Configuration 202-10032-01 4-9 User Manual for the NETGEAR 11 Mbps Wireless USB Adapter MA111 Statistics Page The Statistics page provides real time and historical trend information on the data traffic and performance of your wireless adapter. · · · · Transmit/Receive Performance (%): A real time graph identifying the total, receive, and transmit utilization as a percentage the total possible. Total/Receive/Transmit Graph: Identifies the trend of transmit/receive data communications over time. Transmit Kbits and Transmit Packets: Identifies transmit kilobits per second, and transmit packets per second (Tx Packets/s), total transmitted packets, and transmit errors. Receive Kbits and Receive Packets: Identifies receive kilobits per second, receive packets per second (Rx Packets/s), total received packets, and received errors. Advanced Settings Page The Advanced settings should not require adjustment. Except for the power saving setting, changing any of the settings incorrectly on this page could cause your wireless connection to fail. · · · · · Transmit Rate: The default setting is Fully Automatic. Transmit Power: Lowering the output power level lets you reduce the chance of interference with other nearby access points, but reduces the range of your adapter. Preamble Type: A long transmit preamble may provide a more reliable connection or slightly longer range. Fragmentation Threshold: This is the maximum packet size used for fragmentation. Packets larger than the size programmed in this field will be fragmented. The Fragmentation Threshold value must be larger than the RTS/CTS Threshold value. RTS/CTS Threshold: The packet size that is used to determine whether to use the CSMA/CD (Carrier Sense Multiple Access with Collision Detection) mechanism or the CSMA/CA (Carrier Sense Multiple Access with Collision Avoidance) mechanism for packet transmission. CSMA/CD is slightly more efficient. · 4-10 202-10032-01 Configuration Appendix A Technical Specifications This appendix provides technical specifications for the NETGEAR 11 Mbps Wireless USB Adapter MA111.

Wireless Networking Overview The MA111 Wireless USB Adapter conforms to the Institute of Electrical and Electronics Engineers (IEEE) 802. 11b standard for wireless LANs (WLANs). On an 802. 11b wireless link, data is encoded using direct-sequence spread-spectrum (DSSS) technology and is transmitted in the unlicensed radio spectrum at 2. 4GHz. The maximum data rate for the wireless link is 11 Mbps, but it will automatically back down from 11 Mbps to 5. 5, 2, and 1 Mbps when the radio signal is weak or when interference is detected. The 802. 11 standard is also called Wireless Ethernet or Wi-Fi by the Wireless Ethernet Compatibility Alliance (WECA, see http://www. wi-fi. net), an industry standard group promoting interoperability among 802. 11 devices. The 802. 11 standard offers two methods for configuring a wireless network - ad-hoc and infrastructure. Infrastructure Mode With a wireless Access Point, you can operate the wireless LAN in the infrastructure mode. [. . . ] These names are alphanumeric names, up to 16 characters in length.
