27

two security protocols and security certification programs developed to
secure wireless computer networks. It is strongly suggested that you
use AES under 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, go to Appendix 2).

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.

Cipher Type: Select either AES (advanced encryption standard) or TKIP
(temporary key integrity protocol) type.
Security Key: Enter a security key，which must be between 8-63 ASCII
characters.
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.

28

Cipher Type: Select either AES (advanced encryption standard) or TKIP
(temporary key integrity protocol) type.
Security Key: Enter a security key，which must be between 8-63 ASCII
characters.

7.2 DHCP Settings

The Dynamic Host Configuration Protocol (DHCP) is an automatic
configuration protocol used on IP networks. If you enable the built-in
DHCP server on the 3G186R, it will 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 configuration. Just be sure to set your LAN 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 from the 3G186R.

IP Address: The device’s LAN IP address. You can change it from
default-192.168.2.1 to any other IP address of class C ONLY.
Subnet Mask: The device’s LAN subnet mask, 255.255.255.0 by

Mobile Wireless Modem

29

default.
DHCP Server: Check or uncheck the box to Enable or disable the
device’s DHCP server feature.
IP pool start address: Enter the starting IP address for the DHCP
server’s IP assignment.
IP pool end address: Enter the ending IP address for the DHCP
server’s IP assignment.
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.

7.3 Firewall

Firewall section includes IP-MAC Binding, MAC Filter, IP/Port Filter,
System Security, PIN Code Management and UPNP. Below presents you
detailed explanation of each feature mentioned herein.

7.3.1 IP-MAC Binding

This section allows you to assign IP addresses statically to your LAN
users and bind the assigned IP address with the LAN device’s MAC

Mobile Wireless Modem

30

address so that these LAN devices will always get the same IP addresses.
You can manually add an IP address and a MAC address and enable the
IP-MAC Binding feature, 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). Once a host is set to have its MAC address
bound to a specific IP address, it cannot use a different IP address
except the bound one to connect to the router for Internet access. Thus,
a host is prevented from escaping monitoring by changing its IP
address.

IP Address: Enter the IP address you want to statically assign and bind
to a LAN device.
MAC Address: Enter the MAC address of a LAN device to be bound to
the IP set above.

7.3.2 MAC Filter

To better manage the computers in LAN, you can use the MAC Address
Filter function to control LAN computer’s access to Internet.

Appendix 2 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 fo r w a rd by Qualc o m m , an Am e r i can wir e l e ss
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.

W-CDMA: W-CDMA (Wideband Code Division Multiple Access), also
known as CDMA Direct Spread, is found in 3G mobile

Mobile Wireless Modem

45

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 logical
connection over a multiplexed medium such as a radio channel. It is
used to transfer an information signal, such as a digital bit stream, 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. For example, if 3 American­standard 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. To let your
wireless network adapter roam among different APs, you must set all
Aps’ SSID to the same name.

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

Mobile Wireless Modem

46

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 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 3 Troubleshooting

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

1. Q: I entered the device’s LAN IP address in the web
browser but cannot access the utility. What should I do?

1） Verify physical connectivity by checking if corresponding port’s link
LED lights up. If not, try a different cable.
2） 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.

3) Click “Start" -- “Run”, enter “cmd” and then“ping 192.168.2.1”on
appearing CLI to diagnose whether your PC has connected to the device
or not. If ping succeeds, then check whether the Proxy Server feature is
enabled on your browser. If enabled, disable it immediately. In case that
ping fails, press and hold the "RESET" button on your device for over 7
seconds to restore factory default settings, and then run
“ping192.168.2.1” again.

4) Contact our technical support for help if the problem still exists after

Mobile Wireless Modem

48

you tried all the above.

2. Q: I forget the login password to my device, what
should I do?

In this case, you need to restore your device to factory default settings.
To do so, Press the hardware button RESET on your device for over 7
seconds and then release.

3. My computer shows an IP address conflict error after
having connected to the device. What should I do?

1) Check if there are other DHCP servers present in your LAN. If there
are other DHCP servers except your router, disable them immediately.

2) The default IP address of the device is 192.168.2.1; make sure this
address is not used by another pc or device. In case that two computers
or devices share the same IP addresses, change either to a different
address.

4. My computer can neither log in to the device nor
access internet, and there is a yellow triangle with an
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

Mobile Wireless Modem

49

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 address and fill in gateway and DNS,
otherwise you cannot access Internet.

5. How do I share resources with users on Internet
through the device?

To let Internet users access internal servers on your LAN such as e-mail
server, Web, FTP, via the device, use the “Virtual Server” feature. To do
so, follow 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.

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 or ICMP.

Step 7: Click “OK” to activate the settings.
