Field	Description
Basic Rates	Sets the wireless data transmission rates that all wireless LAN clients must be able to receive:
	• 1, 2 Mbps. The SBG1000 attempts to associate at 2 Mbps. Use this setting if the wireless
	LAN has only legacy IEEE 802.11b clients.
	• 1, 2, 5.5, and 11 Mbps. The SBG1000 attempts to associate at 11 Mbps. If there are
	obstacles or interference, it automatically steps down to the highest rate that allows
	transmission. Use this setting if the wireless LAN has fully-compliant IEEE 802.11b clients.
	The default is 1, 2, 5.5, and 11 Mbps.
Transmit Power	Sets the transmit power on the SBG1000 wireless access point — 1, 2, 5, 10, 25, 50, or 100
	mW. The default is 32 mW. Transmit power control is an optional IEEE 802.11b feature.
RTS Threshold	The Request To Send Threshold sets the packet size at which the access point issues an RTS
	before sending the packet. A low RTS can help when many clients are associated with the
	SBG1000 or when the clients are far apart and can detect the SBG1000 but not each other.
	The value can be 0 to 2347 bytes. The default is 2347.
Fragmentation	Sets the size at which packets are fragmented (sent as several packets instead of as one
Threshold	packet). A low Fragmentation Threshold can help when communication is poor or when there
	is a significant interference.
	The default is 2346. The value can be 256 to 2346 bytes.

Enable Short Preamble Short preamble can improve throughput when the SBG1000 access point and associated clients operate at 2, 5.5, or 11 Mbps. If you enable short preamble, be sure all wireless clients also support short preamble. Short preamble is an optional IEEE 802.11b feature that is useful if maximum throughput is important and interoperability with legacy IEEE 802.11b equipment is not required. The default is Disabled.
