Advanced Page
This page handles advanced routing and wireless settings. The Advanced options page allows you to
manage advanced settings that influence the device performance and behavior. The advanced wireless
settings are for more technically advanced users who have sufficient knowledge about wireless LAN
technology. These settings should not be changed unless you know what effect the changes will have on
your device.

Advanced Wireless Settings

RTS Threshold: determines the packet size of a transmission and, through the use of an access point, helps
control traffic flow. The valid range is 0-2347bytes, or “off”. The default value is 2347 which means RTS is
disabled.
RTS/CTS (Request to Send / Clear to Send) is the mechanism used by the 802.11 wireless networking
protocol to reduce frame collisions introduced by the hidden terminal problem. RTS/CTS packet size
threshold is 0-2347 octets. If the packet size the node wants to transmit is larger than the threshold, the
RTS/CTS handshake is triggered. If the packet size is equal to or less than threshold the data frame is sent
immediately
Fragmentation Threshold: specifies the maximum size of a packet before data is fragmented into multiple
packets. The valid range is 256-2346 bytes, or the word “off”. Setting the Fragmentation Threshold too low
may result in poor network performance. Only minor modifications of this value are recommended, the
default setting of 2346 should remain in most cases.
The use of fragmentation can increase the reliability of frame transmissions. Because sending smaller
frames, collisions are much less likely to occur. The fragment size should typically be set between 256 and
2,048 bytes.
Aggregation: Allows a much larger "burst" of frame data to be sent. Note: Aggregation will disable
multicast traffic from crossing the radio link and may change the order in which packets are sent across the
link (not recommended for controls networks) so it should only be used with a protocol that supports
reordering of packets like TCP.
Enable Extra Reporting: Un-check this if you are having problems with Intel Chipset wireless cards
Enable Client Isolation: This option allows packets only to be sent from the router to the CPE. In other
words, CPE's on the same network as the AP will not be able to see each other.
