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. 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.
