1. Introduction
This document is the user manual for the SMC WTK-Gproduct..
2. Quick Start
The default IP address of the WTK-Gis 192.168.2.25. The login is“admin” and password is“smcadmin”.
1.Connect the SMC WTK-Gto a PC using an ethernet cable.
2.Plug in the 5V power supply.
3.Make sure the PC has a IP address on the 192.168.2.xxx subnet, such as 192.168.2.100.
4.Open your web browser and navigate to 192.168.2.25.
5.Type“admin” for the login field and “smcadmin” for the password.
6.The default out-of-box operating mode is Access Point (AP) mode. To switch to Repeater, P2P,
PMP or Client mode, go to the Mode page and select the desired mode. Click Apply. The board will
reboot into the desired mode.
7.After the board reboots, go to the Mode page and click Setup. Configure the applicable properties
for that mode, such as security, SSID, channel, etc.
8.The SMC WTK-Gshould now be ready to use.
3. Operating Modes
3.1 Introduction to Operating Modes
3.1.1 Traveler’s AP Mode
The Access Point (AP) mode is by default the out-of-box operational mode. When the
user resets the system to the default manufacturing settings, the operational mode also
reverts to AP mode. In the AP mode, the system functions as a standard AP, where wireless
clients connected to the AP can then connect to other wireless clients or to the wired network.
For example, when traveling to a hotel that has high speed internet access, the user can
connect to the Internet through the AP which is connected to an ethernet cable in the room.

Note that the SMC WTK-GAP acts only as a layer 2 bridge and does not act as a
DHCP server. In other words, it does not supply dynamic IP addresses and instead relies
on the network to supply them.
Figure 1: AP Mode
Wireless Client
SMC WTK-GAP Mode Wireless Client

3.1.2 Repeater Mode
Repeater mode extends the range of a wireless network. Repeater nodes retransmit
the signal of an AP or wireless router to effectively extend the range of that AP or wireless
router. Wireless clients can associate with the repeater.
Figure2 shows the network with one repeater, and the repeater allowing wireless
clients to associate.
To configure the SMC WTK-Gas a Repeater, please ensure the following:
.•Enter the MAC address of the Parent AP or wireless router in the Remote AP MAC address
field in the SMC WTK-GRepeater.
•Enter the MAC address of the SMC WTK-G(Repeater mode) in the Repeater MAC adddress
field in the Parent AP or wireless router.
Figure 2: One Wireless Repeater Node

3.1.3 Point-to-Point (P2P) Mode
Two SMC WTK-Gdevices, each in Point-to-Point (P2P) mode, can establish a
wireless connection between two wired networks, as shown in Figure3. The two SMC
WTK-Gdevices operating in P2P mode do not allow client associations.
To configure the SMC WTK-Gdeivces to establish a P2P wireless bridge, please
ensure the following:
.• Enter the MAC address of SMC WTK-GP2P_2 device in the P2P MAC address field in the
SMC WTK-GP2P_1 device.
• Enter the MAC address of SMC WTK-GP2P_1 device in the P2P MAC address field in the
SMC WTK-GP2P_2 device.
Figure 3: P2P Wireless Bridge

3.1.4 Point-to-Multipoint (PMP) Mode
A SMC WTK-Gdevice operating in Point-to-Multipoint (PMP) mode can wirelessly
connect two or more wired networks, as shown in Figure4. The root SMC WTK-Gdevice
(LAN 1) operates in PMP mode, and the other SMC WTK-Gdevices (LAN 2, LAN 3) must
operate in P2P mode.
When operating in PMP mode, the SMC WTK-Gdevice does not allow client
associations. The user must enter the MAC addresses of each (up to six) SMC WTK-GP2P
device into the PMP system's table of Remote AP addresses.
Figure 4: PMP Wireless Bridge

3.1.5 Client Mode
When set to Client mode, the SMC WTK-Gdevice will associate to an AP within its
range in infrastructure mode, as shown in Figure5or join with another SMC WTK-Gdevice in
Client mode in an ad-hoc network, as shown in Figure6. The Client behaves like a normal
wireless client.

4. Wireless Security Support
The SMC WTK-Gwill support WEP encryption and WPA/PSK encryption as
shown in Table1.
Table 1: Wireless Security
Mode WEP WPA/PSK Comments
Access Point Yes Yes In AP mode, the WTK-Gacts like a regular AP. Supports
WEP and WPA/PSK.
Repeater Yes No (for The link between the Repeater and wireless clients will

releases will support WPA/PSK.
Point-to-Multipoint Yes No The link between WTK-Gdevices in P2P and/or PMP
(PMP) mode will support only WEP in the initial release. Future
releases will support WPA/PSK.
Client Yes Yes In Client mode, the WTK-Gacts like a regular wireless
client, so it will support WEP and WPA/PSK when
connecting with an AP in infrastructure mode or WEP
when connecting to an Ad-Hoc network.

5. Mode Selection
The first step in using the SMC WTK-Gis selecting the operating mode. The default operating mode is
the AP mode.
To view the device’s web page, go to 192.168.2.25 (default IP address of the device) in your web
browser. The default username is“admin” and the password is “smcadmin.”
To select a mode, click the Mode tab. Click the radio button next to the desired mode and click the Apply
button. The device will reboot in the selected mode. After the board reboots, click the Setup button to
begin configuring the device.
