SSID
The service set identifier (SSID) is the name given to a wireless network by its
administrator(s). The default value is Any, which allows the device to connect to any access
point in the Infrastructure Mode, or to any other wireless device in the Ad Hoc Mode. The
SSID can be up to 32 characters long, and is case sensitive.
Power Save Mode
Selects a power-save mode from three preconfigured settings:
•
CAM (Continuous Access Mode) Highest performance with no power saving.
•
Max PSP (Max Power Saving Mode) Maximum power saving with reduced
performance.
•
Fast PSP (Fast Power Saving Mode) Greater power saving than CAM and higher
performance than Max PSP.
Operation Mode
Determines the type of network or mode of operation.
•
Ad Hoc Mode For peer-to-peer networking with other wireless devices without routing
through wired network.
•
Infrastructure Mode (default) For connecting to a wired network via an access point.
•
AP Mode For setting up the device as an access point. Note: In order to function as an
access point, your computer must be physically connected to a wired network.

Radio Status
Shows whether the radio is on or off.
Data Rate
Selects the rate of transmission between your computer and the access point (in the
infrastructure mode) or another wireless device (in the ad hoc mode). In general, a higher
transmission rate would provide a smaller coverage area, and a lower transmission rate
would cover a greater distance. The default setting is Auto Rate, which allows the device to
start at 54 Mbps and automatically lowers the transmission rate when necessary.
Channel
Selects the frequency channel for the transmission in the Ad Hoc Mode or AP Mode.
Fragment Threshold
Defines the size at which packets are fragmented. The acceptable range of values is from
256 to 2312 bytes, and the default value is 2312 bytes.
RTS Threshold
Defines the size at which packets are sent via the RTS-CTS mechanism. The acceptable
range of values is from 0 to 2312 bytes, and the default value is 2312 bytes.
Network Type
Selects the 802.11 network protocol usage; there are three modes, “802.11b only”,
“802.11g”, and “Auto”. The default setting is Auto.
WEP config
Controls the authentication and encryption configurations for the device.

Encryption state
Determines whether Wired Equivalent Privacy (WEP) is used for data encryption.
•
None (default) No encryption.
•
WEP Data is encrypted with a WEP key. Up to four WEP keys can be specified. Each
key can have a length of 40, 128, or 256 bits.
Authentication Mode
Determines the method of authentication.
•
Open System (Default) A null authentication algorithm is used, which allows the device
to be authenticated by any access point or other devices with an appropriate SSID.
•
Shared Key A WEP key is used as a means of authentication, which allows the device
to be authenticated only by access points or other devices that has the same WEP key in
addition to an appropriate SSID.

4.1.6. Profiles
A profile is a set of preconfigured settings for a particular network environment. Having
different profiles stored in WiFiset, you can move from one network to another without having
to reconfigure the network settings.
4.1.6.1. Adding a new profile
Before adding the current network configuration as a new profile, make sure that your device
is connected to a network and that all settings are properly configured. To add a profile in
WiFiset, please follow these steps:
Step 1. Click Profile in WiFiset’s menu bar, and then click Add to create a new profile based
on the current network’s configurations.

User's Manual
VIA Technologies, Inc.
This device is intended only for OEM integrators under the following conditions:
The antenna must be installed such that 20 cm is maintained between the antenna and users,
and
The transmitter module may not be co-located with any other transmitter or antenna.
As long as 2 conditions above are met, further transmitter test will not be required. However,
the OEM integrator is still responsible for testing their end-product for any additional
compliance requirements required with this module installed (for example, digital device
emissions, PC peripheral requirements, etc.).
IMPORTANT NOTE: In the event that these conditions can not be met (for example certain
laptop configurations or co-location with another transmitter), then the FCC authorization is
