TL-WA850RE 300Mbps Universal WiFi Range Extender User Guide 4 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-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). 1) 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. 2) No Obstacles and Spacious - Clear obstacles in the way between TL-WA850RE and Wireless router. It’s better to locate it in a spacious place, such as near the corridors. 3) No Interference - Keep TL-WA850RE far away from wireless interference, which may come from electrical appliances that works in the same frequency band as TL-WA850RE, 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-WA850RE. 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.
TL-WA850RE 300Mbps Universal WiFi Range Extender User Guide 5 2.2 Basic Requirements  Place your Range 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 Range 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.  Operating temperature of the Range Extender should be 0℃~40℃ (32℉~104℉).  Operating humidity of the Range Extender should be 10%~90%RH (Non-condensing). 2.3 Connecting the Device Figure 2-1 Typical connection of TL-WA850RE To establish a typical connection of the Range Extender, please take the following steps: 1.

Here you can create a wireless local area network just through a few settings. Wireless Settings is used for the configuration of some basic parameters of the Range Extender. Wireless Security provides three different security types to secure your data and thus provide greater security for your wireless network. MAC filtering allows you to control the access of wireless stations to the Range Extender. Wireless Advanced allows you to configure some advanced parameters for the Range Extender. Throughput Monitor helps to watch wireless throughput information Wireless statistics enables you to get detailed information about the current connected wireless stations. There are six submenus under the Wireless menu (shown in Figure 4-17): Wireless Settings, Wireless Security, Wireless MAC Filtering, Wireless Advanced, Wireless Statistics and Throughput Monitor. Click any of them, and you will be able to configure the corresponding function. The detailed explanations for each submenu are provided below. Figure 4-17 Wireless menu 4.6.1 Wireless Settings Selecting Wireless > Wireless Settings will enable you to configure the basic settings for your wireless network on the screen below (Figure 4-18).This page allows you to configure the wireless mode for your device. Two operation modes are supported here, including Range Extender mode 1, and Range Extender mode 2. The only difference between these two modes is that Range Extender mode 1 has WDS disabled while Range Extender mode 2 has WDS enabled. In both modes, the Range Extender will relay data to an associated root AP. The range extender function is enabled meanwhile. The wireless repeater relays signal between its stations and the root AP for greater wireless range. Since the configurations are almost the same in either operation mode, here we just take that in Range Extender mode 1 for example.

TL-WA850RE 300Mbps Universal WiFi Range Extender User Guide 36 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-WA850RE 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-WA850RE, 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.
TL-WA850RE 300Mbps Universal WiFi Range Extender User Guide 37 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. 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, 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-WA850RE or without. T5. Will the Range Extender work if I connect the ETHERNET port of it to the router via Ethernet cable? Sorry, it won’t work. The Range 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 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”.

TL-WA850RE 300Mbps Universal WiFi Range Extender User Guide 39 Appendix D: Glossary  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.  DSL (Digital 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 (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.
TL-WA850RE 300Mbps Universal WiFi Range Extender User Guide 40  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.
