Figure 4-6: Advanced Security page The Passphrase can be between 8 and 63 characters For more information on WPA security, see "WPA Wireless Security" on page B-8. 4-10 202-10056-01 Configuration User Manual for the NETGEAR 108 Mbps Wireless USB 2. 0 Adapter WG111T 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 Statistics: Identifies transmit megabits per second (Mbps), transmit packets per second (Tx Packets/s), total transmitted packets, and transmit errors. Receive Statistics: Identifies receive megabits per second (Mbps), receive packets per second (Rx Packets/s), total received packets, and received errors. Advanced Settings Page To display the Advanced Settings page, click the Advanced Settings button on the Settings page. Figure 4-7: 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. Configuration 202-10056-01 4-11 User Manual for the NETGEAR 108 Mbps Wireless USB 2. 0 Adapter WG111T · · · · · Preamble: A long transmit preamble may provide a more reliable connection or slightly longer range. A short transmit preamble might give slightly better performance. 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. Wireless Mode: Select the wireless protocols you will use. Depending on your wireless adapter, you can choose some or all of the available 802. 11 wireless protocols. Note that if the wireless network you are communicating with uses the 108 Mbps 802. 11g mode, you must include that in your selection (for example, if you are using the WG111T with the NETGEAR WGT624 108 Mbps Wireless Firewall Router). 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: RTS is request to send and CTS is clear to send; their purpose is to avoid collisions. RTS/CTS will be enabled if the data frame size is larger than the threshold value set here. The maximum frame size is 2346 octets, so if the threshold is 2346, RTS/CTS will be disabled. Note: This setting is reserved for wireless testing and advanced configuration only. Do not change this setting unless you are sure you need to. The primary reason for implementing RTS/CTS is to minimize collisions between hidden stations. This occurs when users and access points are spread out and a high number of retransmissions occur on the wireless LAN. 4-12 202-10056-01 Configuration Chapter 5 Troubleshooting This chapter provides information about troubleshooting your NETGEAR 108 Mbps Wireless USB 2. 0 Adapter WG111T.
