Appendix 1 Glossary

Channel:

An instance of medium use for the purpose of passing

protocol data units (PDUs) that may be used

simultaneously, in the same volume of space, with other

instances of medium use(on other channels) by other

instances of the same physical layer (PHY),with an

acceptably low frame error ratio(FER) due to mutual

interference.

SSID:

SSID(Service Set Identifier) is the network name

shared by all devices in a wireless network. Your

network’s SSID should be unique to your network and

identical for all devices within the network. It is

case-sensitive and must not exceed 20 characters (use

any of the characters on the keyboard).Make sure this

setting is the same for all devices in your wireless

network.

WEP:

Wired Equivalent Privacy (WEP) is the method for

secure wireless data transmission.

WEP adds data

encryption to every single packet transmitted in the

wireless network.

The 40bit and 64bit encryption are

the same because of out 64 bits, 40 bits are

Page 72 / 76

private.

Conversely, 104 and 128 bit are the

same.

WEP uses a common KEY to encode the

data.

Therefore, all devices on a wireless network must

use the same key and same type of encryption.

There

are 2 methods for entering the KEY; one is to enter a

16-bit HEX digit.

Using this method, users must enter

a 10-digit number (for 64-bit) or 26-digit number (for

128-bit) in the KEY field.

Users must select the same

key number for all devices.

The other method is to

enter a text and let the computer generate the WEP key

for you.

However, since each product use different

method for key generation, it might not work for

different products.

Therefore, it is NOT recommended

using.

WPA/WPA2 Encryption:

A security protocol for wireless networks that builds on

the basic foundations of WEP. It secures wireless data

transmission by using a key similar to WEP, but the

added strength of WPA is that the key changes

dynamically. The changing key makes it much more

difficult for a hacker to learn the key and gain access to

the network.WPA2 is the second generation of WPA

security and provides a stronger encryption mechanism

through Advanced Encryption Standard (AES), which is

a requirement for some government users.

Appendix 2 Questions and Answers

In this part some questions and problems shown during

the Router’s usage and installation will be given

suggesting answers. If your problems are not in the list,

please log into our website

www.tenda.cn

or send an

E-mail to

[email protected]

, and we will reply you in

the first time.

1. Can not login to the Web interface of the Router after

you enter the IP address in the address field?

Step 1: check the Router if it works well. Once the

device is powered on for a few seconds, the SYS

indicator on the panel will be turned on. If it is not,

please contact us.

Step 2: check the network cables if it is good and the

corresponding indicator is “Always ON”. Sometimes, the

indicator is “Always ON”, but it does not mean it gets

through.

Run “Ping” command and check if it can ping the

Router’s LAN IP address 192.168.0.1. If it is OK, please

make sure your browser does not access the Internet by

proxy server. If the ping fails, you can press the “RESET”

button for 7 seconds to restore to default settings. And

then repeat the ping operation. If it still does not work,

please contact us.

2.Forget the login password and can not enter the

setting page. What can I do?

Press the “RESET” button for 7 seconds to restore the

Router to default settings.

3.The computer connected with the Router shows IP

address conflict. What can I do?

Check if there are other DHCP servers in the LAN. If

there have, disable them. The default IP address of the

Router is 192.168.0.1 and please maker sure the

address is not occupied by other devices. If there are

two computers with the same IP addresses, please

modify one.

4.I can not use E-mail and access the Internet. What

can I do?

It happens in ADSL connection and Dynamic IP users.

And you need modify the default MTU value (1492).

Please in the “WAN Setting” modify the MTU value with

the recommended value as 1450 or 1400.

5.How can I configure and access the Internet via

Dynamic IP?

In Setup Wizard of the Web utility interface, select

“Dynamic IP” connection type and click “Save” to

activate it. As some ISPs bind the user computer’s MAC

address, you need to clone the Router’s WAN MAC

address to the bind21ing PC’s MAC address. Select

“MAC Address Clone” in “Advanced Setting” to input

your computer’s MAC address and click “Apply” to

activate it.

6.How to share my computer’s source with other users

in Internet?

If you want Internet users to access the internal server

via the Router such as e-mail server, Web, FTP, you can

configure the “Virtual Server” to come true.

Step 1: create your internal server, make sure the LAN

users can access these servers and know related service

port. For example, Web server’s port is 80; FTP is 21;

SMTP is 25 and POP3 is 110.

Step 2: in the Router’s web click “Virtual Server” and

select “Single Port Forwarding”.

Step 3: input the external service port given by the

Router, for example, 80.

Step 4: input the internal Web service port, for example,
