Advanced Configuration

Wireless-G Access Point with Power Over Ethernet

Access Point address, the Broadcast destination addresses,
a time stamp, Delivery Traffic Indicator Maps, and the
Traffic Indicator Message (TIM). The default is 00 ms.

DTIM Interval

This value indicates how often the Access

Point sends out a Delivery Traffic Indication Message
(DTIM). Lower settings result in more efficient networking,
while preventing your PC from dropping into power-
saving sleep mode. Higher settings allow your PC to
enter sleep mode, thus saving power, but interferes with
wireless transmissions. The default is ms.

RTS Threshold

This setting determines how large a packet

can be before the Access Point coordinates transmission
and reception to ensure efficient communication. This
value should remain at its default setting of 4. If you
encounter inconsistent data flow, only minor modifications
are recommended.

Fragmentation Threshold

This specifies the maximum

size a data packet can be before splitting and creating a
new packet. It should remain at its default setting of 46.
A smaller setting means smaller packets, which will create
more packets for each transmission. If you experience
high packet error rates, you can decrease this value, but
it will likely decrease overall network performance. Only
minor modifications of this value are recommended.

Change these settings as described here and click Apply
to save your changes. Help information is available on the
right side of the screen.

Wireless > VLAN & QoS

This screen allows you to configure the VLAN and QoS
related settings for the Access Point.

Wireless > VLAN & QoS

VLAN

Select Enabled if you want to pass 802.1q VLAN

tagged traffic between the wired LAN and wireless LAN.
Your Access Point will map the VLAN tag (wired side) to
different SSIDs (wireless side) according to your specified
settings. Select Disabled and your Access Point will drop all

tagged traffic coming in from the wired LAN. The default
is Disabled.

Default VLAN ID

Enter the default VLAN ID number (1

- 4094), the default value is . The default VLAN number
should match with your Switch’s settings. For example,
the SRW2024 has Trunk port mode which set default VLAN
(PVID) to 1 untagged, while General port mode can set
PVID to any VLAN either tagged or untagged.

Default VLAN

Set the tagging option for the default

VLAN ID. This has to match your Switch’s settings. The
default is untagged.

Management VLAN ID

When the VLAN option is enabled,

the value entered (VLAN ID) in this field defines the VLAN
that connects to the Access Point. The default value is
. The VLAN should be accessible from the wired side in
order to use web-based utility. To access the web-based
utility from wireless side, the SSID needs to map to the
same VLAN ID. Remember to enable wireless web access
on the Administration > Management tab.

The following options are VLAN global settings for the
Access Point.

Default CoS (Priority)

Select Enabled if you want to

assign a default CoS value to each SSID. This option is
automatically enabled when the VLAN option is enabled.
The default is Disabled.

U-APSD (Unscheduled Automatic Power Save
Delivery)

This option is only available when WMM is

enabled on any of the SSIDs. Select Enabled if you want
client devices with U-APSD capability to take advantage
of the power save mode. The default is Disabled.

SSID Name

Displays the SSIDs defined on the Basic

Wireless Settings screen. If an SSID has been disabled, the
options cannot be configured.

VLAN ID

Select a VLAN ID (1 - 4094) for the SSID where

you want to map the traffic to on the wired side. The
wireless traffic will not carry VLAN information. Multiple
SSIDs can map to the same VLAN on the wired side.

Priority

You can assign the default priority (802.1p CoS

bits) for packets coming in from each wireless network by
selecting a value from the drop-down menu. The default
is Low.

Tx Rate Limitation

You can limit the maximum data

rate used in your network to save bandwidth and power
consumption on client devices. The actual data rate is
determined by the Auto-Fallback mechanism between
your Access Point and a client device. The default is 54
Mbps
.

WMM

Wi-Fi Multimedia is a QoS feature defined by the

WiFi Alliance before IEEE 802.11e was finalized. Now it is
part of IEEE 802.11e. When this is enabled, it provides four
