25 Chapter 5: Configuring the Dual-Band Wireless A+G Broadband Router The Wireless Tab - Advanced Wireless Settings Dual-Band Wireless A+G Broadband Router Router’s ability to catch all Wireless-G transmissions but will severely decrease performance. If you do not want to use CTS Protection Mode at all, select Disabled. Frame Burst Mode. Enabling this option should provide your network with greater performance, depending on the manufacturer of your wireless products. If you are not sure how to use this option, keep the default, Enabled. Beacon Interval. The default value is 100. The Beacon Interval value indicates the frequency interval of the beacon. A beacon is a packet broadcast by the Router to synchronize the wireless network. DTIM Interval. This value indicates the interval of the Delivery Traffic Indication Message (DTIM). A DTIM field is a countdown field informing clients of the next window for listening to broadcast and multicast messages. When the Router has buffered broadcast or multicast messages for associated clients, it sends the next DTIM with a DTIM Interval value. Its clients hear the beacons and awaken to receive the broadcast and multicast messages. The default value is 1. Fragmentation Threshold. This value specifies the maximum size for a packet before data is fragmented into multiple packets. If you experience a high packet error rate, you may slightly increase the Fragmentation Threshold. Setting the Fragmentation Threshold too low may result in poor network performance. Only minor reduction of the default value is recommended. In most cases, it should remain at its default value of 2346. RTS Threshold. Should you encounter inconsistent data flow, only minor reduction of the default value, 2347, is recommended. If a network packet is smaller than the preset RTS threshold size, the RTS/CTS mechanism will not be enabled. The Router sends Request to Send (RTS) frames to a particular receiving station and negotiates the sending of a data frame. After receiving an RTS, the wireless station responds with a Clear to Send (CTS) frame to acknowledge the right to begin transmission. The RTS Threshold value should remain at its default value of 2347.

55 Appendix A: Troubleshooting Frequently Asked Questions Dual-Band Wireless A+G Broadband Router How do I get mIRC to work with the Router? Under the Port Forwarding tab, set port forwarding to 113 for the PC on which you are using mIRC. Can the Router act as my DHCP server? Yes. The Router has DHCP server software built-in. 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 application’s documentation to determine if it supports operation over a network. What is the IEEE 802.11a standard? It is one of the IEEE standards for wireless networks. The 802.11a standard allows wireless networking hardware from different manufacturers to communicate, provided that the hardware complies with the 802.11a standard. The 802.11a standard states a maximum data transfer rate of 54Mbps and an operating frequency of 5GHz. What is the IEEE 802.11b standard? It is one of the IEEE standards for wireless networks. The 802.11b standard allows wireless networking hardware from different manufacturers to communicate, provided that the hardware complies with the 802.11b standard. The 802.11b standard states a maximum data transfer rate of 11Mbps and an operating frequency of 2.4GHz. What is the IEEE 802.11g standard? It is one of the IEEE standards for wireless networks. The 802.11g standard allows wireless networking hardware from different manufacturers to communicate, provided that the hardware complies with the 802.11g standard. The 802.11g standard states a maximum data transfer rate of 54Mbps and an operating frequency of 2.4GHz. What IEEE 802.11a features are supported? The product supports the following IEEE 802.11a functions: •OFDM protocol •Multi-Channel Roaming •Automatic Rate Selection •RTS/CTS feature •Fragmentation 56 Appendix A: Troubleshooting Frequently Asked Questions Dual-Band Wireless A+G Broadband Router What IEEE 802.11b features are supported? The product supports the following IEEE 802.11b functions: •CSMA/CA plus Acknowledge protocol •Multi-Channel Roaming •Automatic Rate Selection •RTS/CTS feature •Fragmentation •Power Management What IEEE 802.11g features are supported? The product supports the following IEEE 802.11g functions: •CSMA/CA plus Acknowledge protocol •OFDM protocol •Multi-Channel Roaming •Automatic Rate Selection •RTS/CTS feature •Fragmentation •Power Management What is ad-hoc mode? When a wireless network is set to ad-hoc mode, the wireless-equipped computers are configured to communicate directly with each other. The ad-hoc wireless network will not communicate with any wired network. 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. What is roaming? Roaming is the ability of a portable computer to communicate continuously while moving freely throughout an area greater than that covered by a single access point. Before using the roaming function, the user must make sure that the workstation uses the same channel number as the access point of the 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 user’s 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 57 Appendix A: Troubleshooting Frequently Asked Questions Dual-Band Wireless A+G Broadband Router 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 node’s 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 original access point, it undertakes a new search. Upon finding a new access point, it then re-registers, and the communication process continues. 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. 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). 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 sync…
