Turn UPnP On: UPnP can be enabled or disabled for automatic device configuration. The default 
setting for UPnP is enabled. If disabled, the router will not allow any device to automatically 
control the resources, such as port forwarding (mapping), of the router. 
Advertisement Period: The Advertisement Period is how often the router will broadcast its UPnP 
information. This value can range from 1 to 1440 minutes. The default period is 30 minutes. 
Shorter durations will ensure that control points have current device status at the expense of 
additional network traffic. Longer durations may compromise the freshness of the device status but 
can significantly reduce network traffic.
Advertisement Time To Live: The time to live for the advertisement is measured in hops (steps) 
for each UPnP packet sent. The time to live hop count is the number of steps a broadcast packet is 
allowed to propagate for each UPnP advertisement before it disappears. The number of hops can 
range from 1 to 255. The default value for the advertisement time to live is 4 hops, which should 
be fine for most home networks. If you notice that some devices are not being updated or reached 
correctly, then it may be necessary to increase this value a little.
UPnP Portmap Table: The UPnP Portmap Table displays the IP address of each UPnP device that 
is currently accessing the router and which ports (Internal and External) that device has opened. 
The UPnP Portmap Table also displays what type of port is opened and if that port is still active for 
each IP address. 
Advanced Wireless Settings 
Note: Incorrectly changing these settings can prevent the wireless functions from working. 
RTS Threshold 
Request to Send Threshold. The packet size that is used to determine if it should use the 
CSMA/CD (Carrier Sense Multiple Access with Collision Detection) mechanism or the 
CSMA/CA define the mechanism for packet transmission. With the CSMA/CD transmission 
mechanism, the transmitting station sends out the actual packet as soon as it has waited for the 
silence period. With the CSMA/CA transmission mechanism, the transmitting station sends 
out an RTS packet to the receiving station, and waits for the receiving station to send back a 
CTS (Clear to Send) packet before sending the actual packet data. 
Fragmentation Length 
This is the maximum packet size used for fragmentation. Packets larger than the size 
programmed in this field will be fragmented. The Fragment Threshold value must be larger 
than the RTS Threshold value.
