2-6 Wired LAN Configuration 
 
Before all computers using wired Ethernet connection (i.e. those 
computers connect to this router’s LAN port 1 to 4 by Ethernet cable) can 
communicate with each other and access internet, they must have a valid 
IP address. 
 
There are two ways to assign IP addresses to computers: static IP address 
(set the IP address for every computer manually), and dynamic IP address 
(IP address of computers will be assigned by router automatically. It’s 
recommended for most of computers to use dynamic IP address, it will 
save a lot of time on setting IP addresses for every computer, especially 
when there are a lot of computers in your network; for servers and 
network devices which will provide services to other computer and users 
that come from Internet, static IP address should be used, so other 
computes can locate the server. 
 
Suggestions on IP address numbering plan: 
 
  If you have no idea on how to define an IP address plan for your 
network, here are some suggestions.   
 
1.  A valid IP address has 4 fields: a.b.c.d, for most of home and 
company users, it’s suggested to use 192.168.c.d, where c is 
an integer between 0 and 254, and d is an integer between 1 
and 254. This router is capable to work with up to 253 clients, 
so you can set ‘d’ field of IP address of router as 1 or 254 (or 
any number between 1 and 254), and pick a number between 0 
and 254 for field ‘c’. 
2.  In most cases, you should use ‘255.255.255.0’ as subnet mask, 
which allows up to 253 clients (this also meets router’s 
capability of working with up to 253 clients). 
3.  For all servers and network devices which will provide 
services to other people (like Internet service, print service, 
and file service), they should use static IP address. Give each 
of them a unique number between 1 and 253, and maintain a 
list, so everyone can locate those servers easily. 
4.  For computers which are not dedicated to provide specific 
service to others, they should use dynamic IP address. 
 
If you don’t really understand the descriptions listed above, don’t 
worr
y! We will provide recommended setup values below.

These settings are only available when ‘DHCP Server’ in ‘LAN IP’ 
section is ‘Enabled’, and here are descriptions of every setup items: 
 
Lease Time (1):    Please choose a lease time (the duration that every 
computer can keep a specific IP address) of every 
IP address assigned by this router from dropdown 
menu. 
 
Start IP (2):      Please input the start IP address of the IP range. 
 
End IP (3):       Please input the end IP address of the IP range.

Start IP: 192.168.1.100 
End IP: 192.168.1.200 
Domain Name: (leave it blank) 
NOTE:  
1. The number of the last field (mentioned ‘d’ field) of ‘End IP’ must be 
greater than ‘Start IP’, and can not the same with router’s IP address. 
2. The former three fields of IP address of ‘Start IP’, ‘End IP’, and ‘IP 
Address of ‘LAN IP’ section (mentioned ‘a’, ‘b’, and ‘c’ field) should be 
the same. 
3. These settings will affect wireless clients too.

2-6-3 Static DHCP Leases Table: 
 
This function allows you to assign a static IP address to a specific 
computer forever, so you don’t have to set the IP address for a 
computer, and still enjoy the benefit of using DHCP server. Maximum 
16 static IP addresses can be assigned here. 
 
(If you set ‘Lease Time’ to ‘forever’ in ‘DHCP Server’ section, you can 
also assign an IP address to a specific computer permanently, however, 
you will not be able to assign a certain IP address to a specific 
computer, since IP addresses will be assigned in random order by this 
way).  
 
 
 
Here are descriptions of every setup items: 
 
Enable Static      Check this box to enable this function, 
DHCP Leases (1):    otherwise uncheck it to disable this function. 
 
MAC Address (2):    Input the MAC address of the computer or 
network device (total 12 characters, with 
character from 0 to 9, and from a to f, like 
‘001122aabbcc’)  
 
IP address (3):    Input the IP address you want to assign to this 
computer or network device   
 
‘Add’ (4):    After you inputted MAC address and IP address 
pair, click this button to add the pair to static 
DHCP leases table. 
 
If you want to remove all characters you just entered, click ‘Clear’.

SSID (3):    This is the name of wireless router. You can type any 
alphanumerical characters here, maximum 32 
characters. SSID is used to identify your own 
wireless router from others when there are other 
wireless routers in the same area. Default SSID is 
‘default’, it’s recommended to change default SSID 
value to the one which is meaningful to you, like 
myhome, office_room1, etc. 
 
Channel Number (4): Please select a channel from the dropdown list of 
‘Channel Number’, available channel numbers are 
1 to 13 for European countries, 1 to 11 for USA. You 
can choose any channel number you want to use, 
and almost all wireless clients can locate the 
channel you’re using automatically without any 
problem. However, it’s still useful to remember the 
channel number you use, some wireless client 
supports manual channel number select, and this 
would help in certain scenario when there is some 
radio communication problem. 
 
Associated Clients (5): Click ‘Show List button, then an “Active Wireless 
Client Table” will pop up. You can see the status of 
all active wireless stations that are connecting to the 
access point. 
 
 
 
 
NOTE: If you don’t have special reason to limit the type of allowed 
wireless client, it’s recommended to choose ‘2.4 GHz (B+G+N) to 
maximize wireless client compatibility. 
NOTE: For 802.11b and 802.11g mode, the signals can be transmitted 
only by antenna 1 (The antenna in the right side of the rear panel).   
 
For 802.11n mode: The router is operating in a 1T2R Spatial 
Multiplexing MIMO configuration. 1 antenna is for signal transmitting 
and 2 antennas are for signal receiving.

2-7-1-2 Setup procedure for ‘Station-Infrastructure’: 
 
In this mode, you can connect the router to Ethernet device such us TV, 
Game player, HDD&DVD to enable the Ethernet device be a wireless 
station and join to a wireless network through an access point or AP 
router. 
 
 
 
 
Here are descriptions of every setup items: 
Band (2):  Select the band you want to use. 
 
SSID (3):  This is the name of wireless network. You can type 
the SSID of the network you would like to connect 
here. 
 
Site Survey (4):  When you use this wireless router as a wireless 
station for Ethernet network device to have wireless 
capability, you have to associate it with a working 
access point. Click ‘Select Site Survey’ button, then 
a “Wireless Site Survey Table” will pop up. It will 
list all available access points near by. You can 
select one access point in the table and it will join 
wireless LAN through this access point. 
 
 
TIPS: You can try to change channel number to another one if you 
think the data transfer rate is too slow. There could be some other 
wireless routers using the same channel, which will disturb the radio 
communication between wireless client and the wireless router.
