Wireless-G Access Point
The Status Tab
The
Status
tab displays the Access Point’s current status.
Firmware Version
. This is the version of the Access Point’s current firmware.
AP Name
. This is the Access Point name specified on the Basic Setup screen.
MAC Address
. This is the Access Point’s MAC Address, as seen by your ISP.
Configuration Type
. This displays how the Access Point is assigned an IP address, either
Automatic
Configuration - DHCP
, if assigned by DHCP server, or
Static IP Address
and its IP Address and Subnet Mask, if
assigned by Static IP Address server.
IP Address
. This shows the Access Point’s IP Address, as it appears on your local, Ethernet network.
Subnet Mask
. When the Access Point is using a Subnet Mask, it is shown here.
MAC Address
. The MAC Address of the LAN interface is displayed here.
SSID
. The unique name shared among all points in your wireless network is displayed here.
Mode
. The Access Point’s mode is displayed here.
Channel
. The wireless channel shared by all wireless devices connected to this Access Point is displayed here.
Wireless Security
. The encryption method you chose in the Setup Wizard or changed from the Setup tab of this
Web-based Utility is displayed here.
Send
and
Receive
. The Send and Receive fields display the number of successful or dropped packets that have
been sent or received. Some packet loss is normal in wireless networking.
To update the status information, click the

Filters
Wireless access can be filtered by using the MAC addresses of the wireless devices transmitting within your
network’s radius.
Wireless MAC Filter
. To filter wireless users by MAC Address, either permitting or blocking access, click
Enable
. If you do not wish to filter users by MAC Address, select
Disable
.
Prevent
. Clicking this button will block wireless access by MAC Address.
Permit Only
. Clicking this button will allow wireless access by MAC Address.
Edit MAC Address Filter List
. Clicking this button will open the MAC Address Filter List. On this screen, you can
list users, by MAC Address, to whom you wish to provide or block access. For easy reference, click the
Wireless
Client MAC List
button to display a list of network users by MAC Address.
Change these settings as described here and click the

Advanced Wireless
Before making any changes to the Wireless tab, please check your wireless settings on other systems, as these
changes will alter the effectiveness of the Access Point. In most cases, these settings do not need to be changed.
Authentication Type.
The default is set to
Auto
, where it auto-detects for Shared Key or Open System.
Shared
Key
is when both the sender and the recipient share a WEP key for authentication.
Open Key
is when the sender
and the recipient do not share a WEP key for authentication. All points on your network must use the same
authentication type.
Transmission Rates.
The default setting is
Auto
. The range is from 1 to 54Mbps. The rate of data transmission
should be set depending on the speed of your wireless network. You can select from a range of transmission
speeds, or you can keep the default setting, Auto, to have the Access Point automatically use the fastest possible
data rate and enable the Auto-Fallback feature. Auto-Fallback will negotiate the best possible connection speed
between the Access Point and a wireless client.
CTS Protection Mode
. CTS (Clear-To-Send) Protection Mode should remain disabled unless you are having
severe problems with your Wireless-G products not being able to transmit to the Access Point in an environment
with heavy 802.11b traffic. This function boosts the Access Point’s ability to catch all Wireless-G transmissions
but will severely decrease performance.
Basic Rate
. The Basic Rate setting is not actually one rate of transmission but a series of rates, advertising to the
other wireless devices in your network at what rates the Access Point can transmit. At the
Default
setting, the
Access Point will advertise that it will automatically select the best rate for transmission. Other options of rates to
advertise are
1-2Mbps
, for use with older wireless technology, and
All
, when you wish to make all rates
advertised. The Basic Rate is not the rate transmitted; that is the Transmission Rate.
Antenna Selection.
This selection is for choosing which antenna transmits data, left or right. By default, the
Diversity
antenna selection, used to increase reception, is chosen.
Frame Burst
. Enabling this option should provide your network with greater performance, depending on the
manufacturer of your wireless products. If you are not sure how to use this option, keep the default,
Off
.
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 LAN service area, the AP
address, the Broadcast destination addresses, a time stamp, Delivery Traffic Indicator Maps, and the Traffic
Indicator Message (TIM).
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
2,346
. Should you encounter inconsistent data flow, only minor modifications are recommended.

Wireless-G Access Point
Fragmentation Length
.
This specifies the maximum size a data packet will be before splitting and creating a
new packet and should remain at its default setting of
2,346
. A smaller setting means smaller packets, which
will create more packets for each transmission. If you have decreased this value and experience high packet
error rates, you can increase it again, but it will likely decrease overall network performance. Only minor
modifications of this value are recommended.
DTIM Interval
. This value indicates how often the Access Point sends out a Delivery Traffic Indication Message.
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.

SNMP
The SNMP screen allows you to customize the Simple Network Management Protocol (SNMP) settings. SNMP is a
popular network monitoring and management protocol.
The Identification settings let you designate the Contact, Device Name, and Location information for the Access
Point. The SNMP Community settings allow names to be assigned to any SNMP communities that have been set
up in the network. You can define two different SNMP communities, with the default names being Public and
Private.
SNMP
. To enable the SNMP support feature, select Enable. Otherwise, select Disable.
Identification
. In the Contact field, enter contact information for the Access Point. In the Device Name field, enter
the name of the Access Point. In the Location field, specify the area or location where the Access Point resides.
SNMP Community
. You may change the name from its default, Public. Enter a new name in the Public field.
Then configure the community's access as either Read-Only or Read-Write.You may change the name from its
default, Private. Enter a new name in the Private field. Then configure the community's access as either Read-
Only or Read-Write.
