User Manual for the NETGEAR 54 Mbps Wireless USB 2.0 Adapter WG121

Configuration 4-9

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

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.

• 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 WG121 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: 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.
