the router.
!
Changing parameters presented on this page may negatively affect your WLAN!
Figure 114. Additional settings of the WLAN.
The following fields are available on the page:
Parameter
Description
Beacon Period
The time interval (in milliseconds) between packets sent to
synchronize the wireless network.
RTS Threshold
The minimum size (in bites) of a packet for which an RTS frame is
transmitted.
Frag Threshold
The maximum size (in bites) of a non-fragmented packet. Larger
packets are fragmented (divided).
DTIM Period
The time period (in seconds) between sending a DTIM (a message
notifying on broadcast or multicast transmission) and data
transmission.
TX Power
The transmit power (in percentage terms) of the router.

Parameter
Description
BG Protection
The 802.11b and 802.11g protection function is used to minimize
collisions between devices of your wireless network.
Select a value from the drop-down list.
Auto
: The protection function is enabled and disabled automatically
depending on the state of the network (this value is recommended if
your wireless local area network consists of both 802.11b and
802.11g devices).
Always On
: The protection function is always enabled (this setting
can substantially lower the efficiency of your wireless network).
Always Off
: The protection function is always disabled.
TX Preamble
This parameter defines the length of the CRC block sent by the
router when communicating to wireless devices.
Select a value from the drop-down list.
Long Preamble
.
Short Preamble
(this value is recommended for networks with
high-volume traffic).
When you have configured the parameters, click the

WMM
On the
Wi-Fi / WMM
page, you can enable the Wi-Fi Multimedia function.
The WMM function implements the QoS features for Wi-Fi networks. It helps to improve the
quality of data transfer over Wi-Fi networks by prioritizing different types of traffic.
To enable the function, select the
WMM
checkbox and click the
Change
button.
Figure 115. The page for configuring the WMM function.
!
All needed settings for the WMM function are specified in the device's system. It is
recommended not to change the default values.
The WMM function allows assigning priorities for four Access Categories (AC):
•
AC_BK
(
Background
), low priority traffic (print jobs, file downloads, etc.).
•
AC_BE
(
Best Effort
), traffic from legacy devices or devices/applications that do not support
QoS.
•
AC_VI
(
Video
).
•
AC_VO
(
Voice
).
Parameters of the Access Categories are defined for both the router itself (in the
Parameters of
Access Point
section) and wireless devices connected to it (in the
Parameters of Station
section).

For every Access Category the following fields are available:
Parameter
Description
Aifsn
Arbitrary Inter-Frame Space Number
. This parameter influences
time delays for the relevant Access Category. The lower the value,
the higher is the Access Category priority.
CWMin/CWMax
Contention Window Minimum/Contention Window Maximum
. Both
fields influence time delays for the relevant Access Category. The
CWMax
field value should not be lower, than the
CWMin
field
value. The lower the difference between the
CWMax
field value
and the
CWMin
field value, the higher is the Access Category
priority.
Txop
Transmission Opportunity
. The higher the value, the higher is the
Access Category priority.
ACM
Admission Control Mandatory
.
If selected, prevents from using the relevant Access Category.
Ack
Acknowledgment
. Answering response requests while transmitting.
Displayed only in the
Parameters of Access Point
section.
If not selected, the router answers requests.
If selected, the router does not answer requests.
When you have configured the parameters, click the
