Read the descriptions below to solve your problems. 1. My computer does not recognize the Cardbus. Make sure the Cardbus is properly inserted into the CardBus slot. Note that the Cardbus can be inserted either way, but is correctly only when it is inserted so that the Instant Wireless logo on the front of the Cardbus cannot be seen. If in doubt, try inserting the Cardbus both ways. The Cardbus will slide in further when it is correct. 2. The Cardbus does not work properly. Reinsert the Cardbus into your notebooks CardBus slot. A beep should be heard if the Cardbus is properly inserted. For non-Windows environments, make sure that a CARDBUS card service driver is installed on your PC. Open the Control Panel and click the PC Card. Check whether it has a Cardbus in one of the sockets or not. If you find the Cardbus in one of the sockets, it means that the Cardbus has been detected properly. If you see a yellow question mark, the resources are in conflict. Right-click My Computer and select Properties. Select Device Manager and click the Network Adapter. You will find the WLAN 802.11a+b+g Cardbus if it is installed successfully. If you see the yellow exclamation mark, the resources are in conflict. Click Cardbus and then click Cardbus service. You will see the status of the Cardbus. If there is a yellow question mark please check the following:
Make sure that your notebook has a free IRQ. Make sure that you have inserted the right Cardbus and installed the proper driver. If the Cardbus does not function after attempting the above steps, remove the Cardbus and do the following:
Uninstall the driver software from your PC. Restart your PC and repeat the hardware and software installation as specified in this User Guide. 28 3. I cannot communicate with a wired computer linked via an access point in the infrastructure configuration. Make sure that the notebook PC is powered on. Make sure that the Cardbus is configured with the same SSID and security options as the other computers in the infrastructure configuration. Co Frequently Asked Questions 1. Can I run an application from a remote computer over the wireless network?
This will depend on whether or not the application is designed to be used over a network. Consult the applications user guide to determine if it supports operation over a network. 2. Can I play computer games with other members of the wireless network?
Yes, as long as the game supports multiple players over a LAN (local area network). Refer to the games user guide for more information. 3. What is Spread Spectrum?
Spread Spectrum technology is a wideband radio frequency technique developed by the military for use in reliable, secure, mission-critical communications 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). 4. 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, 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 29 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. 5. 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 offers the encryption function (WEP) to enhance security and access control. 6. What is WEP?
WEP is Wired Equivalent Privacy, a data privacy mechanism based on a 64-bit or 128-bit shared key algorithm, as described in the IEEE 802.11 standard. 7. What is infrastructure mode?
When a wireless network is set to infrastructure mode, the wireless network is configured to communicate with a wired network through a wireless access point. 8. What is roaming?
Roaming is the ability of a portable computer user to communicate continuously while moving freely throughout an area greater than that covered by a single access point. Before using the roaming function, the workstation must make sure that it is the same channel number with the access point of dedicated coverage area. To achieve true seamless connectivity, the wireless LAN must incorporate a number of different functions. Each node and access point, for example, must always acknowledge receipt of each message. Each node must maintain contact with the wireless network even when not actually transmitting data. Achieving these functions simultaneously requires a dynamic RF networking technology that links access points and nodes. In such a system, the users end node undertakes a search for the best possible access to the system. First, it evaluates such factors as signal strength and quality, as well as the message load currently being carried by each access point and the distance of each access point to the wired backbone. Based on that information, the node next selects the right access point and registers its address. Communications between end node and host computer can then be transmitted up and down the backbone. As the user moves on, the end nodes RF transmitter regularly checks the system to determine whether it is in touch with the original access point or whether it should seek a new one. When a node no longer receives acknowledgment from its 30 original access point, it undertakes a new search. Upon finding a new access point, it then re-registers, and the communication process continues. 9. What is ISM band?
The FCC and their counterparts outside of the U.S. have set aside bandwidth for unlicensed use in the ISM (Industrial, Scientific and Medical) band. Spectrum in the vicinity of 2.4 GHz, in particular, is being made available worldwide. This presents a truly revolutionary opportunity to place convenient high-speed wireless capabilities in the hands of users around the globe. 31 Appendix B: Specification Item Key specifications Main Chipset Frequency range U-NII: 2.412 ~ 2.462Ghz, 5.15 ~ 5.35Ghz, 5.725 ~ 5.825Ghz
