WAN
The RJ-45 socket allows WAN connection through a Category 5 cable.
Support auto-sensing on 10/100M speed and half/ full duplex; comply
with IEEE 802.3/ 802.3u respectively.
LAN
The RJ-45 sockets allow LAN connection through Category 5 cables.
Support auto-sensing on 10/100M speed and half/ full duplex; comply
with IEEE 802.3/ 802.3u respectively.
WPS Push the WPS button implementation to reduce the network
configuration steps, and also easy to implement network security.
Reset Push continually the reset button 5 ~ 10 seconds to reset the
configuration parameters to factory defaults.

3. Installation
3.1 Hardware Installation
Step 1:
Place the WLAN Broadband Router to the best optimum transmission location. The best transmission
location for your WLAN Broadband Router is usually at the geographic center of your wireless
network, with line of sign to all of your mobile stations.
Step 2:
Connect the WLAN Broadband Router to your wired network. Connect the Ethernet WAN interface of
WLAN Broadband Router by category 5 Ethernet cable to your switch/ hub/ xDSL modem or cable
modem. A straight-through Ethernet cable with appropriate cable length is needed.
Step 3:
Plug in the DC power to the WLAN Broadband Router. Use only theAC/DC power adapter supplied
with the WLAN Broadband Router; it maybe occur damage by using a different type of power adapter.
The hardware installation finished.
3.2 Software Installation
There are no software drivers or utilities installation needed, but only the
configuration setting. Please refer to chapter 4 for software configuration.
Notice: It will take about 50 seconds to complete the boot up sequence after powered on the WLAN
Broadband Router; Power LED will be active, and after that the WLAN Activity LED will be flashing
to show the WLAN interface is enabled and working now.
