(-).
Ethernet Data rate
Specify the transmission rate of data.
IP Address
If you select “Static(Manual)”, you have to specify a static IP address, subnet mask, default gateway
and DNS server for your local area network which connects to the LAN port of DAP-3860. Make
sure the specified IP address is unique on your network in order to prevent IP conflict.
Dynamic(DHCP)
Enable “Dynamic“ to allow the DHCP server within your local area network to assign an IP address
automatically.
Spanning Tree Protocol (STP)
Chapter 3 Basic Settings
29
Spanning Tree Protocol is a link management protocol for RCP bridges which provides path
redundancy while preventing loops in a network. STP allows only one active path at a time between
the RCP bridges but establish the redundant link as a backup if the initial link fails.
STP Forward Delay
STP Forward Delay is the time spent in detecting and learning network tree topology state before
entering the forward state. Default time value is 1 sec. Select Normal if you would like to modify the
parameter (4-30 seconds).
Link Aggregation
Link Aggregation combines two physical network links into a single logical link for increased
bandwidth. Besides, it provides load balancing.
Basic Wireless Settings
Open “Radio” in “Wireless” as below and select “WLAN 0” or “WLAN 1” to make basic wireless
configuration on radio card 1 and 2.
Figure 23 Basic Wireless Settings
Mode
In a point to point environment where there are only two radios, Peer to Peer is recommended as it
works more efficiently.
Chapter 3 Basic Settings
30
Bridge (CSMA): The DAP-3860 connects to another wireless device within the same networking
program using CSMA protocol. CSMA ensures that only one node is transmitting on the network at any
one time. Under this mode, both PTP and PTMP are available. It is highly recommended to use this
mode when the distance between two nodes is less than 20km.
Bridge (TDMA): The DAP-3860 connects to another wireless device within the same networking
program using TDMA protocol. TDMA divides each cellular channel into multiple time slots to increase
the amount of data that can be carried; hence increase the throughput. Under this mode, only PTP is
available and is suggested to use when the distance between the two DAP-3860s is greater than
20km.
Wireless Band
The DAP-3860 can only communicate with wireless devices of 802.11a.
Channel/Frequency
Channel varies much as the available band differs from country to country. Select a proper operating
channel in the drop-down list according to your situation.
Data Rate
Usually “Best” is preferred. Under this rate, the DAP-3860 will automatically select the highest
available rate to transmit. In some cases, however, like where there is no great demand for speed, you
can have a relatively-low data rate for compromise of a long distance.
Band Width
Four levels are available: 20MHz and 40MHz. Among them, 40MHz can enhance the data rate more
effectively, but will take more bandwidth, thus cause possible interference.
WMM
WMM (Wi-Fi Multimedia) is a subset of 802.11e. It allows wireless communication to define a priority
limit on the basis of data type, thus those time-sensitive data, like video/audio data, may own a higher
priority than common one. To enable WMM, the wireless client should support it.
Super Mode
Super mode is an effective way to enhance performance. It can boost the transmission data rate up to
108Mbps. To enable Super Mode, the remote DAP-3860 should enable the function as well.
Chapter 3 Basic Settings

Chapter 4 Advanced Settings
Advanced Wireless Settings
Open “Radio” in “Wireless” and turn to “Advanced Parameters” at the bottom to make advanced wireless
settings.
Figure 24 Advanced Parameters
RTS Threshold
The DAP-3860 sends RTS (Request to Send) frames to certain receiving station and negotiates the
sending of a data frame. After receiving an RTS, that STA responds with a CTS (Clear to Send) frame
to acknowledge the right to start transmission. The setting range is 0-2346 in byte.
Fragmentation Length
Specify the maximum size in byte for a packet before data is fragmented into multiple packets.
Setting it too low may result in poor network performance. Leave it at its default of 2346 is
recommended.
Distance in Meters
To decrease the chances of data retransmission at long distance, DAP-3860 can auto adjust proper
ACK timeout value by specifying distance of the two nodes. Default distance is 10km. This will be
only usefully in CSMA mode.
Chapter 4 Advanced Settings
32
Note:
We strongly recommended you leave most advanced settings at their defaults except
Distance in Meters; any modification on them may negatively impact the performance of
your wireless network.
Chapter 4 Advanced Settings
33
Bridge Links
Open “Bridge Links Setup” in “Wireless”. Bridge Links allow establishing PTP or PTMP connectivity with
as most four remote wireless devices, this feature only available under Bridge (CSMA) mode. Select
“WLAN 0”, and input the MAC addresses of radio cards from remote unit respectively.
Figure 25 Bridge Links for CSMA
The other way to establish PTMP connectivity is to setup the same group id under “Radio” in “Wireless”.
This feature only available under Bridge (TDMA) mode and only devices with the same Group ID can
communicate.

Chapter 6 Troubleshooting
This chapter provides troubleshooting procedures for basic problems with the DAP-3860. For warranty
assistance, contact your service provider or distributor for the process.
Q 1. What if my DAP-3860 fails to connect to the remote one?
•
Ethernet Link: Check the availability of power to the bridge by observing the LED status on the
power injector or on top of the RJ-45 Jack of the unit.
-
Green: The DAP-3860 is connecting to the backhaul network.
-
Off: The DAP-3860 disconnects from the wired network, check whether the power cord and
Ethernet cables to the network and bridge are correctly connected.
•
Basic Configurations: Mismatched basic settings among bridges are the most common cause
of connectivity fail. If the bridge does not associate with a remote bridge, check whether in each
device are identical.
•
Security Settings: Remote bridges attempting to authenticate to your DAP-3860 must support
the same security options configured in your bridge, such as WEP and AES. If your bridge fails to
associate with others, check whether the security settings are the same as your bridge settings.
•
Antenna Alignment: If the methods above are all checked to be correct, you can observe and
verify antenna alignment with RSSI value.
Q 2. What if I would like to reset the unit to default settings?
You may restore factory default settings in “Configuration File” from “Administrator Settings”
Q 3. What if I would like to download and restore my configuration settings?
You may download by generating a configuration file or upload the settings you have backed up
previously in “Configuration File” from “Administrator Settings”.
Chapter 6 Troubleshooting
57
Q 4. What if I can not open the Web-based management interface?
Please check the followings:
•
Check whether the power supply is OK; Try to power on the unit again.
•
Check whether the IP address of PC is correct (in the same network segment as the unit);
•
Login the unit via other browser such as Firefox.
•
Hard reset the unit.
Q 5. What if the signal quality is poor or not so good?
•
Check whether there is obstacle between units. Obstacle may lead to poor signal.
•
Check the antenna height.
Place the unit in a high position can help to get a better
communication in long distance transmission.
•
Check the polarization direction of antenna. Keep the polarization direction of antennas on two
associating units the same; if not (one is horizontal, another is vertical), the signal quality may
reduce dramatically.
•
Check the antenna angle. Align the antenna to the remote one if using directional antenna. Big
angle shift may lead to poor signal.
•
Check the feeder length. Too long feeder may increase the signal loss and affect the unit
performance
