Chapter 2: About the Operation
Modes
This device provides three operational applications with Portable Router, 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 desire by the manufacturer as described in the following sections.
AP Mode
When acting as an access point, this device connects all the stations (PC/notebook with wireless network adapter) to a wired network. All stations can have the Internet access if only the Access Point has the Internet connection.
GW Mode
When GW mode is selected, the AP will enter the gateway mode. And the wireless connection will be set up from a point-to-point local LAN into a point-to-multipoint WAN.
3
Client Mode (Infrastructure)
If set to Client (Infrastructure) mode, this device can work like a wireless station when it’s connected to a computer so that the computer can send packets from wired end to wireless interface.

~ 2.4GHz (B+G): 802.11b supported rate and 802.11g supported rate. The
default is 2.4GHz (B+G) mode.
The SSID differentiates one WLAN from another; therefore, all access points and all devices attempting to connect to a specific WLAN must use the same SSID. It is case-sensitive and must not exceed 32 characters. A device will not be permitted to join the BSS unless it can provide the unique SSID. A SSID is also referred to as a network name because essentially it is a name that identifies a wireless network.
Allow user to set the channel manually or automatically. If set channel manually, just select the channel you want to specify. If “Auto” is selected, user can set the channel range to have the Wireless Portable Router automatically survey and choose the channel with best situation for communication. The number of channels supported depends on the region of this Access Point. All stations communicating with the Access Point must use the same channel.

Fragment Threshold: Fragmentation mechanism is used for improving the
efficiency when high traffic flows along in the wireless network. If your
802.11g Wireless LAN PC Card often transmit large files in wireless network, you can enter new Fragment Threshold value to split the packet. The value can be set from 256 to 2346. The default value is 2346. RTS Threshold: RTS Threshold is a mechanism implemented to prevent the “Hidden Node” problem. “Hidden Node” is a situation in which two stations are within range of the same Access Point, but are not within range of each other. Therefore, they are hidden nodes for each other. When a station starts data transmission with the Access Point, it might not notice that the other station is already using the wireless medium. When these two stations send data at the same time, they might collide when arriving simultaneously at the Access Point. The collision will most certainly result in a loss of messages for both stations. Thus, the RTS Threshold mechanism provides a solution to prevent data collisions. When you enable RTS Threshold on a suspect “hidden station”, this station and its Access Point will use a Request to Send (RTS). The station will send an RTS to the Access Point, informing that it is going to transmit the data. Upon receipt, the Access Point will respond with a CTS message to all station within its range to notify all other stations to defer transmission. It will also confirm the requestor station that the Access Point has reserved it for the time frame
9
of the requested transmission. If the “Hidden Node” problem is an issue, please specify the packet size. The RTS mechanism will be activated if the data size exceeds the value you set. The default value is 2346.
Warning: Enabling RTS Threshold will cause redundant network overhead that could negatively affect the throughput performance instead of providing a remedy.
The value can be set from 0 to 2346.
setting of 2346. Should you encounter inconsistent data flow, only minor modifications of this value are recommended.
This value should remain at its default
Beacon Interval: Beacon Interval is the amount of time between beacon transmissions. Before a station enters power save mode, the station needs the beacon interval to know when to wake up to receive the beacon (and learn whether there are buffered frames at the access point). Inactivity Time: By default, the unit adaptively selects the highest possible rate for transmission. For most networks the default setting is 30000 th at is the best choice. If obstacles or interference are present, the system will automatically fall back to a lower rate. Preamble Type: A preamble is a signal used in wireless environment to synchronize the transmitting timing including Synchronization and Start frame delimiter. If you want to change the Preamble type into Long or
Short, please select the mode you need. Broadcast SSID:
Enabled: This wireless AP will broadcast its SSID to stations.

Chapter 4: PC Configuration
Overview
For each PC, the following may need to be configured:
TCP/IP network settings
Internet Access configuration
Wireless configuration
Windows Clients
This section describes how to configure Windows clients for Internet access via the
Wireless Router.
The first step is to check the PC's TCP/IP settings.
The Wireless Router uses the TCP/IP network protocol for all functions, so it is essential
that the TCP/IP protocol be installed and configured on each PC.
TCP/IP Settings - Overview
If using default Wireless Router settings, and default Windows TCP/IP settings, no changes need to be made.
By default, the Wireless Router will act as a DHCP Server, automatically providing a
suitable IP Address (and related information) to each PC when the PC boots.
For all non-Server versions of Windows, the default TCP/IP setting is to act as a DHCP
client.
If using a Fixed (specified) IP address, the following changes are required:
The Gateway must be set to the IP address of the Wireless Router.
The DNS should be set to the address provided by your ISP.

Wireless Station Configuration
This section applies to all Wireless stations wishing to use the Wireless Router's Access
Point, regardless of the operating system that is used on the client.
To use the Wireless Portable Router in the Wireless Router, each Wireless Station must
have compatible settings, as follows:
Mode SSID (ESSID)
WEP
Note:
By default, the Wireless Router will allow both 802.11b and 802.11g connections.
The mode must be set to Infrastructure. This must match the value used on the Wireless Router. The default value is Untitled
Note! The SSID is case sensitive. By default, WEP on the Wireless Router is disabled.
If WEP remains disabled on the Wireless Router, all stations must
have WEP disabled.
If WEP is enabled on the Wireless Router, each station must use the
same settings as the Wireless Router.

Troubleshooting
A
Overview
This chapter covers some common problems that may be encountered while using the Wireless Router and some possible solutions to them. If you follow the suggested steps and the Wireless Router still does not function properly, contact your dealer for further advice.
General Problems
Problem 1: Can't connect to the Wireless Router to configure it. Solution 1:
Check the following:
The Wireless Router is properly installed, LAN connections are OK,
and it is powered ON.
Ensure that your PC and the Wireless Router are on the same network
segment. (If you don't have a router, this must be the case.)
If your PC is set to "Obtain an IP Address automatically" (DHCP
client), restart it.
If your PC uses a Fixed (Static) IP address, ensure that it is using an IP
Address within the range 192.168.1.1 t o 19 2. 16 8.1.253 and thus compatible with the Wireless Router's default IP Address of
192.168.1.254. Also, the Network Mask should be set to 255.255.255.0 to match the Wireless Router. In Windows, you can check these settings by using Control Panel- Network to check the Properties for the TCP/IP protocol.
Internet Access
Problem 1: When I enter a URL or IP address I get a time out error. Solution 1:
Problem 2: Some applications do not run properly when using the Wireless Router. Solution 2: The Wireless Router processes the data passing through it, so it is not
A number of things could be causing this. Try the following troubleshooting steps.
Check if other PCs work. If they do, ensure that your PCs IP settings are
correct. If using a Fixed (Static) IP Address, check the Network Mask, Default gateway and DNS as well as the IP Address.
If the PCs are configured correctly, but still not working, check the
Wireless Router. Ensure that it is connected and ON. Connect to it and check its settings. (If you can't connect to it, check the LAN and power connections.)
If the Wireless Router is configured correctly, check your Internet
connection (DSL/Cable modem etc) to see that it is working correctly.
transparent. Use the Special Applications feature to allow the use of Internet applications, which do not function correct l y . If this does solve the problem you can use the DMZ function. This should work with almost every application, but:
It is a security risk, since the firewall is disabled.
Only one (1) PC can use this feature.
Wireless Access
Problem 1: My PC can't locate the Wireless Portable Router. Solution 1:
Problem 2: Wireless connection speed is very slow. Solution 2:
Check the following.
Your PC is set to Infrastructure Mode. (Access Points are always in
Infrastructure Mode)
The SSID on your PC and the W ireless Portable Router are the same.
Remember that the SSID is case-sensitive. So, for example "Workgroup" does NOT match "workgroup".
Both your PC and the Wireless Router must have the same setting for
WEP. The default setting for the Wireless Router is disabled, so your wireless station should also have WEP disabled.
If WEP is enabled on the Wireless Router, your PC must have WEP
enabled, and the key must match.
If the Wireless Router's Wireless screen is set to Allow LAN access to
selected Wireless Stations only, then each of your Wireless stations
must have been selected, or access will be blocked.
To see if radio interference is causing a problem, see if connection is
possible when close to the Wireless Router. Remember that the connection range can be as little as 100 feet in poor environments.
The wireless system will connect at the highest possible speed, depending on the distance and the environment. To obtain the highest possible connection speed, you can experiment with the following:
Wireless Router location.
Try adjusting the location and orientation of the Wireless Router.
Wireless Channel.
If interference is the problem, changing to another channel may show a marked improvement.
Radio Interference.
Other devices may be causing interference. You can experiment by switching other devices Off, and see if this helps. Any "no i sy " devices should be shielded or relocated.
RF Shielding.
Your environment may tend to block transmission between the wireless stations. This will mean high access speed is only possible when close to the Wireless Router.

About Wireless LANs

BSS
BSS
A group of Wireless Stations and a single Access Point, all using the same ID (SSID), form a Basic Service Set (BSS). Using the same SSID is essential. Devices with different SSIDs are unable to communicate with each other.
Channels
The Wireless Channel sets the radio frequency used for communication.
Access Points use a fixed Channel. You can select the Channel used. This allows you to
choose a Channel which provides the least interference and best performance. In the USA and Canada, 11 channel are available. If using multiple Access Points, it is better if adjacent Access Points use different Channels to reduce interference.
In "Infrastructure" mode, Wireless Stations normally scan all Channels, looking for an
Access Point. If more than one Access Point can be used, the one with the strongest signal is used. (This can only happen within an ESS.)
WEP
WEP (Wired Equivalent Privacy) is a standard for encrypting data before it is transmitted. This is desirable because it is impossible to prevent snoopers from receiving any data that is transmitted by your Wireless Stations. But if the data is encrypted, then it is meaningless unless the receiver can decrypt it.
If WEP is used, the Wireless Stations and the Access Point must have the same settings for each of the following:
WEP Key WEP Authentication
Off, 64 Bit, 128 Bit For 64 Bit encryption, the Key value must match. For 128 Bit encryption, the Key value must match Open System or Shared Key.
Wireless LAN Configuration
To allow Wireless Stations to use the Access Point, the Wireless Stations and the Access Point must use the same settings, as follows:
Mode
SSID (ESSID)
WEP
On client Wireless Stations, the mode must be set to "Infrastructure". (The Access Point is always in "Infrastructure" mode.) Wireless Stations should use the same SSID (ESSID) as the Access Point they wish to connect to, but the SSID can not set to be null (blank). The Wireless Stations and the Access Point must use the same settings for WEP (Off, 64 Bit, 128 Bit). WEP Key: If WEP is enabled, the Key must be the same on the Wireless Stations and the Access Point. WEP Authentication: If WEP is enabled, all Wireless Stations must

use the same setting as the Access Point (either "Open System" or "Shared Key").
