Before You Begin Basic Requirements Quick Setup Before You Begin Please read this guide carefully before installing and using the device. 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 networks 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-WA850RE, please follow the instructions below to achieve an ideal location (please make sure it is always within the wireless coverage of the wireless router). Half-way Between - Generally, the ideal location for TL-WA850RE is half-

way between the Wireless router and Wireless Client. If the wireless signal is not satisfactory, you may place TL-WA850RE somewhat nearer to the Wireless router. No Obstacles and Spacious - Clear obstacles in the way between TL-

WA850RE and Wireless router. Its better to locate it in a spacious place, such as near the corridors. No Interference - Choose a location away from Bluetooth devices and other household electronics, such as cordless phone, microwave, and baby monitor, etc., to minimize signal interference. Connect the Extender to the Internet 4 Basic Requirements Place your extender in a well-ventilated place far from direct sunlight, any heater or heating vent. Leave at least 2 inches (5cm) space around the device for heat dissipation. Turn off your extender and unplug the power adapter in a lighting storm to avoid damage. Use Web browser, such as Microsoft Internet Explorer 5.0 or above, Netscape Navigator 6.0 or above. Quick Setup Using WPS (Wi-Fi Protected Setup) Your router should support WPS. Otherwise, please use Using your web browser. 1 Power On Plug in next to your router. Operating temperature of the extender should be 0~40 (32

~104). Operating humidity of the extender should be 10%~90%RH (Non-

condensing). 2 Connect 1) Press the WPS button on your router. Connect the Extender to the Internet 5 If the RE LED does not change from flashing to solid, please refer to Using your Web Browser. Some ISP gateways disable the WPS function by default, if the WPS method fails, please refer to Using your Web Browser. 3 Relocate Plug the extender into an electrical outlet about halfway between your router (Host Network) and the Wi-Fi dead zone. Wait until the

How do I restore my extenders configuration to its factory default settings?

There are two ways to reset the extender:

Option One: With the extender powered on, use a pin to press and hold the RESET button until all LEDs turn on momentarily, then release the button. Option Two: Restore the default settings from System Tools > Restore

& Backup of the extender's Web-based Management page. Once the 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 login password?

Restore the extenders configuration to its factory default settings. If you dont know how to do that, please refer to previous T1;

Use the default username and password: admin, admin;

Try to reconfigure your extender by following the instructions of this guide. T3. What can I do if I cannot access the web-based configuration page?

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. Try to obtain an IP address and gateway; if succeed, open your web-

browser, enter the default domain http://tplinkrepeater.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. Feel free to contact our technical support, if the problem still persists. T4. How can I know that my wireless signal has been repeated and boosted by TL-WA850RE?

An easy way is to compare the signal strength of your target wireless network (symbolized by its SSID), with TL-WA850RE in operation vs. out of operation. Before comparison, youd better make sure your computer can obtain an IP address from your target wireless network and thus access the Internet, either via TL-WA850RE or without. T5. Will the extender work if I connect the ETHERNET port of it to the router via Ethernet cable?

Sorry, it wont work. The extender is designed to connect wirelessly to the router, while the ETHERNET port is designed to connect with a wired device, like Internet TV, Gaming console, DVR and so on. T6. Why does the wireless transmission rate speed down, while the wireless signal is stronger after repeated by TL-WA850RE?

In compliance with the wireless transmission protocol, all the extender devices are set to work in half-duplex instead of full-duplex mode. In other words, the 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 extender when your home network connection is poor, or when you want a larger wireless coverage to eliminate dead zones.

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. 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. 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. ISP (Internet Service Provider) - A company that provides access to the Internet. MTU (Maximum Transmission Unit) - The size in bytes of the largest Appendix 29 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 (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. Appendix 30
