16 4.3 WEP Encryption WEP is an authentication algorithm, which protects unauthorized Wireless LAN users against eavesdropping. The Authentication type and WEP key must be the same on the wireless stations within the network. This adapter supports 64/128-bit WEP Encryption. With this function, your data will be transmitted over the Wireless network securely. Parameter Description Authentication Mode This setting has to be consistent with the wireless stations that the adapter intends to connect to. •Open System – No authentication is needed among the wireless stations. •Shared Key – Only wireless stations using a shared key (WEP Key identified) are allowed to connect to each other. Setup the network using the same key as the wireless stations use that the adapter intends to connect to. •Auto – Auto switch the authentication algorithm depending on the wireless stations that the adapter is connecting to. Key Length You may select 64-bit or 128-bit to encrypt transmitted data. Larger key length will provide higher level of security, but the throughput will be lower. Default Key ID Select one of the keys (1~4) as the encryption key.
17 Key1 ~ Key4 The keys are used to encrypt data transmitted in the wireless network. Fill the text box by following the rules below. •64-bit – Input 10 digit Hex values (in the “A-F”, “a-f” and “0-9” range) as the encryption keys. For example: “0123456aef“. •128-bit – Input 26 digit Hex values (in the “A-F”, “a-f” and “0-9” range) as the encryption keys. For example: “01234567890123456789abcdef“.
18 4.4 Advanced Setting The “Advanced Setting” allows user to enable/disable power saving mode, setup the fragmentation threshold and RTS/CTS threshold of the adapter. Parameter Description Enable auto power saving Check this box to enable power saving mode. You may control the power consumption of the adapter by adjusting the save power level from 1 to 4. The higher power save level selected, the lower power used. Note that when lower power is supplied it may slow down the transmission rate of the adapter. Fragementation Threshold This value defines the maximum size of packets. Any packet size larger than the value will be fragmented. If you have decreased this value and experience high packet error rates, you can increase it again, but it will likely decrease overall network performance. Select a setting within a range of 256 to 2305 bytes. Minor change is recommended. RTS / CTS Threshold Minimum packet size required for an RTS/CTS (Request To Send/Clear to Send). For packets smaller than this threshold, an RTS/CTS is not sent and the packet is transmitted directly to the WLAN. Select a setting within a range of 0 to 2305 bytes. Minor change is recommended
19 Troubleshooting This chapter provides solutions to problems usually encountered during the installation and operation of the adapter. 1. What is the IEEE 802.11b standard？ The IEEE 802.11b Wireless LAN standard subcommittee formulates the standard for the industry. The objective is to enable wireless LAN hardware from different manufactures the ability to communicate. 2. What does IEEE 802.11 feature support？ The product supports the following IEEE 802.11 functions: • CSMA/CA plus Acknowledge Protocol • Multi-Channel Roaming • Automatic Rate Selection • RTS/CTS Feature • Fragmentation • Power Management 3. What is Ad-hoc？ An Ad-hoc integrated wireless LAN is a group of computers, each has a Wireless LAN adapter, connected as an independent wireless LAN. An Ad-hoc wireless LAN is applicable at a departmental scale for a branch or SOHO operation. 4. What is Infrastructure？ An integrated wireless and wireless/wired LAN is called an Infrastructure configuration. Infrastructure is applicable to enterprise scale for wireless access to central database, or wireless application for mobile workers. 5. What is BSS ID？ 5
20 A specific Ad hoc LAN is called a Basic Service Set (BSS). Computers in a BSS must be configured with the same BSS ID. 6. What is WEP？ WEP is Wired Equivalent Privacy, a data privacy mechanism based on a 40 bit shared key algorithm, as described in the IEEE 802 .11 standard. 7. What is TKIP? TKIP is a quick-fix method to quickly overcome the inherent weaknesses in WEP security, especially the reuse of encryption keys. TKIP is involved in the IEEE 802.11i WLAN security standard, and the specification might be officially released in early 2003. 8. What is AES? AES (Advanced Encryption Standard), a chip-based security, has been developed to ensure the highest degree of security and authenticity for digital information, wherever and however communicated is stored, while making more efficient use of hardware and/or software than previous encryption standards. It is also included in the IEEE 802.11i standard. Compared with AES, TKIP is a temporary protocol for replacing WEP security until manufacturers implement AES at the hardware level. 9. What is IEEE 802.1x? 802.1x is an IEEE standard that provides an authentication framework for 802-based LANs. 802.1x will let wireless LANs be scaled by allowing centralized authentication of wireless users or stations. Based on the 802.1x framework, any wireless stations try to connect to an Access Point or Router will be authenticated by an Authentication Server. The Authentication Server identifies the wireless station by a set of user name and password. Only wireless stations providing a correct user name and password can connect to the Access Point or Router and access to the network.
21 10. Can Wireless products support printer sharing？ Wireless products perform the same function as LAN products. Therefore, Wireless products can work with Netware, Windows 2000, or other LAN operating systems to support printer or file sharing. 11. Would the information be intercepted while transmitting on air？ WLAN features two-fold protection in security. On the hardware side, as with Direct Sequence Spread Spectrum technology, it has the inherent security feature of scrambling. On the software side, WLAN series offer the encryption function (WEP) to enhance security and Access Control. Users can set it up according to their needs. 12. What is DSSS？What is FHSS？And what are their differences？ Frequency-hopping spread-spectrum (FHSS) uses a narrowband carrier that changes frequency in a pattern that is known to both transmitter and receiver. Properly synchronized, the net effect is to maintain a single logical channel. To an unintended receiver, FHSS appears to be short-duration impulse noise. Direct-sequence spread spectrum (DSSS) generates a redundant bit pattern for each bit to be transmitted. This bit pattern is called a chip (or chipping code). The longer the chip is, the greater the probability that the original data can be recovered. Even if one or more bits in the chip are damaged during transmission, statistical techniques embedded in the radio can recover the original data without-the need for retransmission. To an unintended receiver, DSSS appears as low power wideband noise and is rejected (ignored) by most narrowband receivers.
22 13. What is Spread Spectrum？ Spread Spectrum technology is a wideband radio frequency technique developed by the military for use in reliable, secure, mission-critical communication systems. It is designed to trade off bandwidth efficiency for reliability, integrity, and security. In other words, more bandwidth is consumed than in the case of narrowband transmission, but the trade off produces a signal that is, in effect, louder and thus easier to detect, provided that the receiver knows the parameters of the spread-spectrum signal being broadcast. If a receiver is not tuned to the right frequency, a spread –spectrum signal looks like background noise. There are two main alternatives, Direct Sequence Spread Spectrum (DSSS) and Frequency Hopping Spread Spectrum (FHSS).
