Compact Wireless-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 Appendix A: Troubleshooting 55 Frequently Asked Questions

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
