaning
that it dynamically generates a new key for each packet. WPA also
includes a

message integrity check feature to prevent data packets from
being hampered with. Only authorized network users can access the
wireless network.

¾ Security Mode: Select a proper mode that is also supported

by your wireless clients.

¾ Cipher Type: Select either AES (advanced encryption

standard) or TKIP (temporary key integrity protocol) type.

characters.

¾ Key Renewal Interval: Set a valid period for the security

key.

41

3G150B 150Mbps Portable 3G Wireless Router

6.2.2 WPA2-PSK

The later WPA2 protocol features compliance with the full IEEE

802.11i standard and uses Advanced Encryption Standard (AES) in
addition to TKIP encryption protocol to guarantee better security
than that provided by WEP or WPA.

¾ Security Mode: Select a proper mode that is also supported

by your wireless clients.

¾ Cipher Type: Select a cipher type from AES (advanced

encryption standard), TKIP (temporary key integrity protocol)
and TIKIP&AES.

Chapter 7 DHCP Server

DHCP server works only in 3G Router and wireless Router modes.

7.1 DHCP Server

The Dynamic Host Configuration Protocol (DHCP) is an automatic
configuration protocol used on IP networks. If you enable the
built-in DHCP server on your device , it wi ll automatically configure
the parameters of TCP/IP protocol for all your LAN computers
(including IP address, subnet mask, gateway and DNS etc),
eliminating the need for manual intervention. Be sure to set your
computers to be DHCP clients by setting their TCP/IP settings to
“Obtain an IP Address Automatically”. When you turn your
computers on, they will automatically load the proper TCP/IP
settings provided by the 3G150B.

44

3G150B 150Mbps Portable 3G Wireless Router

¾ DHCP Server: Check or uncheck the box to Enable or disable

the device’s DHCP server feature.

¾ IP pool start address: Enter the starting IP address for the

DHCP server’s IP assignment.

¾ IP pool end address: Enter the ending IP address for the

DHCP server’s IP assignment.

¾ Lease Time: The length of time for the IP address lease.

Configuring a proper lease time improves the efficiency for the

DHCP server to reclaim disused IP addresses.
For example：
If the lease time is an hour, then DHCP server will reclaim IP
addresses every hour.

7.2 DHCP Clients

DHCP client list displays the IP addresses, which clients obtained
from the device's DHCP server, MAC addresses, host names and
lease time. If you would like some devices on your network to
always have fixed IP addresses, you can manually add a DHCP
Reservation for each such device. You can manually add an IP
address and a MAC address and check the IP-MAC Binding option,
and then whenever a host with this MAC address connects to the
router, it will always get the same IP address (the one you just
added). According to the connected computer's MAC address, the
router checks relevant entries in its DHCP reservation list and
decides what IP address to assign to this host (an unused IP from

45

3G150B 150Mbps Portable 3G Wireless Router

DHCP IP address pool, or a reserved one): If it fails in finding a
reserved IP address bound to the PC with this MAC address in the
list, it will immediately assign an unused IP from its DHCP IP
address pool; and if such IP is found, it will be assigned to this host
so as to ensure that host with a DHCP reservation always get this
fixed reserved IP address. Once a host registers DHCP reservation
to have a fixed IP address bound to its MAC address, it can not use
a different IP address except this one to connect to the router for
Internet access. Thus, due to DHCP reservation, a host is prevented
from escaping monitoring by changing its IP address.

¾ IP Address: Enter the IP address which needs static binding.
¾ MAC Address: Enter the MAC address of the computer you

want to bind.
¾ Host name: It displays the name of the bound computer.
Lease Time: The remaining time for the corresponding IP address
lease.

Chapter 8 Virtual Server

The Virtual Server feature works in Wireless Router mode only.

8.1 Port Forwarding

Port forwarding feature allows you to open a single or a range of
WAN service ports and redirect all traffic received through these
ports to a LAN server with a designated IP address. It allows remote
computers, such as computers on the
specific computer or service within a private local area network
(LAN).

Internet, to connect to a

¾ Start/End Port: Enter the service port range provided by the

mapped host in internal network.

provides commonly used protocol ports. Select one from them

and then click the “Add to” button to automatically add

selected port to the Start Port-End Port fields of the

corresponding rule ID. You can also manually add the ports

which are not included in the “Well-Known Service Port”.
¾ Add to: Add a selected Well-Known Service Port to the Start

Port-End Port boxes of the rule you select.
For example:
You want to share some large files with your friends who are not i n
your LAN; howeve r it is no t co n v en ien t to t ransfer such large file s.
Then, you can set up your own PC as a FTP server and use the port
range forwarding feature to let your friends access these files.
Provided that the static IP address of the FTP server (Namely , your
PC) is 192.168.2.10 and you want your friends to access this FTP
server through default port 21 and TCP protocol, then you can
follow the steps below for configurations.

1. Enter 21 for both the start and end port in ID 1, or select "FTP"

48

3G150B 150Mbps Portable 3G Wireless Router

from “Well-Known Service Port” and port 21 will be added
automatically to ID 1.

2. Enter 192.168.2.10 for the "IP Address", select "TCP" and then
select "Enable'.

3. The configured parameters are shown in the screen below.

4. Click "OK".
Now, your friends only need to enter ftp://xxx.xxx.xxx.xxx:21 in
their browsers to access your FTP server. xxx.xxx.xxx.xxx is the
device's WAN IP address. For example, if it is 172.16.102.89, then
your friends only need to enter "ftp://172.16.102.89： 21" in
address fields of their respective browsers.

8.2 DMZ Settings

In some cases, we need to set a computer to be completely
exposed to extranet for implementation of a 2-way communication.

Appendix 3 Glossary

3G

3G refers to the 3rd Generation digital communication technology.
It provides application services such as multi-media, wide-area
wireless voice telephone, mobile Internet access, video calls,
mobile TV, e-business and etc, all in a mobile environment.
TD-SCDMA
TD-SCDMA (Time Division - Synchronous CDMA), found in UMTS
mobile telecommunications networks in China, adopts TDD, in
contrast to the FDD scheme used by W-CDMA. It can more easily
accommodate asymmetric traffic with different data rate
requirements on downlink and uplink than FDD schemes by
dynamically adjusting the number of timeslots used for downlink
and uplink. It also takes an advantage in spectrum allocation
flexibility, as it does not require paired spectrum for downlink and
uplink.

CDMA2000

CDMA2000 (also known as IMT Multi-Carrier (IMT-MC)) was put
forward by Qualcomm, an American wireless telecommunications
research and development company, as well as the largest fabless
chip supplier in the world. It is a family of 3G mobile technology
standards, transferring voice, data, and signaling data between
mobile phones and cell sites using CDMA channel access.

74

3G150B 150Mbps Portable 3G Wireless Router

W-CDMA

W-CDMA (Wideband Code Division Multiple Access), also known as
CDMA Direct Spread, is found in 3G mobile telecommunications
networks. It achieves higher speeds and supports more users than
most TDMA schemes through DS-CDMA channel access method
and the FDD duplexing method. Utilizing the same core network as
the 2G GSM networks deployed worldwide, it allows dual-mode
operation along with GSM/EDGE.

Channel

A communication channel, also known as channel, refers either to a
physical transmission medium such as a wire or to a
connection over a multiplexed medium such as a radio channel. It is
used to
from one or more transmitters to one or more receivers.
If there are several APs coexisting in the same area, it is
recommended that you configure a different channel for each AP to
minimize the interference between neighboring APs. F or example, if
3 American- standard APs (i.e. adopts channel 11) coexist in one
area, you can setup their channels respectively to 1, 6 and 11 to
avoid mutual interference.

SSID

Service set identifier (SSID) is used to identify a particular 802.11
wireless LAN. It is the name of a specific wireless network. Your
network’s SSID should be unique to your network. A wire less client
device needs to know a wireless network’s SSID in order to connect

transfer an information signal, such as a digital bit stream,

logical

75

3G150B 150Mbps Portable 3G Wireless Router

to it. A SSID can be up to 32 characters long.

WPA/WPA2

Wi-Fi Protected Access (WPA) and Wi-Fi Protected Access II (WPA2)
are two security protocols and security certification programs
developed to secure wireless computer networks.
The WPA protocol implements the majority of the IEEE802.11i
standard. Specifically, it enhances data encryption through the
Temporal Key Integrity Protocol (TKIP), which replaces WEP's
40-bit or 128-bit encryption key that must be manually entered on
wireless access points and devices and does not change. TKIP is a
128-bit per-packet key, meaning that it dynamically generates a
new key for each packet and thus prevents collisions. WPA also
includes a message integrity check feature to ensure that data
packets have not been tampered with. The later WPA2 indicates
compliance with the full IEEE 802.11i standard and uses Advanced
Encryption Standards (AES) encryption protocol that guarantees
better security.

WIFI

"Wi-Fi", short for Wireless Fidelity, is a trademark of the Wi-Fi
Alliance and the brand name for products using the IEEE 802.11
family of standards. It connects computers and other network
devices via wireless radio instead of cables.
AP
A wireless access point (AP) is a device that converts wired signal
into wireless signal, meaning that it allows wireless devices to

76

3G150B 150Mbps Portable 3G Wireless Router

connect to a wired network using Wi-Fi. It usually connects to a
router via a cable to relay data between the wireless and wired
devices on the network.

Appendix 4 Troubleshooting

This chapter provides solutions to problems that may occur during
the installation and operation of the device. Read the following
descriptions if you are having problems. If you can not find your
problem here, please go to our website www.tenda.cn or E-mail to
[e-mail] for help.

1. Why can’t I access the web-based configuration utility?

Please first verify physical connectivity by checking for solid link
lights on the device. If you do not get a solid link light, try using a
different cable.
Then verify the device’s mode. In wireless router mode, the
device’s LAN/WAN port functions as a WAN port only, so you can
access its web-based interface via wireless connection only. In
wireless access point (AP) mode, you must specify an IP address for
your computer (between 192.168.2.2~192.168.2.254) to access
its web-based interface . Please click “Start" -- " Run "to enter “ping

192.168.2.1”to diagnose whether the device is connected or not. If
ping succeeds, then check whether you have enabled the Proxy
Server feature on your browser . If enabled， you need to disable it.
If ping fails, press and hold the "RESET" button on the device for
over 7 seconds to restore the factory defaults, and run
“ping192.168.2.1” again. And if you still can not access, please
contact our technical support.

2. What can I do if I forgot my password for accessing the
web utility?

In this case, you have to reset your device. T o do so, press and hold
the “RESET” button for over 7 seconds. Release the button and the
device will go through its reboot process. The default password is
“admin”.

3. Why does my computer show an IP address conflict after
connected with the device?

Check if there are other DHCP servers in the LAN. If there are,
please disable them.
The default IP address of the device is 192.168.2.1, please make
sure the address is not used by another pc or device. If there are
two computers or devices with the same IP address, please modify
one.

4. My computer can neither log in to the device nor access
internet, and there is a yellow triangle with a exclamation
mark shown in the network adapter icon on the right bottom
corner of my computer desktop; How am I supposed to deal
with it?

This problem occurs because your network card has not been
assigned with an IP address. If your computer is set to obtain an IP
address automatically, please ensure that the router's DHCP
function is enabled. DHCP can automatically assign an IP address to
your computer. If there is no DHCP, please set a static IP addre ss
and fill in gateway and DNS, otherwise you can not access Internet.

5. Why can’t I access Internet or send and receive emails
through my router?

This may happen to ADSL and Dynamic IP users. First, you need to
check whether the RJ-45 port, which serves as a WAN port, is
correctly connected; if there is no problem with the physical
connectivity, then, you need to modify the default MTU value
(1492). Please replace the default MTU value with the
recommended value of 1450 or 1400 in the “WAN Setting”
interface.

6. How can I access Internet using Dynamic IP access
mode?

In Setup Wizard of t he We b-based utility int erface, select “Dyn amic
IP” connection type and click “Save” to activate it.

7. How do I share resources on my computer with users on
Internet through the device?

To let Internet users access i nternal servers on your LAN such as
e-mail server, Web, FTP, via the device, use the “Virtual Server”
feature. To do so, follows the steps below:
Step 1: Create your internal server, make sure the LAN users can
access these servers and you need to know related service ports,
for example, Web server’s port is 80; FTP is 21; SMTP is 25 and
POP3 is 110.
Step 2: Click “Virtual Server” and select “Port Forwarding” on the
Router’s web interface.

80

Step 3: Input the external service port, for example, 80.
Step 4: Input the internal Web service port, for example, 80.
Step 5: Input the internal server’s IP address. For example, if your

Web server’s IP address is 192.168. 2.10, please input it.
Step 6: Select a communication protocol used by your internal host:
TCP, UDP o r ICMP.
Step 7: Click “OK” to activate the settings.
