1. Introduction

1.5.2 Dual AP Mode

In Dual AP mode, both wireless interface of A.DUO are set as AP and provide hotspot service on each interface. Radio1 is set to 11a mode while Radio2 is set to 11g/b Mode (changeable to 11a also). This mode is most useful for Dual Band Hotspot function such as in the hotels, shopping malls, or offices.

AirLive A.DUO User’s Manual

1. Introduction

1.5.3 WISP + AP Mode

In this mode, Radio1 (in 11a mode) acts as a client to connect with remote WISP Base Station. Radio2 (in 11g/b mode) works as an AP router to allow subscriber to share the WISP connection wirelessly. Using the A.DUO, WISP no longer requires 2 AP/CPE to provide wireless access in subscriber’s home or office.

1.5.4 Bridge + AP Mode

In this mode, Radio1 is working as Bridge mode in 5GHz while Radio is working as AP mode in 2.4Ghz or 5GHz (selectable0). This mode is useful for WISP backbone application where Radio 1 is used for connection to another Base Station and Radio2 is used for service to subscribers. This mode can also be used as repeater in indoor environment.

3.2 Prepare Your PC

The A.DUO can be managed remotely by a PC through either the wired or wireless network. The default IP address of the A.DUO is 192.168.1.1 with a subnet mask of 255.255.255.0. This means the IP address of the PC should be in the range of 192.168.1.2 to

192.168.1.254.

The default mode for A.DUO is “Dual Band Router” mode. In this mode, the A.DUO’s DHCP server is turned on; therefore, your PC can get IP automatically from A.DUO. You jus need to set your PC to “Obtain IP address automatically” on the TCP/IP setting. By default, Windows already do this so you do not need to change.

However, if you are using A.DUO in non-router modes (Dual AP, Dual Bridge, Bridge+AP, Cllient+AP). You need to set your IP mannuall. To prepare your PC for management with the A.DUO, please do the following:

1. Connect your PC directly to the LAN port on the DC Injector of A.DUO

2. Set your PC’s IP address manually to 192.168.1.100 (or other address in the same

subnet)

You are ready now to configure the A.DUO using your PC.

3.3 Management Interface

The A.DUO can be configured using one the management interfaces below:

3.3.1 Web Management (HTTP):

You can manage your A.DUO by simply typing its IP address in the web browser. Most functions of A.DUO can be accessed by web management interface. We recommend using this interface for initial configurations. To begin, simply enter A.DUO’s IP address (default is

192.168.1.1) on the web browser. The default user name is “admin”; default password is “airlive”.

3.3.2 Secured Web Management (HTTPS):

HTTPS is also using web browser for configuration. But all the data transactions are securely encrypted using SSL encryption. Therefore, it is a safe and easy way to manage your A.DUO. We highly recommend WISP and service provider to use HTTPS for management.

To begin, simply enter https://192.168.1.1 from your browser will pop up. Please click “Continue to this website” to login A.DUO.

For more information about Web Management and HTTPS, please make sure to read through “Intr oduction to Web Management” in this chapter, Chapter 4, and Chapter 5

3.3.3 Command Line Interface (Telnet):

A.DUO can be managed through the command line interface (CLI). It is possible to write a text script file, and then paste it into the CLI to execute several commands at once. However, Telnet does not encrypt its message. Therefore, it is not secure. The default Telnet management port is TCP port 23.

To use the CLI, please open the command line window. Then type “telnet 192.168.1.1” to start.

When asked for password, please enter “airlive”.

SSH is an encrypted Command Line Interface that allow user to send text commands through SSL encryption. Therefore, it provides the added advantage of security comparing to Telnet. As with Telnet, the SSH and SSH2 provide the possibility to write a text script and paste into the CLI interface for multiple command execution. It also makes configuration change across many A.DUOs easier. The default management port for SSH/SSH2 is TCP/UDP port 22.
