Appendix A:  Glossary 
2x to 3x eXtended RangeTM WLAN Transmission Technology - The WLAN device with 2x to 3x 
eXtended RangeTM WLAN transmission technology make it s sensitivity up to 105 dBm, which 
gives users the ability to have robust, l onger-range wireless connections. With this 
range-enhancing technology, a 2x to 3x eXtended Range
TM based client and access point can 
maintain a connection at as much as three time s the transmission distance of traditional 802.11b 
and 802.11g products, for a coverage area that is  up to nine times greater. A traditional 802.11b 
and 802.11g product transmission distance is about 300m. A 2x to 3x eXtended Range
TM based 
client and access point can maintain a c onnection transmission distance may be up to 830m. 
802.11b -  The 802.11b standard specifies a wire less networking at 11 Mbps using 
direct-sequence spread-s pectrum (DSSS) technology and o perating in the unlicensed radio 
spectrum at 2.4GHz, and WEP encry ption for security. 802.11b networks are also referred to as 
Wi-Fi networks. 
802.11g -  specification for wire less networking at 54 M bps using direct-sequence 
spread-spectrum (DSSS) technology, using OF DM modulation and operating in the unlicensed 
radio spectrum at 2.4GHz , and backward compatibility wi th IEEE 802.11b devices, and WEP 
encryption for security. 
Access Point (AP) -  A wireless LAN transceiver or base st ation that can connect a wired LAN to 
one or many wireless devices. Access  points can also bridge to each other. 
DNS  (D omain  Name  System)  – An Internet Service that translate s the names of websites into IP 
addresses. 
Domain Name -  A descriptive name for an address or group of addresses on the Internet.   
DoS  (Denial  of Service) - A hacker attack designed to prevent your computer or network from 
operating or communicating. 
DSL  (D igital  Subscriber  Line) - A technology that allows data to be sent or received over existing 
traditional phone lines. 
ISP ( Internet  Service  Provider)  - A company that provides access to the Internet. 
MTU  (Maximum Transmission Unit ) - The size in bytes of the largest packet that can be 
transmitted. 
SSID -  A Service  Set  Identification is a thirty-two character (maximum) alphanumeric key 
identifying a wireless local area network. For 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.   
WEP  (W ired  Equivalent  Privacy)  - A data privacy mechanism bas ed on a 64-bit or 128-bit or 
152-bit shared key algorithm, as des cribed in the IEEE 802.11 standard.   
Wi-Fi -  A trade name for the 802.11b wireless networking standard, given by the Wireless 
Ethernet Compatibility Al liance (WECA, see http://www.wi-f i.net), an industry standards group 
promoting interoperabilit y among 802.11b devices. 
WLAN  (W ireless  Local Area  Network)  - A group of computers and associated devices 
communicate with each other wirelessly, which net work serving users are limited in a local area.

WPA (Wi-Fi Protected Access) - WPA is a security technology for  wireless networks that improves 
on the authentication and enc ryption features of WEP (Wired E quivalent Privacy). In fact, WPA 
was developed by the networking industry in res ponse to the shortcomings of WEP. One of the 
key technologies behind WPA is the Temporal Key Integrity Protocol (TKIP). TKIP addresses the 
encryption weaknesses of WEP. Another key com ponent of WPA is built-in authentication that 
WEP does not offer. With this feature, WPA pr ovides roughly comparable security to VPN 
tunneling with WEP, with the benef it of easier administration and use. This is similar to 802.1x 
support and requires a RADIUS server in order  to implement. The Wi-Fi Alliance will call this, 
WPA-Enterprise. One variation of WPA is called  WPA Pre Shared Key or WPA-PSK for short - this 
provides an authentication alter native to an expensive RADIUS server. WPA-PSK is a simplified 
but still powerful form of WPA most suitable  for home Wi-Fi networking. To use WPA-PSK, a 
person sets a static key or passphrase as wi th WEP. But, using TKIP, WPA-PSK automatically 
changes the keys at a preset time interval, making it much more difficult for hackers to find and 
exploit them. The Wi-Fi Alliance will call this, WPA-Personal.

Appendix C: FAQ 
1.  No lights are lit on the access point. 
It takes a few seconds for the power indicator to light up. Wait a minute and check the power light 
status on the access point if  the access point has no power. 
1)   Make sure the power cord is connected to the access point. 
2)   Make sure the power adapter is connected to  a functioning power outlet. If it is in a power 
strip, make sure the power strip is turned on.  If it is plugged directly into the wall, verify 
that it is not a switched outlet. 
3)   Make sure you are using the correct TP-L INK power adapter supplied with your access 
point. 
2.  The LAN light is not lit. 
There is a hardware connection  problem. Check these items: 
1)   Make sure the cable connectors are securely plugged in at the access point and the 
network device (hub, switch, or router). 
2)   Make sure the connec ted device is turned on. 
3)   Be sure the correct cable  is used. Use a standard Category  5 Ethernet patch cable. If the 
network device has Auto Uplink™ (MDI/MDIX)  ports, you can use either a crossover 
cable or a normal patch cable. 
3.  I cannot access the AP with a wireless capable computer. 
There is a configuration problem. Check these items: 
1)   You may not have restarted the computer  with the wireless adapter to have TCP/IP 
changes take effect. Restart the computer. 
2)   The computer with the wireless adapter ma y not have the correct TCP/IP settings to 
communicate with the network. Restart the  computer and check that TCP/IP is set up 
properly for that network. The usual setting  for Windows the Network Properties is set to 
“Obtain an IP address automatically.” 
3)   The access point’s default values may not  work with your network. Check the access 
point default configuration agains t the configuration of other devices in your network.
