1 Overview
Thank you for choosing GETNET GR-124W.
GETNET GR-124W is fully compatible with 802.11g standard. Meanwhile, it is also
compatible with 802.11 standards and earlier 802.11 b standards. GETNET
GR-124W supports CCK and OFDM and its data rate is up to 54 Mbps. It is easy to
install and can be applied to AP and router access.
GR-124W provides 64-bit and 128-bit WEP encryption schemes, and WPA
encryption, associating with IEEE 802.1X authentication, which insures the security
of wireless communication.
Package List
Please check whether your package list includes the following items:
GR-124W x 1
Power adapter x 1
RJ 45 cable x 1

2 Hardware Description and Hardware Installation
2.1 Front Panel and LED Status
There are 8 LED indicators on the front panel of GR-124W. By observing their
status, you can judge whether the device runs normally.
The following table describes the LED indicators on the front panel.
LED
Indicator Color Status Description
Power Red On Power is on.
Green On The device runs normally.
- Off Power is off or the device is down.
WLAN Green On Radio switch is turned on.
Green Blink Data is being transmitted.
- Off Radio switch is shut off.
WAN Green On Connection succeeds.
Green Blink Data is being transmitted.

3
- Off No WAN connection.
LAN
1/2/3/4 Green On LAN connection succeeds.
Green Blink Data is being transmitted.
- Off No LAN connection.
2.2 Rear Panel and Interface Description
The following table describes the interfaces or the buttons on the rear panel:
Interface/Button Description
Reset Press the button for 3 seconds and
then release it. System restores the
factory default settings.
ON/OFF By pressing the button, the power is
on. Press the button again, and then
the power is off.
POWER Power socket, for connecting the
power adapter.
WAN WAN interface, for connecting WAN or
the uplink network devices.
LAN1~LAN4 LAN interface, for connecting hub,
switch, or computer on LAN.
Note:
Do not press the Reset button unless you want to clear the current settings. The
Reset button is in a small circular hole on the rear panel. If you want to restore the
default settings, please press the Reset button gently for 3 seconds with a fine
needle inserted into the hole and then release the button. The system reboots and
returns to the factory defaults.
Warning:

4
The power specification is 12V, 500 mA. If the power adapter does not match the
specification, it may damage the device.
2.3 Hardware Installation
2.3.1 System Requirements
Before installing the device, please make sure that the following items are ready.
At least one Ethernet RJ45 cable (10Base-T/100Base-T)
GR-124W x 1
A PC has been installed PCP/IP protocol and it can access the Internet.
2.3.2 Before You Begin
Before you install the device, please pay attention to the following items:
When connecting the device to the computer, hub, router or switch, the
Ethernet cable should be less than 100 meters.
Do not place this device on an unstable surface or support. Do not put this
device on the ground.
Keep the device clean. Avoid the device from direct sunshine. Avoid any
metal in the device.
Place the device in the center of the area, and try to optimize the wireless
coverage.
2.3.3 Connecting AP
Step 1 Connect one end of the RJ45 cable to the LAN interface of the GR-124W.
Step 2 Connect the other end of the RJ45 cable to your PC.
Step 3 Connect the power adapter to the power socket of the GR-124W.

2.4 Operation Range
The operation range of GR-124W depends on the actual environment. When the
device is placed in the house or in the office, the overall arrangements are different.
So the path and effect for the signal transmission are different. For example, the
outdoor straight transmission distance for some devices in the open air is up to 300
meters, and the indoor straight transmission distance is up to 100 meters.
2.5 Roaming
Suppose that several GR-124Ws run in the same network. Each GR-124W acts as
one BSS, and has its coverage. One wireless client terminal (e.g. notebook PC or
PDA) can realize roaming from one AP to another AP correctly. In that case, the
wireless client terminal can communicate with the other devices within the
GR-124Ws’ coverage.
In order to realize the wireless client roaming among different GR-124Ws, you need
to set the GR-124W properly. Do as follows:
Set the same SSID for different GR-124Ws.
The SSIDs of all the computers and PDAs should be consistent with that of
the GR-124Ws.
All the BSSs must use the same wireless channel.
If the encryption function is enabled, all the GR-124Ws should configure
the same encryption mode and the encryption key for establishing
connection.
GR-124W must keep the wireless signal cover the whole operation
environment and the wireless signal should be continuous. Please put the
GR-124Ws to the appropriate places for a better network coverage.
3 Network Configuration and Introduction to
Network Connection Modes
Web management tool allows you to configure GR-124W. The recommended
browser is Internet Explorer 5.0 version or above.
The following sections describe how to set the Internet connection, local Ethernet
connection, and wireless connection, and how to access the Web page of the
GR-124W.
