1. What is included
2. Installation Guide
2.1 How to connect
N900 comes with 2 network ports, one of which (beside the four LEDs) is intended to connect
local PC or switches and the other is intended to connect service provider to upper level router.
N900 can be powered using the DC power supply shipped with the box or using Power over
Ethernet (PoE) through WAN port. Using power supply is very straightforward. Just plug the jack
of the power supply into the power outlet on the wireless router. When you install N900
outdoor and there is no power outlet around, PoE is a good solution. The black adapter is PoE
power supply. It comes with 2 ports: POE and LAN. LAN is used to connect the router or Modem.
POE is used to connect to the WAN port of N900.

2.2 How to reset
In some cases, you may need to factory reset the system. For example, you forget your
password. After the system has boot up which takes about 1 minute, press the RESET button
which is located between the power supply plug and LEDs(see diagram above) for around 15
seconds before release it, the system will be reset after reboot with default configuration.
2.3 How to configure your PC for initial setup
The default IP address of the wireless router LAN port is 192.168.1.1. Since DHCP server on LAN
port is enabled by default. You can simply enable DHCP on the PC connecting to the LAN port of
the wireless router and the PC will get IP address automatically.

2.4 Login to the wireless router
The factory default IP address: 192.168.1.1
Default username: admin
Default password: admin
Open your browser and type the default IP into the address field, and enter the default user
credential as prompted, you should be able access the admin GUI of the wireless router.

3. Wireless Router Configuration
3.1 Wireless Router Operating Modes
LEGUANG N900 supports three operation modes:
Gateway Mode: In this mode, the device works as a router, connecting to Internet with
WAN port via ADSL/Cable Modem. Local PCs are connected to the router with LAN port
or WiFi. Network Address Translation (NAT) is enabled. Local PCs share the same IP to ISP
through WAN port. WAN port supports PPPOE, DHCP client or static IP. DHCP server on
LAN port is enabled by default to assign IP address to local PCs. With outdoor high gain
antenna, N900 can also connect the remote network together to share the Internet
connection. It is a very good solution for suburbs or rural area to access Internet. This is
the default mode of the equipment.
Bridge Mode: In this mode, all Ethernet ports and wireless interface are bridged
together so both network ports can be used to connect local PC. NAT function is
disabled. All the WAN related function and firewall are not supported. DHCP server on
LAN port can be enabled as needed. The device is essentially used as an access pint (AP).
Wireless ISP: In this mode, the device works as a wireless client and access point at the
same time. It acts as a wireless client to connect to ISP. It also acts as an access point to
connect local PCs with WiFi. All Ethernet ports are bridged together so both network
ports can be used to connect local PC. The NAT is enabled and all local PCs share the
same IP address to access ISP. The difference between Wireless ISP mode and Gateway
mode is that Gateway mode uses wired connection while Wireless ISP mode wireless
connection to access the service provider.

3.2 Gateway Mode configuration
1. Gateway mode is the default operating mode. If you are running a brand new system, you
don’t have to make any change to be in this mode. Otherwise you can switch to Gateway
mode on operation mode page as following:
2. Configure the LAN settings
In Gateway mode, wireless router can be used as a DHCP server to assign IP address to PCs
on local network, either wired or wireless. It is recommended to use the default setting and
enable DHCP to avoid IP address conflict.

3. Configure WAN settings
WAN is the port that connects to the service providers and it has to be configured to access
the Internet. Wireless router supports Dynamic IP, PPPoE, Static IP or PPTP. Pick the
appropriate the settings according to the service provider requirement. For most home
users, either PPPoE(ADSL) or dynamic IP (cable modem) should be used.
4. Wireless settings

At a minimum, you need to configure the SSID(network name), region, authentication
scheme and the key.
After you click apply, the system will take a few seconds to make the new settings take
effect:
In some cases, you may want to set up virtual access point to separate the wireless network.
N900 supports up to 2 virtual access points. Click “Virtual AP”, supply the SSID,
authentication scheme and key and then click “add”. After you click “Apply”, the system will
reboot with newly added virtual access points:

5. Now you should be able to see the wireless network you just configured from your PC or
tablet, smart phones, etc. Click the network and supply the password/key you just
configured to access the network.
3.3 Bridge Mode configuration
1. Switch to bridge mode
Since the default mode is not bridge mode, you need to manually change the operating
mode as following:
After you click “Apply”, the system will ask you to confirm whether to reboot the system to
make the change take effect.

Please OK and wait for the system to come back after reboot.
2. After the system switches to bridge mode, the GUI will be a bit different because some
settings like WAN and Firewall are not applicable in bridge mode.
3. Network settings
Only LAN port can be configured in bridge mode. DHCP is disabled by default, which works for
most cases. But you can enable it if desired:

2. Wireless client setting
In wireless ISP mode, the wireless router acts as a wireless client to the access point of the
service provider. Click “Connect Setting” that leads to the connection setting page where all
the wireless client related settings are configured. Click “ScanAP” and select the desired
access point from the list as below:

LEGUANG N900 Configuration Guide
ActForNet Technologies Copyright 2014 P a g e | 15
After you select the AP from the list, the Authentication field will be auto-populated
accordingly. You just need to type in the password that is supplied by your service provider.
After you click “Apply”, the system will reboot to make the change take effect. If the setting
is correct, the wireless router should connect to the service provider access point like
following:
3. WAN setting
In wireless ISP mode, the WAN port refers to the logic port the wireless client uses to connect to
the service provider. In other words, the WAN port of the wireless router is the only port visible
from the service provider. Please keep it in mind that wireless router has NAT enabled by

default and all the PCs on the local network will share the WAN IP address to access Internet. In
most case the default setting “dynamic IP” should work. But we can change it to static IP or
PPPoE as well if needed.
4. LAN settings
LAN port is intended to connect all local PCs. Usually you need to enable DHCP server to
automatically assign IP address to local PCs, like following:
5. Wireless settings
Settings in this section are used to control how local PCs, tablets or smarts phone connect to
the wireless router using WiFi. The setting is the same as Gateway mode or Bridge mode. At
a minimum, you need to configure the SSID(network name), region, authentication scheme
