Chapter 9 Routing Settings 
9.1 Routing Table 
This page shows the router’s core routing table. 
 The  main  duty  for  a  router  is  to  look  for  a  best  path  for  every  data packet,  and  transfer 
this data packet to a destination station. In order to fulfill this function, many transferring 
paths, i.e. routing table, are saved in the router, for choosing when needed. 
 
9.2 Static Routing 
This screen is used to set the router’s static routing. 
A static route is a pre-determined pathway that network information must travel to reach 
a specific host or network. 
  Destination network IP address: The destination host or IP segment you visit. 
 Subnet mask: Enter the subnet mask, generally it is 255.255.255.0 
 Gateway: The entry IP address of the next router. 
 
NOTE:

1. The gateway must be at the same net segment with the router’s LAN IP. 
2. If the  destination  IP  address  is  one  host’  address,  then  the  subnet  mask  must  be 
255.255.255.255. 
3. If the  destination  IP  address  is  an  IP  segment,  then  it  must  match  with  the  subnet 
mask.  For  example,  if  the  destination  IP  is  10.0.0.0  then  the  subnet  mask  must  be 
255.0.0.0

Chapter 10 System Tools 
10.1 Time Settings 
This section is to configure the router’s system time. You can set it manually or obtain the 
GMT time from the Internet. 
  Time zone: Select  the time  zone where  you  are  operating  the  Router from  the 
drop-down list. 
 Customized time: Enter the time you wish to configure. 
NOTE: 
When  the  Router  is  powered  off,  the time settings will  be  lost. The  router  will  obtain  the 
GMT time automatically when you next time access the Internet. Only when you connect 
to  the  Internet  and  obtain  the GMT time  or  set  the  time  on  this screen,  can the  time 
settings in other functions (e.g. security settings) take effect. 
 
10.2 DDNS 
The  DDNS  (Dynamic  Domain  Name  System)  is  supported  in  this  Router.  It  is used to 
assign a fixed host and domain name to a dynamic Internet IP address. Every time you 
access  the  Internet,  the dynamic  domain  name  software  installed on  your  host  will  tell 
the  ISP’S  host  server  its  dynamic  IP  address  by  sending  messages.  And  the  server 
software is  responsible  for  providing  DNS  service  and  implementing dynamic  domain 
name resolution.

  Main features:  
1.  Mostly,  your ISP provides a dynamic  IP  address and  the DDNS  is  used  to 
capture  the  changeable  IP  address and match to the  fixed  domain.  Then  users 
can have access to the Internet to communicate with others outside the network.  
2. DDNS can help you to establish a virtual host in your home or company. 
 DDNS: Click the radio button to enable or disable the DDNS service. 
 Service provider: Select  one  from  the  drop-down list and click “Sign  up”  for 
registration.  
 Username: Enter the username that you use to register from the DDNS provider  
 Password: Enter the password that you use to register from the DDNS provider  
 Domain name: Enter the effective registered domain name 
For example: 
Establish  a  Web  server in  the  local  host  192.168.0.10 and  register  in  3322.org  as 
follows: 
Username Tenda 
Password 123456 
Domain Name tenda.3322.org 
After  mapping the  port in  the  virtual  server, and setting  account  information  in  DDNS 
server, you  can  then  access  the  web  page by entering http://tenda.3322.org in  the 
address field. 
 
10.3 Backup/Restore  
On this screen, you can back up the router’s current settings or restore previous settings.

Click the “Restore” button to restore previous settings. 
 
 
10.4 Restore to Factory Default  
This screen allows you to restore all settings to the factory default values.  
  Restore: Click this button to restore to default settings.  
 Factory default settings: 
Password: NULL(the default password displays as null) 
IP address: 192.168.0.1 
Subnet mask: 255.255.255.0 
NOTE:  
After  restoring  to  default  settings,  please  restart  the router  to  make  the default  settings 
effective. 
 
10.5 Upgrade  
By  upgrading  the  router’s software,  you’ll  get better software version  and  appreciated 
routing function. Before upgrading, download the Router’s software upgrade file from our 
website, www.tenda.cn.

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. 
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. 
802,1x authentication  
Static  WEP  key  is  difficult  to  manage  for  when  you  change  the  key,  you  will  have  to 
inform  all  others, and  if the key  is  disclosed  in  one  of the places, the key  can  no  longer 
provide security. Besides, there’s severe security loophole about static WEP encryption. 
The WEP key can be decrypted after one person receives a specific amount of data via 
wireless intercepting. 802,1x is initially used for wired Ethernet authentication access to 
prevent illegal users from accessing the network. Later, it is found that 802.1x can better 
solve  the  wireless  network  security  problem.  EAP-TLS  of  the  802.1x  successfully 
achieves  the  two-way  authentication  between  users  and  networks,  i.e.  can  prevent 
illegal users from accessing the network and can also prevent users from accessing the 
illegal  AP.  802.1x  utilizes  dynamic  WEP  encryption  to  protect  the  WEP  key  from  being 
decrypted.  To  solve  the  publishing  problem  for  digital  certification,  people  make  some 
changes to TLS authentication and TTLS and EAP come into exist, which enable you to 
access  the  network  by using  the  traditional  way  of  authentication:  username  and 
password.
