Chapter 2 Hardware Installation  
2.1 Before You Begin  
Please read this User Guide carefully before installing and using the equipment. The operating  
distance range of your wireless connection can vary significantly depending on the physical  
position of the wireless devices. Factors that can weaken signals by getting in the way of your  
network’s radio waves are metal appliances or obstructions, and walls. Typical ranges vary based  
on the types of materials and background RF (radio frequency) noise in your home or office.  
In order to optimize the performance of TL-WA854RE, please follow the instructions below to  
achieve an ideal location (please make sure it is always within the wireless coverage of the  
wireless router).  
1)  
Half-way Between - Generally, the ideal location for TL-WA854RE is half-way between the  
Wireless router and Wireless Client. If the wireless signal is not satisfactory, you may place  
TL-WA854RE somewhat nearer to the Wireless router.  
2)  
3)  
No Obstacles and Spacious - Clear obstacles in the way between TL-WA854RE and  
Wireless router. It’s better to locate it in a spacious place, such as near the corridors.  
No Interference - Keep TL-WA854RE far away from wireless interference, which may come  
from electrical appliances that works in the same frequency band as TL-WA854RE, such as  
Blue tooth devices, cordless phones, microwave ovens, etc.  
4)  
3 Signal Lights - You can also find an ideal location via the signal lights on the front panel of  
TL-WA854RE. These lights show the strength of signal your range extender receives from  
the root AP. It's recommended that you choose a location where at least 3 signal lights light  
blue, in order to guarantee a good performance.  
Note:  
)
TP-LINK recommends that you connect to the Range Extender when your home network  
connection is poor, or when you want a larger wireless coverage to eliminate “dead zones”. As in  
compliance with the wireless transmission protocol, all the Range Extender devices are set to  
work in half-duplex instead of full-duplex mode. In other words, the Range Extender has to  
process one-way communication between your root Wireless router (or AP) and the terminal  
clients; so the transmission time will be double-increased, while the speed will be decreased.

Appendix B: Troubleshooting  
T1. How do I restore my Range Extender’s configuration to its factory default settings?  
There are TWO methods available to restore the factory defaults.  
Method 1:  
With the Range Extender TL-WA854RE powered on, use a pin to press and hold the RESET  
button on the rear panel for more than 8 seconds before releasing it.  
Method 2:  
Get logged in to the web-based management page of TL-WA854RE, then go to “System  
Tools -> Factory Defaults” and click “Restore”.  
Note:  
)
Once the Range Extender is reset, the current configuration settings will be lost and you will  
need to reconfigure it.  
T2. What can I do if I forget my password?  
1) Restore the Range Extender’s configuration to its factory default settings. If you don’t  
know how to do that, please refer to previous T1;  
2) Use the default user name and password: admin, admin;  
3) Try to reconfigure your Range Extender by following the instructions of this UG.  
T3. What can I do if I cannot access the web-based configuration page?  
1) Check to verify all the connections (either wireless or wired ones) are proper. If yes,  
please proceed to the next step; otherwise, check the connections again.  
2) Try to obtain an IP address and gateway; if succeed, open your web-browser, enter the  
default domain http://tplinkextender.net in the address field and get logged in.  
If you are unable to log in, please RESET the device, and then use the default IP address  
to get into the web-based configuration page, reconfigure the device.  
3) Feel free to contact our technical support, if the problem still persists.

TL-WA854RE 300Mbps Universal WiFi Range Extender User Guide  
T4. How can I know that my wireless signal has been repeated and boosted by  
TL-WA854RE?  
An easy way is to compare the signal strength of your target wireless network (symbolized by  
its SSID), with TL-WA854RE in operation vs. out of operation. Before comparison, you’d  
better make sure your computer can obtain an IP address from your target wireless network  
and thus access the Internet, either via TL-WA854RE or without.  
T5. Why does the wireless transmission rate speed down, while the wireless signal is  
stronger after repeated by TL-WA854RE?  
In compliance with the wireless transmission protocol, all the Range Extender devices are set  
to work in half-duplex instead of full-duplex mode. In other words, the Range Extender has to  
process one-way communication between your root Wireless router (or AP) and the terminal  
clients; so the transmission time will be double-increased, while the speed will be decreased.  
TP-LINK recommends that you connect to the Range Extender when your home network  
connection is poor, or when you want a larger wireless coverage to eliminate “dead zones”.

802.11b - The 802.11b standard specifies a wireless networking at 11 Mbps using  
direct-sequence spread-spectrum (DSSS) technology and operating in the unlicensed radio  
spectrum at 2.4GHz, and WEP encryption for security. 802.11b networks are also referred to  
as Wi-Fi networks.  
802.11g - specification for wireless networking at 54 Mbps using direct-sequence  
spread-spectrum (DSSS) technology, using OFDM modulation and operating in the  
unlicensed radio spectrum at 2.4GHz, and backward compatibility with IEEE 802.11b devices,  
and WEP encryption for security.  
802.11n - 802.11n builds upon previous 802.11 standards by adding MIMO (multiple-input  
multiple-output). MIMO uses multiple transmitter and receiver antennas to allow for increased  
data throughput via spatial multiplexing and increased range by exploiting the spatial diversity,  
perhaps through coding schemes like Alamouti coding. The Enhanced Wireless Consortium  
(EWC) was formed to help accelerate the IEEE 802.11n development process and promote a  
technology specification for interoperability of next-generation wireless local area networking  
(WLAN) products.

Access Point (Range Extender) - A wireless LAN transceiver or "base station" that can  
connect a wired LAN to one or many wireless devices. Access points can also bridge to each  
other.  
DNS (Domain Name System) An Internet Service that translates 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.  
¾
DSL (Digital Subscriber Line) - A technology that allows data to be sent or received over  
existing traditional phone lines.  
¾
¾
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.  
¾
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 (Wired Equivalent Privacy) - A data privacy mechanism based on a 64-bit or 128-bit or  
152-bit shared key algorithm, as described in the IEEE 802.11 standard.  
Wi-Fi –A trademark of the Wi-Fi Alliance and the brand name for products using the IEEE  
802.11 family of standards.  
WLAN (Wireless Local Area Network) - A group of computers and associated devices  
communicate with each other wirelessly, which network 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 encryption features of WEP (Wired Equivalent Privacy). In  
fact, WPA was developed by the networking industry in response 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 component of WPA is built-in  
authentication that WEP does not offer. With this feature, WPA provides roughly comparable  
security to VPN tunneling with WEP, with the benefit 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-Personal for short - this provides an authentication alternative to an expensive  
RADIUS server. WPA-Personal is a simplified but still powerful form of WPA most suitable for  
home Wi-Fi networking. To use WPA-Personal, a person sets a static key or "passphrase" as  
with WEP. But, using TKIP, WPA-Personal 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.
