Chapter 4 Configuration

Connect the R2 Extender to a Local Computer

If you are configuring the R2 Extender locally (without connecting its power injector to a wired
LAN), connect a PC to the power injector’s Ethernet port using a Category 5 Ethernet cable.

1. Assign a static IP address to your PC which is in the same network segment with the R2
Extender. As the default IP address of this unit is 192.168.1.1, you may choose from

192.168.1.2 to 192.168.1.254.

2. Test the link status between your PC and the R2 Extender. Start a command prompt and
execute a continuous ping command “ping 192.168.1. 1 –t”. If ping to the wirel ess bridge is
successful (as shown below), open Internet browser and enter the bridge’s IP address in
the address filed and press Enter.

How to Establish Wireless Bridge Mode

The R2 Extender supports four operating modes, which are Base Station, CPE, Peer-to-Peer
(CSMA) and Peer-to-Peer (TDMA). Normally, Wireless Bridge is the typical mode on this unit.
Here we will illustrate how to establish wireless bridge connectivity with R2 Extender.

Enter the user name (admin) and password (password) to login and make configurations.

Note:

Due to browser’s security trusted sites, 192.168.1.1 might not able to be opened.
You may choose to continue to the website.

Open “Basic Setup” in “System”, set the IP address of two R2 Extenders in the same

network segment. e.g. local R2 Extender as 192.168.1.1 and remote R2 Extender as

Chapter 5 Troubleshooting Page 14

192.168.1.2 and set the IP Subnet Mask on both as 255.255.255.0

Warning:

Each IP address is unique within a LAN, otherwise IP collision may occur!

Open “Radio” in “Wireless” and you will find the default operating mode is Peer-to-Peer

(CSMA). Select RF1(WLAN1) or RF2 (WLAN2) as Bridge to make the following
configuration. Here we take RF1 as an example. Se select Peer-to-Peer (CSMA)
operating mode and keep the Channel/Frequency and Bandwidth on both R2 Extenders
identical. Click “Apply” to save settings.

Chapter 5 Troubleshooting Page 15

Login the Web-based interface of remote R2 Extender, open “About” in “System” and

record the wireless MAC address of it, either WLAN 1 or WLAN 2 MAC Address.

Login the Web-based interface of local R2 Extender and open “Peer-to-Peer Setup” in

“Wireless”. Select “RF1” , input the WLAN1 or WLAN2 MAC address of the remote one to
“Remote MAC Address 1” field and click “Apply”;

Chapter 5 Troubleshooting Page 16

Warning:

The MAC address on the housing of R2 Extender is the ETH MAC address;

therefore it can not be used in Peer-to-Peer links.

The IP address of your PC should be in the same network segment to the one

of bridges.

Use ping to check whether the link between the two R2 Extender is OK.

R2 Extender B R2 Extender A

To get a better wireless connectivity, antenna alignment is strongly recommended after

both R2 Extenders are installed long distance apart.

Login the Web-based interface of the local R2 Extender and open “Peer-to-Peer Setup”

Chapter 5 Troubleshooting Page 17

in “Wireless”. Select RF1 and hit “Align Antenna” button, an antenna alignment tool will
popup. Specify the Target RSSI and click “Start” to begin the antenna alignment.

Fix the local antenna and adjust the remote antenna elevation and horizontal direction.

During the adjustment, observe “Current RSSI” in local R2 Extender. 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.
Congratulations! You have primarily completed configuration on R2 Extender and they can be
put into operation. For more advanced configurations, please refer to the User manual.

Chapter 5 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.

- Green: The R2 Extender is connecting to the backha ul 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
WP A (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”.
