If you have a client PC that cannot run Internet applications properly from behind the DIR-450, 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

(Demilitarized Zone) 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 2346. 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 mobile router and the roaming wireless

network adapters. Auto is the default setting. Note: High network trafﬁc areas should use the shorter preamble type.

WMM (Wi-Fi Multimedia) 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.
