ADVANCED WIRELESS SETTINGS

The Advanced Settings page includes additional parameters concerning the

wireless network and Wi-Fi Multimedia settings.

The following items are displayed on this page:

◆ Beacon Period — The rate at which beacon signals are transmitted

from the access point. The beacon signals allow wireless clients to

maintain contact with the access point. They may also carry power-

management information. (Range: 20-999 TUs)

◆ DTIM Period — The rate at which stations in sleep mode must wake

up to receive broadcast/multicast transmissions.

Known also as the Delivery Traffic Indication Map (DTIM) interval, it

indicates how often the MAC layer forwards broadcast/multicast traffic,

which is necessary to wake up stations that are using Power Save

mode. The value of one beacon indicates that the access point will save

all broadcast/multicast frames for the Basic Service Set (BSS) and

forward them after every beacon. Using smaller DTIM intervals delivers

broadcast/multicast frames in a more timely manner, causing stations

in Power Save mode to wake up more often and drain power faster.

Using higher DTIM values reduces the power used by stations in Power

Save mode, but delays the transmission of broadcast/multicast frames.

(Range: 1-255 beacons)

◆ Frag Threshold – Configures the minimum packet size that can be

fragmented when passing through the access point. Fragmentation of

the PDUs (Package Data Unit) can increase the reliability of

transmissions because it increases the probability of a successful

transmission due to smaller frame size. If there is significant

interference present, or collisions due to high network utilization, try

setting the fragment size to send smaller fragments. This will speed up

the retransmission of smaller frames. However, it is more efficient to

set the fragment size larger if very little or no interference is present

because it requires overhead to send multiple frames. (Range: 256-

2346 bytes)

◆ RTS Threshold — Sets the packet size threshold at which a Request to

Send (RTS) signal must be sent to a receiving station prior to the

sending station starting communications. The access point sends RTS
