Once connected, the access point allows you to access wireless LAN and wired LAN (Ethernet). The Channel field turns to Auto if the connection is based on Infrastructure.Ad Hoc – Ad Hoc means to communicate directly with other wireless clients without using an access point. An “Ad Hoc” network can be setup quickly and easily without pre-planning, for example, sharing meeting notes between attendants in a meeting room.Network Name (SSID)SSID stands for “Service Set Identifier”, which is a string used to identify a wireless LAN. Use the SSID to connect with a known access point. You can enter a new SSID or select one from the drop-down list box. If you get connected by designating the SSID, you are only to connect the AP with the SSID you assigned. If the AP is removed from the network, your WLAN Adapter does not roam automatically to other APs.

ASUS WLAN Adapter 19Chapter 3 - Software ReferenceChapter 3Software ReferenceNetwork AuthenticationSince there is no precise bound in wireless LANs, the WLAN users need to implement certain mechanism to provide security solution. The Authentication policies in this tab provide protection of different levels such as Open, Shared, WPA-PSK, WPA, and WPA2.Open - Select this option to make the network operate on Open System mode, which use no authentication algorithm. Open stations and APs can authenticate with each other without checking any WEP Key, even if there is.Shared - Select this option to make the network operate on Shared key mode. In a Share Key Authentication system, four-step exchange of frames is required to validate that the station is using the same WEP Key as the access point.WPA-PSK/ WPA2-PSK - Select this option to enable WPA Pre-Shared Key under Infrastructure mode. It enables communication between your client and APs using WPA-PSK/WPA2-PSK encryption mode.WPA/ WPA2 - The network is operating in IEEE 802.1x authentication mode. This mode is for environments with RADIUS (Remote Access Dial-in User Service). In a RADIUS environment, three Extensible Authentication Protocol (EAP) are supported, including PEAP, EPA/TLS, and LEAP.&RQÀJ(QFU\SWLRQThis page enables you to configure the Wireless LAN Adapter encryption settings. For data confidentiality in a wireless environment, IEEE 802.11 specifies a Wired Equivalent Privacy (WEP) algorithm to offer transmission privacy. The WEP uses keys to encrypt and decrypt data packets. The encryption process can scramble frame bits to avoid disclosure to others. The WPA/WPA2 is improved security system for 802.11 which are developed to overcome the weakness of the WEP protocol.

To compensate, a new physical-layer encoding technology was designed that departs from the traditional direct-sequence technology being deployed today. This technology is called COFDM (coded OFDM). COFDM was developed specifically for indoor wireless use and offers performance much superior to that of spread-spectrum solutions. COFDM works by breaking one high-speed data carrier into several lower-speed subcarriers, which are then WUDQVPLWWHG LQSDUDOOHO(DFK KLJKVSHHGFDUULHULV0+] ZLGHDQGLV EURNHQXS LQWR  VXEFKDQQHOV HDFK DSSUR[LPDWHO\  .+] ZLGH &2)'0 XVHV  RIthese subchannels for data, while the remaining four are used for error correction.

A DNS server keeps a database of host computers and their respective domain names and IP addresses, so that when a user enters a domain name into the Internet browser, the user is sent to the proper IP address. The DNS server address used by the computers on your home network is the location of the DNS server your ISP has assigned.DSL Modem (Digital Subscriber Line)A DSL modem uses your existing phone lines to transmit data at high speeds.Direct-Sequence Spread Spectrum (for 802.11b)Spread spectrum (broadband) uses a narrowband signal to spread the transmission over a segment of the radio frequency band or spectrum. Direct-sequence is a spread spectrum technique where the transmitted signal is spread over a particular frequency range.
ASUS WLAN Adapter 31Chapter 5Chapter 5 - GlossaryGlossaryDirect-sequence systems communicate by continuously transmitting a redundant pattern of bits called a chipping sequence. Each bit of transmitted data is mapped into chips and rearranged into a pseudorandom spreading code to form the chipping sequence. The chipping sequence is combined with a transmitted data stream to produce the output signal.Wireless mobile clients receiving a direct-sequence transmission use the spreading code to map the chips within the chipping sequence back into bits to recreate the original data transmitted by the wireless device.

The ratio of chips per bit is called the spreading ratio. A high spreading ratio increases the resistance of the signal to interference. A low spreading ratio increases the bandwidth available to the user. The wireless device uses a constant chip rate of 11Mchips/s for all data rates, but uses different modulation schemes to encode more bits per chip at the higher data rates. The wireless device is capable of an 11 Mbps data transmission rate, but the coverage area is less than a 1 or 2 Mbps wireless device since coverage area decreases as bandwidth increases.EncryptionThis provides wireless data transmissions with a level of security. This option allows you to specify a 64-bit or a 128-bit WEP key. A 64-bit encryption contains 10 hexadecimal digits or 5 ASCII characters. A 128-bit encryption contains 26 hexadecimal digits or 13 ASCII characters.64-bit and 40-bit WEP keys use the same encryption method and can interoperate on wireless networks.
