Wireless 11n USB Adapter 4.2.8 Wi-Fi Prote ct Se tup The primary goal of Wi-Fi Protected Setup (Wi-Fi Simple Configuration) is to simplify the security etup and management of Wi-Fi networks. This adapter supports the configuration setup using PIN s configuration method or PBC configuration method. If the wireless card supports Wi-Fi Protected Setup (WPS), you can establish a wireless connection between wireless card and router using either Push Button Configuration (PBC) method or PIN method. Here we will introduce two ways to configure the QSS

(QSS is known as rapid security settings, by pressing the wireless router and wireless card on the QSS button to automatically set up WPA2 secure connection level without the router or network adapter management software to conduct the cumbersome interface settings, greatly simplifying the operation of the wireless security settings.) Pin Code: 8-digit numbers. It is randomly generated from system

Ad-hoc wireless computers operate on a ctly with each other without the use of an access point. o referred to as an Independent Basic Service Set (IBSS) or as connected as an independe peer-to-peer basis, communicating dire Ad-hoc mode is als peer-to-peer m ode, and is useful at a departmental scale or SOHO operation. DSSS - (Direct-Se quence Spread Spectrum) - DSSS generates a redundant bit pattern for all bit pattern is called a chip (or chipping code). Even if one or more bits in e damaged during transmission, statistical techniques embedded in the receiver can the need of retransmission. To an unintended receiver, DSSS noise and is rejected (ignored) by most narrowband receivers. ver, to an intended receiver (i.e. another wireless LAN endpoint), the DSSS signal is data transmitted.

FHSS - (Frequency Hopping Spre ad Spectrum) - FHSS continuously changes (hops) the frequency of a conventional carrier several times per second according to a channels. Because a fixed frequency is not used, and only the carrier pseudo-random set of transmitter and receiver know the hop patterns, interception of FHSS is extremely difficult. Infrastructure Network - An infrastructure network is a group of computers or other devices, each with a Wireless Adapter, connected as an 802.11 wireless LAN. In infrastructure mode, the wireless devices communicate with each other and to a wired network by first going through an access point. An infrastructure wireless network connected to a wired network is referred to as a Basic Service Set (BSS). A set of two or more BSS in a single network is

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 eter for a wireless PC card. It corresponds to the ESSID in the wireless configuration param Access Point and to the wireless network name. See also Wireless Network Name and ESSID. 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. To gain access to a know the key. The key is a string of characters that you create. When WEP network, you must using WEP, you must determine the level of encryption. The type of encryption determines the key length. 128-bit encryption requires a longer key than 64-bit encryption. Keys are defined by entering in a string in HEX (hexadecimal - using characters 0-9, A-F) or ASCII (American Standard Code for Information Interchange alphanumeric characters) format. ASCII format is provided so you can enter a string that is easier to remember. The ASCII string is converted to HEX for use over the network. Four keys can be defined so that you can change keys easily.
