Fragmentation Threshold This value specifies the maximum size for a pack- et before data is fragmented into multiple packets. If you experience a high packet error rate, you may slightly increase the Fragmentation Threshold. Setting the Fragmentation Threshold too low may result in poor network per- formance. Only minor reduction of this value is recommended. In most cases, it should remain at its default value of 2346.
