Overview
The TEW-212APBO is a standalone wireless client, which provides IP
routing functionality between a Local Area Network (LAN) and a Wide
Area Network (WAN). It uses an Ethernet interface to connect to LAN, and
wireless 802.11b-based interface to connect to a Wireless Networking
System, which provides miscellaneous WAN access.
Wireless Networking System
TEW-212APBO is part of the Wireless Internet Service Provision System. It
provides access for locally connected computers to WAN, such as the
Internet. In Figure 1 shown below, the client devices are connected to the
access points (please refer to TEW-212APBO specification).

Features
TEW-212APBO is based on indoor-outdoor architecture. An outdoor unit
with 2.4 GHz antennas is placed on the mast or roof of construction
elements. It is connected to the indoor unit via a UTP cable. An individual
computer or an entire local network can gain access to the Internet by simply
connecting the TEW-212APBO indoor unit to the switch/hub. TEW-
212APBO is a full featured IP router with extensive firewall capabilities and
a user-friendly web interface.

5 Operating Modes
The TEW-212APBO supports 5 different kinds of operating modes: AP-
Router, AP Bridge, Station Bridge and Station Router.
AP-Router Mode
In this mode, the TEW-212APBO wireless unit plays the roles of the
wireless network Access point and a router.
Figure 2: AP-Router mode
4

AP Mode
In this mode, TEW-212APBO acts as conventional wireless Access
point. The routing function is disabled. Local Network Area is
automatically set up to Wireless.
Figure 3: AP mode
5

Bridge Mode
When operating in this mode, one TEW-212APBO device can
connect with another TEW-212APBO device and form wireless
“bridge” interconnecting two or more local networks. Note that all
these devices must work in the same frequency channel and must have
the same SSID string. Please also note that wireless “bridge” DOES
NOT retransmits packets.
Figure 4: Bridge mode
6

Note: The following operational modes need to be configured, refer to
upgrade page for more information.
Station – Router mode
In this mode, TEW-212APBO wireless interface works as wireless
network client (connects to the Access point). Router part is active.
It must be defined which interface will be dedicated to the Local Area
Network LAN, and which to the External Network. Routing is
done by forwarding packets to the default gateway, which is set up
to External Network, so it is mandatory to define Local Network
Area interface.
7

Client-Bridge mode
In this mode, TEW-212APBO acts as wireless card (associates to the
access point)

Starting Up
To setup TEW-212APBO for the first time can be performed
through a web browser on a computer connected to the local
network. The administrator can use one of standard browsers
available (e.g., Netscape Navigator, or Microsoft Internet Explorer
versions 4.0 or later). Once the setup process is completed, TEW-
212APBO can be managed from any computer on the network that
has a web browser.
The steps to setup TEW-212APBO using a web browser are listed
below:
1. Launch a standard web browser on a computer connected to the
network.
2. Enter the TEW-212APBO IP address given to you from the ISP
into the URL field of your web browser (the default setting is
192.168.2.2). TEW-212APBO provides SSL (Secure Sockets
Layer) feature, so use https://192.168.2.2 to connect.

If local network settings were configured correctly, then a login
screen should appear:
Input the username (the default username is “root”) and correct password
(the default password is “pass”) and click the “OK” button to pass the
security control screen. Once the correct username and password
combination is entered, a TEW-212APBO welcome screen should appear as
below:

The Device Status page is divided into to four parts:
System Status table - This table shows TEW-212APBO software version,
system uptime (after last reboot), average load, memory usage and
radio signal strength (RSSI).
System service and interfaces status is shown in “Service/Interface
Status” table - This table shows wireless interface and system services
state. Possible values in this table can be Enabled/Disabled for
appropriate interface/service state.
Network status is shown in the “Network Status” table - This table
shows operating mode of the device, which can be “Router” for AP-
Router mode, “AP” – for access point mode and “Bridge” for bridge
mode.
Network statistics are shown in separate table - This table contains
statistics for both interfaces of the TEW-212APBO – wired and
wireless. The wired interface is called LAN, and the wireless interface
is called WLAN. Each column corresponds to the statistics value of the
interfaces:
TxData – amount of data transferred
TxErrors – amount of transmit errors
RxData – amount of data received
RxErrors – amount of receive errors
Collisions – amount of network collisions

Network Configuration Settings page
Router Mode
In Router mode, LAN (Local Area Network) and WAN (Wide Area
Network – For TEW-212APBO, this can be the enterprise networks on the
Internet) configurations can be modified using the LAN Settings and the
WAN Settings tables shown as followed:
Figure 9: Network Configuration Settings page -1 (Router mode)
17

WAN settings must be set up according to the information provided by the
ISP. There is no such restriction on LAN settings. WAN access can be
disabled to restrict LAN users access to this network.
The masquerade setting enables the users to use the NAT (Network Address
Translation) feature of TEW-212APBO. When this option is enabled, TEW-
212APBO “hides” LAN addresses to the “external world”. Access to the
services, such as web services, provided by servers in the LAN, can be
achieved by using the port forwarding feature.
LHint:Use known private IP addresses for the local network, because if
you use public addresses, you will not be able to connect to WAN. It is
recommended to use IANA (Internet Assigned Numbers Authority) reserved
private address space (10.0.0.0/8, 172.16.0.0/12 and 192.168.0.0/16) .
AP Mode
In AP and Bridge mode, TEW-212APBO does not require an active WAN
(Wide Area Network) interface, so the “WAN Interface Settings” table is not
displayed.
