Chapter 2: About
Operation Modes
This device provides operational applications with AP, Gateway and Client (Infrastructure) modes,
which are mutually exclusive.
This device is shipped with configuration that is functional right out of the box. If you want to change
the settings in order to perform more advanced configuration or even change the mode of operation,
you can MANUALLY switch to the mode you desired by the manufacturer as described in the
following sections.
Access Point Mode
When acting as an Access Point (AP), this device connects all the stations (PC/notebook with wireless
network adapter) to a wireless network. All stations can have the Internet access if only the Access
Point has the Internet connection.

5
Gateway Mode
The wireless connection will be set up from a point-to-point local LAN into a point-to-multipoint
WAN. This device connects all the stations (PC/notebook with wireless function) to a wireless network.
All stations can have the Internet access if only the device has the Internet connection.

If you cannot connect...
If the Wireless Portable Router does not respond, please check following:
•The Wireless Portable Router is properly installed, LAN connection is OK, and it
is already powered ON. You can test the connection by using the "Ping"
command:
•Please go to Start>Run…> Enter “cmd” command in the column to open
the MS-DOS window.
•Enter the command: ping 192.168.1.254
If no response is received, either the connection is not working, or your PC's IP
address is not compatible with the Wireless Portable Router's IP Address. (See
next item.)
•If your PC is using a fixed IP address, its IP address must be within the range
192.168.1.1. to 192.168.1.253 to be compatible with the Wireless Portable Router's
default IP Address of 192.168.1.254. Also, the Network Mask must be set to
255.255.255.0. See Chapter 4 - PC Configuration for details on checking your PC's
TCP/IP settings.
•Ensure that your PC and the Wireless Portable Router are on the same network
segment. (If you don't have a router, this must be the case.)
•Ensure you are using the wired LAN interface. The Wireless interface can only be
used if its configuration matches your PC's wireless settings.
