Operating Mode
Four operating modes are available on the R2 Extender. In a point to point environment where there
are only two radios, Peer-to-Peer is recommended as it works more efficiently.
Base Station
: The R2 Extender connects directly to the main Ethernet LAN and receives
connectivity from other wireless devices.
CPE
: The R2 Extender connects to a remote LAN and the Base Station in it.
Peer-to-Peer (CSMA)
: The R2 Extender 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.
Peer-to-Peer (TDMA)
: The R2 Extender 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 R2
Extender is greater than 20KM.
Base Station ID (SSID)
For Base Station mode, it requires SSID for CPU clients to associate with. This wireless network
name is shared among all associated devices in your wireless network. Keep it identical on all those
devices. Note that the SSID is case-sensitive and can not exceed 32 characters.
Wireless Mode
The R2 Extender 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. To avoid adjacent channel interference, it
is highly suggested to set separate of the 2 RF links as far as possible.
Transmit Rate
Usually “Best” is preferred. Under this rate, the R2 Extender will automatically select the highest
available rate to transmit. In some cases, however, like where there is no great demand for speed,
Chapter 3 Basic Settings Page 33
you can have a relatively-low transmit rate for compromise of a long distance.
Output Power
Specify the signal transmission power. The higher the output power is, the wider the signal can cover,
but the power consumption will be greater accordingly then. Usually “100%” is preferred.
Band Width
Four levels are available: 5MHz, 10MHz, 20MHz and 40MHz. Among them, 40MHz can enhance
the data rate more effectively, but will take more bandwidth, thus cause possible interference.
TDM Coordination
Stands for “Time-Division Multiplexing technique”, this resource reservation control mechanisms can
avoid packet collisions and send the packets much more efficiently allowing for higher effective
throughput rates.
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. R2 Extender provides you with three kinds of Super mode, which are Fast Frame,
Burst and Compression. To enable Super Mode, the remote R2 Extender should enable the
function as well. For more information you may refer to Super Mode in Chapter 4 Advance 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
CPE Download Speed
Specify fractional data rates (× 64Kbps). It allows the administrator to control the amount of data rate
each user is receiving. This is only available in CPE mode.
RTS Threshold
The R2 Extender 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.
Chapter 4 Advanced Settings Page 35
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.
Beacon Interval
Specify the frequency interval to broadcast packets. Enter a value between 20 and 1000.
Distance in Meters
To decrease the chances of data retransmission at long distance, R2 Extender 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.
TDM Coordination Time Slice
Specify the time slice of TDM Coordination. It allows a certain amount of time (in ms) that data will
transmit to each other before it moves to the next user. This is a repetitive cycle.
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.
Note:
Chapter 4 Advanced Settings Page 36
Peer-to-Peer Links
Open “Peer-to-Peer Setup” in “Wireless”. Peer-to-Peer Links allow establishing PTP or PTMP
connectivity with as most four remote wireless devices, this feature only available under Peer-to-Peer
(CSMA) mode and only devices with the same SSID can communicate. Select “RF1” or “RF2”, and input
the MAC addresses of radio cards from remote unit respectively.
Figure 25 Peer-to-Peer Links
Chapter 4 Advanced Settings Page 37
Antenna Alignment Tool
Under Peer-to-Peer (CSMA) mode, Antenna Alignment Tool is available. This function helps to point in the
approximate direction of the remote R2 Extender antenna and assist user easily align the local antenna to
reach maximum signal strength.
Figure 26 Antenna Alignment Tool
To use Antenna Alignment Tool, follow the steps bellow:
Open “Peer-to-Peer Setup” and select “RF1” or “RF2”. By clicking “Align Antenna” button,
“Antenna Alignment Tool ” window will popup.
Set the target RSSI (e.g. -70dBm) and click “Start” button.
Wait about 5 seconds, the antenna alignment starts and performs alignment every one second.
Fix the local antenna and adjust the remote antenna elevation and horizontal direction. During the
adjustment, observe “Current RSSI” in local R2 Extender. The value will refresh every 1 second. Fix
the remote antenna when it reaches your expectation. Usually, RSSI between -60 and -70dBm
indicates rather good signal strength.
Adjust the local antenna after fixing the remote one. During the adjustment, observe “Current RSSI”
in the remote R2 Extender. Fix the local antenna when it reaches your expectation.
Chapter 4 Advanced Settings Page 38
When the antenna alignment tool starts, the R2 Extender will issue beep sound to indicate current
RSSI. Once the tool is closed the R2 Extender will stop beeping. Frequency of beep indicate the
following RSSI:
T able 3 RSSI-Beep Frequency
RSSI Beep Frequency
>-50 100 /sec
-50~-60 50 /sec
-60~-70 5 /sec
-70~-80 2 / sec
-80~-90 1 /sec
< -90 No beep sound
Link Test
Under Base Station, CPE or Peer-to-Peer (TDMA) mode when Antenna Alignment Tool is not available,
Link Test provides another option to check the signal strength towards the connecting device. Open “Link
Test” in “Wireless” as below, and click “Refresh” to view the current signal strength of wireless
connectivity. The table will be updated every 3 seconds. If the signal is not so good, align the antenna

Link Aggregation
Link Aggregation combines two physical network links into a single logical link for increased bandwidth.
With it enabled, users can increase the capacity and availability of the communications channel between
devices (both switches and end stations). Besides, link aggregation also provides load balancing.
Open “Basic” in “System”, Link Aggregation is as below:
Figure 28 Link Aggregation
Full Duplex Two Channels: Normally, the wireless module in R2 Extender receives and transmits
wireless packets concurrently; if check this box, it only transmits wireless packets on WLAN but stops
receiving. Thus the wireless performance could be enhanced further more.
Link aggregation takes effect only when both cards work on peer-to-peer mode!
Note:
Chapter 4 Advanced Settings Page 41
Super Mode
Super mode is an effective way to enhance the Wi-Fi performance; it can boost the transmission data rate.
R2 Extender provides you with three kinds of Super mode, which are Fast Frame, Burst and Compression.
Open “Radio” in “Wireless”, Super Mode is as below:
Figure 29 Super Mode
Fast Frame
By utilizing frame aggregation and timing modifications, it increases throughput via transmitting more
data per frame and removing inter-frame pauses.
Burst
By allowing more data frames per given period of time, it increases throughput via overhead
reduction.
Compression
By performing real-time hardware data compression, it increases throughput via using
pre-compressed frames with no impact on host processor.
Chapter 4 Advanced Settings Page 42
Only all the wireless devices share the same wireless connectivity support Super mode,

Chapter 6 Troubleshooting Page 62
Chapter 6 Troubleshooting
This chapter provides troubleshooting procedures for basic problems with the R2 Extender.
Q 1. What if my R2 Extender 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 R2 Extender is connecting to the backhaul network.
- Off: The R2 Extender 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 R2 Extender must support
the same security options configured in your bridge, such as WEP and WPA (2)-PSK. 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 “Backup/Restore Settings” from “Management”
Q 3. What if I would like to backup and restore my configuration settings?
You may do the backup by generating a configuration file or retrieve the settings you have backed up
previously in “Backup/Restore Settings” from “Management”.
Chapter 6 Troubleshooting Page 63
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
