User Manual for the NETGEAR RangeMax™ Wireless PC Card WPN511
4-12 C onfiguration
February 2005
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.
Figure 4-8: Advanced Settings page
• Power Saving: Select On if you are using a notebook computer running on battery power.
• 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 WPN511 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.
