communicate with the AP. To execute the ping command, open the DOS window and ping the
IP address of the Wireless AP at the DOS prompt:
¾
For Windows 98/Me: Start -> Run. Type command and click OK.
¾
For Windows 2000/XP: Start -> Run. Type cmd and click OK.
At the DOS prompt, type the following command:
If the Command window returns something similar to the following:

Key 1 - Key 4
The WEP keys are used to encrypt data transmitted in the wireless network. Fill the text box by
following the rules: 64-bit WEP: input 10-digit Hex values (in the "A-F", "a-f" and "0-9" range)
or 5-digit ASCII character as the encryption keys. 128-bit WEP: input 26-digit Hex values (in
the "A-F", "a-f" and "0-9" range) or 13-digit ASCII characters as the encryption keys.

4.4.3. 802.1X Enterprise
IEEE 802.1x is an authentication protocol. Every user must use a valid account to login to this
Access Point before accessing the wireless LAN. The authentication is processed by a RADIUS
server. This mode also uses WEP to encrypt the data during communication.

For the WEP settings, please refer to section WEP
4.4.4. WPA Personal
Wi-Fi Protected Access (WPA) is an advanced security standard. You can use a pre-shared key
to authenticate wireless stations and encrypt data during communication. It uses TKIP or
CCMP (AES) to change the encryption key frequently. So the encryption key is not easy to be
broken by hackers. This can improve security very much.

Wireless Distribution System uses wireless media to communicate with other APs, like the
Ethernet does. To do this, you must set these APs in the same channel and set MAC address of
other APs which you want to communicate with in the table and then enable the WDS.

4.9. Advanced
You can set advanced wireless LAN parameters of this AP. The parameters include Fragment
Threshold, RTS Threshold, Beacon Interval, Preamble Type …… You should not change these
parameters unless you know what effect the changes will have on this AP.

Fragment Threshold
"Fragment Threshold" specifies the maximum size of packet during the fragmentation of data

to be transmitted.
¾
RTS Threshold
When the packet size is smaller the RTS threshold, the wireless AP will not use the RTS/CTS
mechanism to send this packet.
¾
Beacon Interval
The interval that this wireless AP broadcast a beacon, Beacon is used to synchronize the
wireless network.
¾
Transmit Rate
The “Transmit Rate” is the rate this access point uses to transmit data packets. The access point
will use the highest possible selected transmission rate to transmit the data packets.
¾
Preamble Type
The “Long Preamble” can provide better wireless LAN compatibility while the “Short
Preamble” can provide better wireless LAN performance
¾
802.11g Protection
This is also called CTS Protection. It is recommended to enable the protection mechanism. This
mechanism can decrease the rate of data collision between 802.11b and 802.11g wireless
stations. When the protection mode is enabled, the throughput of the AP will be a little lower
due to many of frame traffic should be transmitted.

5. FAQ
1. I cannot access the Web-based Configuration Utility from the Ethernet computer used
to configure the AP.
¾
Check that the LAN LED is on. If the LED is not on, verify that the cable for the LAN
connection is firmly connected.
¾
Check whether the computer resides on the same subnet with the AP’s LAN IP address.
¾
If the computer acts as a DHCP client, check whether the computer has been assigned an IP
address from the DHCP server. If not, you will need to renew the IP address.
¾
Use the ping command to ping the AP’s LAN IP address to verify the connection.
¾
Make sure your browser is not configured to use a proxy server.
¾
Check that the IP address you entered is correct. If the AP’s LAN IP address has been
changed, you should enter the reassigned IP address instead.
2. I forget Password (Reset the AP without Login)
¾
Plug out the power of the AP.
¾
Use a pencil to press and hold the default button on the back panel of the AP. Then plug in
the power of the AP.
¾
Press and hold the default button wait for a few seconds until the SYS LED indicator stays
green.
¾
Reboot the AP.
¾
After the above those steps, the manufacture’s parameters will be restored in the AP. The
default password is guest.
3. My wireless client cannot communicate with another Ethernet computer.
¾
Ensure the wireless adapter functions properly. You may open the Device Manager in
Windows to see if the adapter is properly installed.
¾
Make sure the wireless client uses the same SSID and security settings (if enabled) as the
Wireless AP
¾
Ensure that the wireless adapter’s TCP/IP settings are correct as required by your network
administrator.
¾
If you are using a 802.11b wireless adapter, and check that the 802.11G Mode item in
Wireless Basic Setting page, is not configured to use 802.11G Performance.
¾
Use the ping command to verify that the wireless client is able to communicate with the
AP’s LAN port and with the remote computer. If the wireless client can successfully ping the
- 43 -
Wireless AP User Manual
AP’ s LAN port but fails to ping the remote computer, then verify the TCP/IP settings of the
remote computer.
