)  Note: 
Your opposite side should call your WA N IP, which is displayed on the 
“Status” page.  
4)  How to enable DMZ Host: Login to the router , click the “Forwarding” menu on the left of 
your browser, and click DMZ submenu. On  the DMZ page, click “Enable” radio and 
type your IP address into the “DMZ Host IP  Address” field, using 192.168.1.169 as an 
example, remember to cl ick the Save” button.

4.  I want to build a WEB Server on the LAN, what should I do?  1)  Because the WEB Server port 80 will inte rfere with the WEB management port 80 on the 
router, you must change the WEB management  port number to avoid interference. 
2)  To change the WEB management port number: Logi n to the router, click the “Security” 
menu on the left of your browser, and click Remote Management  submenu. On the 
Remote Management page, type a port number  except 80, such as 88, into the Web 
Management Port field. Click “Save” and reboot the router.

If the above configuration takes effect,  to configure to the router by typing 
http://192.168.1.1:88
 (the router’s LAN IP address:  Web Management Port) in the address 
field of the Web browser. 
3)  Login to the router, click the “Forwarding” me nu on the left of your browser, and click the 
Virtual Servers submenu. On  the Virtual Server page, click  Add New, then on the 
“Add or Modify a Virtual Server” page, enter “8 0” into the blank behind the “Service Port”, 
and your IP address behind the IP Address,  assuming 192.168.1.188 for an example, 
remember to “Enable” and “Save”.

 742)  Make sure that the wireless stations
 SSID accord with the routers SSID. 
3)  Make sure the wireless stations have  right KEY for encryption when the router is 
encrypted. 
4)  If the wireless connection is ready, but you can’t access the router, check the IP Address  of your wireless stations.

Appendix B: Configuring the PC 
In this section, we’ll introduce how to install and configure the TCP/IP correctly in Windows XP. 
First make sure your Ethernet Adapter is wo rking, refer to the adapter’s manual if needed. 
1.  Install TCP/IP component  1)  On the Windows taskbar, click the  Start button, point to Settings , and then click Control 
Panel . 
2) Click the  Network and Internet Connections  icon, and then click on the Network 
Connections  tab in the appearing window. 
3)  Right click the icon that showed below, select Properties on the prompt page.

Appendix D: Glossary 
¾ 2x to 3x eXtended Range™ WLAN Transmission Technology -  The WLAN device with 2x 
to 3x eXtended Range
™ WLAN transmission technology make  its sensitivity up to 105 dB, 
which gives users the ability to have robus t, longer-range wireless connections. With this 
range-enhancing technology, a 2x to 3x eXtended Range
™ based client and access point can 
maintain a connection at as much as three  times the transmission distance of traditional 
802.11b and 802.11g products, for a coverage ar ea that is up to nine times greater. A 
traditional 802.11b and 802.11g product transmissi on distance is about 300m, a 2x to 3x 
eXtended Range
™ based client and access point c an maintain a connection transmission 
distance may be up to 830m. 
¾  802.11b -  The 802.11b standard specifies a wire less networking at 11 Mbps using 
direct-sequence spread-s pectrum (DSSS) technology and oper ating in the unlicensed radio 
spectrum at 2.4GHz, and WEP enc ryption for security. 802.11b networks are also referred to 
as Wi-Fi networks. 
¾  802.11g -  specification for wireless network ing at 54 Mbps using direct-sequence 
spread-spectrum (DSSS) tec hnology, using OFDM modulation and operat ing in the 
unlicensed radio spectrum at  2.4GHz, and backward compatibility with IEEE 802.11b devices, 
and WEP encryption for security. 
¾  DDNS  (D ynamic  Domain  Name  System)  - The capability of assigning a fixed host and 
domain name to a dynamic Internet IP Address.   
¾  DHCP  (D ynamic  Host  Configuration  Protocol)  - A protocol that autom atically configure the 
TCP/IP parameters for the all the PC(s ) that are connected to a DHCP server. 
¾ DMZ  (D em ilitarized  Zone) - A Demilitarized Zone allows one lo cal host to be exposed to the 
Internet for a special-purpose service such  as Internet gaming or videoconferencing. 
¾ DNS  (D omain  Name  System)  – An Internet Service that translates the names of websites into 
IP addresses. 
¾  Domain Name -  A descriptive name for an address or group of addresses on the Internet.   
¾ DoS  (D enial  of Service) -  A hacker attack designed to prevent your computer or network from

¾ MTU  (Maximum Transmission Unit ) - The size in bytes of t he largest packet that can be 
transmitted. 
¾  NAT  (N etwork  Address  Translation)  - NAT technology translates IP addresses of a local area 
network to a different IP address for the Internet. 
¾  PPPoE  (P oint to P oint Protocol  over Ethernet)  - PPPoE is a protocol for connecting remote 
hosts to the Internet over  an always-on connection by simulating a dial-up connection. 
¾ SSID -  A Service  Set  Identification is a thirty-two char acter (maximum) alphanumeric key 
identifying a wireless local area network. Fo r the wireless devices in a network to 
communicate with each other, all devices must be  configured with the same SSID. This is 
typically the configuration parameter for a wireless PC card. It corresponds to the ESSID in 
the wireless Access Point and to the wireless network name.   
¾  WEP  (W ired  Equivalent  Privacy)  - A data privacy mechanism based on a 64-bit or 128-bit or 
152-bit shared key algorithm, as des cribed in the IEEE 802.11 standard.   
¾ Wi-Fi -  A trade name for the 802.11b wireless network ing standard, given by the Wireless 
Ethernet Compatibility Allianc e (WECA, see http://www.wi-f i.net), an industry standards 
group promoting interoper ability among 802.11b devices. 
¾ WLAN  (W ireless  Local Area  Network)  - A group of computers and associated devices
