Chapter 6: Configuring the Wireless-G Access Point
The Wireless - Advanced Wireless Settings Tab
Wireless-G Access Point with Power Over Ethernet and Rangebooster
The Wireless - Advanced Wireless Settings Tab
This screen allows you to configure the advanced settings for the Access Point. Linksys recommends to let your
Access Point automatically adjust the parameters for maximum data throughput.
Advanced Settings
CTS Protection Mode
. CTS (Clear-To-Send) Protection Mode function boosts the Access Point’s ability to catch
all wireless transmissions, but will severely decrease performance. Keep the default setting,
Auto
, so the Access
Point can use this feature as needed, when the Wireless-G products are not able to transmit to the Access Point
in an environment with heavy 802.11b traffic. Select
Disabled
if you want to permanently disable this feature.
BSSBasicRateSet
. This setting is a series of rates that are advertised to other wireless devices as defined in
IEEE 802.11 specifications, so they know which data rates the Access Point can support. One of the rates is
picked from the list for transmitting control frames, broadcast/multicast frames, or ACK frames. To support both
802.11b & 802.11g devices, use the Default (
Mixed
mode) setting so that frames can be decoded by all devices.
To support 802.11g devices only, use the All (
G-only
mode) setting to achieve higher frame rates. For regular data
frames, the transmission rate is configured through the Tx Rate Limiting on the Wireless - VLAN & QoS tab.
Power Output
. You can adjust the output power of the Access Point to get the appropriate coverage for your
wireless network. Select the level you need for your environment. If you are not sure of which setting to choose,
then keep the default setting,
100%
.
Beacon Interval
.
This value indicates the frequency interval of the beacon. A beacon is a packet broadcast by
the Access Point to keep the network synchronized. A beacon includes the wireless networks service area, the
Access Point address, the Broadcast destination addresses, a time stamp, Delivery Traffic Indicator Maps, and
the Traffic Indicator Message (TIM). The default is
100
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
1
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
2347
. 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 2346. 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

to apply your changes, or click

to cancel your changes. Help information is available on the right side of the screen.
The Wireless - VLAN & QoS Tab
This screen allows you to configure the VLAN and QoS related settings for the Access Point.
VLAN
The following options are global VLAN settings for the Access Point.
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 1. 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.
VLAN Tag
. Set the tagging option for the default VLAN ID. This has to match your Switch's settings. The default is
untagged.
AP Management VLAN
. 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 1. 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.
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.
Figure 6-16: Wireless - VLAN & QoS
NOTE:
To use wireless security which requires
RADIUS server (802.1X) authentication, the VLAN
ID needs to be the same as AP management
VLAN ID. We will remove this restriction in future
releases.

QoS
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 under the Basic Wireless Settings tab. If an SSID has been disabled, the
options cannot be configured.
VLAN ID
. Select a number between 1 and 4094 to identify the VLAN. Multiple SSIDs can share the same VLAN
value.
Priority
. You can assign the default priority (802.1p COS bits) for packets coming in from each wireless network
by selecting a number from the drop-down menu. The higher the number, the higher the priority will be. The
default is 0.
Tx Rate Limiting
. 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 for Mixed or G-Only wireless mode, 11 Mbps for B-Only
mode.
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 priority queues for different types of traffic. It
automatically maps the incoming packets to the appropriate queues based on QoS settings (in the IP or layer 2
header). WMM provides the capability to prioritize wireless traffic in your environment. The default is Disabled
(unchecked).

The AP Mode Tab
Wireless-G Access Point with Power Over Ethernet and Rangebooster
The AP Mode Tab
On this screen you can change the Access Point’s mode of operation. In most cases, you can keep the default
setting -
Access Point
. You may wish to change the Access Point’s mode of operation if you want to use the
Access Point as a wireless repeater to extend the range of your wireless network. You may also wish to change
the Access Point’s mode of operation if you want to use the Access Point as a wireless bridge; for example, you
can use two Access Points in Wireless Bridge mode to connect two wired networks that are in two different
buildings.
AP Mode
The Access Point offers three modes of operation: Access Point, Wireless Repeater, and Wireless Bridge. For the
Repeater and Bridge modes, make sure the SSID, channel, and security settings are the same for the other
wireless access points/devices.
MAC Address
The MAC address of the Access Point is displayed here.
Access Point
. The Mode is set to Access Point by default. This connects your wireless PCs to a wired network. In
most cases, no change is necessary.
Allow wireless signal to be repeated by a repeater
. Select this option if you want to use another wireless
device to repeat the signal of this Access Point. You will need to enter the MAC address(es) of the repeating
device(s). Up to 3 repeaters can be used.
IMPORTANT:
For the AP Client and Wireless Bridge modes, the remote access point must be a
second Linksys Wireless-G Access Point. For the Wireless Repeater mode, the remote wireless
bridge must be a second Linksys Wireless-G Access Point or Wireless-G Router.
