Intel(R) PROSet utility provides the following tabs (pages):
The General page contains basic information about your connection. If you are associated to a network it will contain information such as SSID, profile name, speed, AP settings such as 802.11 band, channel and security mode. The Signal Quality section of the General page contains information on the quality of the wireless signal. It varies from poor to excellent depending on the surroundings and quality of the signal from the access point. The current status of the radio is also displayed in the Intel(R) PROSet General page. Refer to Switching the Radio Off/On for details about how to switch the radio off and on. Click the details button on the General page to view detailed parameters of the access point and network adapter.
The Network page displays the available profiles in the Profiles List. Profiles can be arranged in order of network connection priority. You can connect to one network using the first profile in the Profiles List then automatically connect to another network using the next profile. This allows you to stay connected while roaming freely from one wireless network to another. Although you can assign multiple profiles to a single network, you can only use one profile per connection. To add a new profile, use the Profile Wizard sequence of dialogs to configure the profile contents. The following sections discuss how to setup and configure a profile to connect to a network.
Use the Adapter tab options to configure ad hoc settings, set the power management and transmission power options.
Power Settings: These settings allow you to adjust the adapter's power transmission level, between the computer's power source and the battery life for maximum performance.

Use the Troubleshooting tab to access statistical information for the current wireless connection. You can also enable and disable logging and view log files from this dialog. To access the Statistics dialog click the Statistics button.
Signal Quality and Strength display: View the current signal quality and strength in percent values. Shows how the adapter is communicating with the currently associated wireless router.
Missed AP beacons: Percent value for the number beacons missed by the adapter. The lower the number is, the better the signal is.
Transmit retries: Percent value for the number of data packets that had to be retransmitted by the adapter. The lower the number is, the better the signal is.
Throughput: Current throughput speed measured in mega-bits-per-second (Mbps).
Network Name (SSID): Name of the network that the wireless adapter is connected to.
Profile Name: Name of current profile being used.
Operating Mode: Name of the operating mode being used; Infrastructure (AP) or Ad hoc.
Speed: The rate of data transmission between the adapter and wireless router measured in mega-bits-per-second (Mbps). The transmit data rate can depend on how far the adapter is from the wireless router. The adapter automatically sets the data rate (802.11b - 11, 5.5, 2, or 1).
Channel (Frequency): Displays the current channel and frequency being used.
Band: Displays 802.11b.
Use the Advanced Settings options to configure the wireless connections and profile management preferences. Use the import and export profiles button to access the into the Profiles list.

The Intel(R) PROSet for Wireless Advanced Settings (System-Wide Options) can be remotely set and updated using a small file named swo.ini. The swo.ini is used to import System-Wide Options. It contains all of the System-Wide Options as settings, lists the purpose of each setting and the possible values for the settings. When the swo.ini is placed in the auto-import folder Program Files\Intel\PROSetWireless\PROSet\Import, PROSet will automatically apply the settings from the swo.ini if any of the settings in the System-Wide Options are different from those of the swo.ini.
The swo.ini can also add, change, or remove the password from the System-Wide Options. If no password is set on the System-Wide Options when the swo.ini is imported, the settings will be applied from the swo.ini to the System-Wide Options including a password for the System-Wide Options if a password is included in the swo.ini. If there is a password on the System-Wide Options when the swo.ini is imported, the password in the swo.ini must match that of the System-Wide Options, otherwise no changes will be made. There are two fields in the swo.ini for passwords on the System-Wide Options: Old password and New password. The Old Password entry is used to match the current System-Wide Options password to allow for swo.ini changes. The New Password entry is used to add a password to the System-Wide Options when used by itself, or change the password of the System-Wide Options when used in conjunction with the Old Password entry.
There is a utility file named swo.exe which allows for the entry of an alphanumeric string which will be converted to an encrypted password when the Encrypt button is clicked. This encrypted password can be copied into either of the password entries of the swo.ini. Please see the contents of swo.ini for additional details on usage. The swo.ini and swo.exe files are located in the following path: <your drive letter> (e.g. C:) \PROSet\AdminKit.
