In this page, this utility gives you more flexibility to manage the access point. You can change
advanced configurations, such as Beacon Interval, DTIM, Fragmentation Threshold, Preamble
Type and RTS threshold.
Item
Beacon Interval
DTIM
Description
Beacons are packets sent by an Access Point to synchronize a
wireless network. The value of beacon interval is depending on the
environment where the AP is operating. Specify a Beacon interval
value between 1 and 1000(units: ms). The default value is set to
100 milliseconds, i.e., ten beacons per second.
Enter a value between 1 and 255 for the Delivery Traffic Indication
Message (DTIM). A DTIM is a countdown informing clients of the
next window for listening to broadcast and multicast messages.
When the Access Point has buffered broadcast or multicast
messages for associated clients, it sends the next DTIM with a
DTIM Interval value. AP clients hear the beacons and awaken to
receive the broadcast and multicast messages. The default value
for DTIM interval is set to 2.
This value should remain at its default setting of 2346. If you
Fragmentation
experience a high packet error rate, you may slightly increase your
Threshold
"Fragmentation" value within the value range of 256 to 2346.
Setting the Fragmentation value too low may result in poor
performance.
The Preamble Type defines the length of the CRC (Cyclic
Preamble Type
Redundancy Check) block for communication between the Access
Point and roaming wireless adapters. Make sure to select the
appropriate preamble type and click the Apply button. Note: High
network traffic areas should use the shorter preamble type. The
default value for preamble length is set to long. The Short
Preamble option improves throughput performance. The default
setting is Long.
The RTS threshold is the packet size at which packet transmission
RTS Threshold
is governed by the RTS/CTS transaction. Each station can have a
different RTS threshold. If you encounter inconsistent data flow,
only minor modifications to the value range between 256 and 2347
are recommended. The default value for RTS Threshold is set to
2347.

Troubleshooting
1. Revert the access point to Factory Default settings
You may follow the following steps to hard-reset the access point.
Reset Button
Locate the Reset button on the back of the access point.
Use a thin metal object, such as a paper clip or a pen point to press and hold the Reset
button for about 5 seconds and then release.
After the access point reboots (this may take a few moments) it will be reset to the
factory Default settings.
2. The computer used to configure the access point cannot access the Web Configuration
Page.
Check that the LAN LED on the access point is ON. If the LED is not ON, check that
the cable for the Ethernet connection is securely inserted and the power cable is
plugged into the power jack securely.
Check that the Ethernet card is working properly. Please check that the driver for the
network card is installed properly and check that the drivers are loaded properly.
Pleaser refer to the below point 3.
Check that the IP Address of the Ethernet card is in the same range and subnet as the
access point. Please refer to section 2 of Chapter 2: Configuring the Ethernet Adapter.
Verify that if you correctly type the Username and Password.
Note: The default IP address of the Access Point is 192.168.0.10 so the IP address for the
Ethernet Adapter must follow the 192.168.0.x IP address format and the IP should not be the
same IP address assigned to any other devices in the network. (Do not use these reserved
IP addresses: 192.168.0.1 and 192.168.0.10.)
Do a Ping test to make sure that the access point is responding. In the example, from
Windows Start menu -> Run>Type Command>Type ping 192.168.0.20. A successful
ping will show four replies.
3. Verify that the driver for the Ethernet card has installed successful
If you want to check that the driver’s installation is successful or not, follow the next steps. Your
Ethernet card model may differ from this example but the verification procedure is the same.
Right-click mouse button on the My Computer icon on your Windows desktop, and
highlight Properties from the pop-up menu.
The System Properties screen will be pop-up. Under Hardware tab, click Device
Manager….
After clicking Device Manager…, the following screen will be shown. Click on the +
symbol in front of “Network adapters” and see if an item labeled Wireless 802.11b
CardBus Adapter (34B1) is visible. If you don’t see the item below the network
adapter icon but a”?” or “!” symbol is displayed, it means that the driver installation was
unsuccessful. Highlight “Wireless 802.11b CardBus Adapter (34B1)”, right-click
mouse button and select “Properties”.
Click the General tab, if the Device Status field reports that “This device is working
properly”, it means that the driver has been installed successfully.
4. The computers with the wireless Ethernet cards installed can’t connect to the network
through the access point.
Make sure that each wireless client is configured to connect to the SSID of the AP. The
default SSID of the AP is MWL-27.
Make sure that each wireless client is configured to the same encryption setting with
the AP.
