Wireless-N Router
Linksys E1000 Chapter 3: Advanced Configuration
RTS Threshold Should you encounter inconsistent data
flow, only minor reduction of the default value, 2347, is
recommended. If a network packet is smaller than the
preset Request to Send (RTS) threshold size, the RTS/CTS
(Clear to Send) mechanism will not be enabled. The Router
sends 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 CTS frame
to acknowledge the right to begin transmission. The RTS
Threshold value should remain at its default value of 2347
