Understanding the 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.

•Power Saving: Select Normal or Max if you are running on battery power.

•Preamble: A long preamble may provide a more reliable connection or slightly longer range.

•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. You can choose from the available 802.11 wireless protocols. Note that if the wireless network you are communicating with uses the Ultra-G mode, you must include that in your selection (for example, if you are using the WG511U with the NETGEAR WG624U 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.
