T6. Will the extender work if I connect the ETHERNET port of it to the router

via Ethernet cable?

Sorry, it won’t 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.

T7. Why does the wireless transmission rate speed down, while the wireless

signal is stronger after repeated by the extender?

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”.

● 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.

● 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

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

Appendix

"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, WPAPersonal.
