If you have a client PC that cannot run Internet applications properly from behind the DIR-301, then you can set the 
client up for unrestricted Internet access. It allows a computer to be exposed to the Internet. This feature is useful for 
gaming purposes. Enter the IP address of the internal computer that will be the DMZ host. Adding a client to the DMZ 
may expose your local network to a variety of security risks, so only use this option as a last resort.

Select  the  basic  transfer  rates  based  on  the  speed  of 
wireless  adapters  on  your  wireless  network.  It  is  strongly 
recommended to keep this setting to Auto.
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) 3 is the default setting. A DTIM is a countdown informing clients of the next window for 
listening to broadcast and multicast messages.
Select Short or Long Preamble. The Preamble defines the length of the CRC block (Cyclic Redundancy Check is a common 
technique for detecting data transmission errors) for communication between the wireless router and the roaming wireless 
network adapters. Auto is the default setting. Note: High network traffic areas should use the shorter preamble type.
CTS  (Clear To  Send)  is  a  function  used  to  minimize  collisions  among  wireless  devices  on  a  wireless  local  area  network 
(LAN).  CTS  will  make  sure  the  wireless  network  is  clear  before  a  wireless  client  attempts  to  send  wireless  data.  Enabling 
CTS will add overhead and may lower wireless through put. None: CTS is typically used in a pure 802.11g environment. If 
CTS is set to “None” in a mixed mode environment populated by 802.11b clients, wireless collisions may occur frequently.  
Always: CTS will always be used to make sure the wireless LAN is clear before sending data. Auto: CTS will monitor the 
wireless  network  and  automatically  decide  whether  to  implement  CTS  based  on  the  amount  of  traffic  and  collisions  that 
occurs on the wireless network.
WMM  is  QoS  (Quality  of  Service)  for  your  wireless  network.  Enable  this  option  to  improve  the  quality  of  video  and  voice 
applications for your wireless clients.

compatibility  with  networ king  equipment, 
software and peripherals.
Check  the  box  to  allow  the  WAN  port  to  be 
pinged.  Uncheck  the  box  and  the  DIR-301 
will  not  respond  to  pings.  Blocking  ping 
response  may  provide  some  extra  security 
from hackers. 
You may set the port speed of the WAN port 
to  10Mbps,  100Mbps,  or  10/100Mbps  Auto. 
Some older cable or DSL modems may require 
you to set the port speed to 10Mbps.
Gaming mode allows a form of pass-through 
for  certain  Internet  Games.  If  you  are  using 
Xbox, Playstation2 or a PC, make sure you are 
using  the  latest  firmware  and  Gaming  Mode 
is enabled. To utilize Gaming Mode, click the
