Wireless Settings

Fragmentation Threshold -- This value should remain at its default setting of 2346. 

The range is 256-2346 bytes. The Fragmentation Threshold specifies the maximum 

size for a packet before data is fragmented into multiple packets. If you experience a 

high packet error rate, you may slightly increase the Fragmentation Threshold. 

Setting this value too low may result in poor network performance. Only minor 

modifications of this value are recommended.

RTS Threshold -- This value should remain at its default setting of 2347. The range is

0-2347 bytes. Should you encounter inconsistent data flow, only minor modifications are 

recommended. If a network packet is smaller than the packet RTS threshold size, the 

RTS/CTS mechanism will not be enabled. The Xcelerator IP sends Request of Send (RTS) 

frames to a particular receiving station and negotiates the sending of a data frame. After 

receiving an RTS, the wireless station responds with a Clear to Send (CTS) frame to 

acknowledge the right to begin transmission. 
DTIM Interval -- The default value is 3. This value, between 1 and 255 milliseconds, 

indicates the interval of the Delivery Traffic Indication Message (DTIM). A DTIM field is a 

countdown field informing clients of the next window for listening to broadcast and 

multicast messages. When the router has buffered broadcast or multicast for associated 

clients, it sends the next DTIM with a DTIM Interval value. Its clients hear the beacons 

and awaken to receive the broadcast and multicast message.
