Tick the checkbox to enable SPI. SPI (Stateful 
Packet  Inspection,  also  known  as  dynamic 
packet  filtering)  helps  to  prevent  cyber 
attacks by tracking more states per session. 
It validates that the traffic passing through the 
session conforms to the protocol.

from  behind  the  router,  you  can  expose 
one  computer  to  the  Internet  and  run  the 
application  on  that  computer.  Tick  the 
Enable DMZ Host checkbox if you want to 
add a computer to your DMZ. 
Note:  Placing  a  computer  in  the  DMZ  may 
expose that computer to a variety of security 
risks.  Use  of  this  option  is  only  recommended 
as a last resort.
Specify the IP address of the computer on the 
LAN that you want to have unrestricted Internet 
communication.  If  this  computer  obtains  its  IP 
address automatically using DHCP, be sure to 
make a static reservation on the  Basic >  DHCP 
page so that the IP address of the DMZ machine 
does not change.

Set the transmit power of the antennas.
Beacons are packets sent by an Access Point 
to  synchronize  a  wireless  network.  Specify 
a  value.  100  is  the  default  setting  and  is 
recommended. 
This value should remain at its default setting 
of 2432. If inconsistent data flow is a problem, 
only a minor modification should be made.
The fragmentation threshold, which is specified 
in  bytes,  determines  whether  packets  will  be 
fragmented. Packets exceeding the 2346 byte 
setting will be fragmented before transmission. 
2346 is the default setting. 
(Delivery Traffic Indication Message) 1 is the default setting. A DTIM is a countdown informing clients of the next window for 
listening to broadcast and multicast messages.
Select Short Preamble or Long Preamble .
Clear To Send (CTS) is a mechanism that wireless devices use when the surrounding environment is ‘dirty’ (i.e. many senders 
and receivers over the same wireless frequency).
When  the  CTS  Mode  is  set  to  Always  the  transmitting  device  will  need  to  send  out  an  RTS  (Request  To  Send),  and  the 
intended receiving device needs to send out a CTS (Clear To Send), bef\
ore the actual data can be sent.
Setting the CTS Mode to  Auto indicates that the router will decide whether or not the CTS mechanism should be used or 
not, depending on the current environment and data length.

some  extra  security  from  hackers.  Tick  the  box 
to allow the WAN port to be “pinged”.
You may set the port speed of the WAN/Internet 
port  to  10Mbps,  100Mbps,  or  auto.  Some  older
