UANTA COMPUTER INC. WM1 Mini-PCI User Manual ______________________________________________________________________________ _______ 2 Wireless LAN Application Wireless LAN (Local Area Network) systems offer a great number of advantages over a traditional, wired system. And these systems support the same network configuration options of the legacy Ethernet LANs as defined by IEEE 802 standard committee. Besides, they are more flexibles, easier to setup and manage and often more cost effective than wired equivalence. In general, wireless LAN products can be configured as Ad-Hoc (Peer-to-

Peer) for departmental or SOHO LANs or Infrastructure (Access Point) for enterprise LANs. 2-1 Ad-Hoc Topology This is the peer-to-peer mode of operation without access point. An Ad-Hoc wireless LAN is a group of computers, each equipped with one wireless adapter, connected as an independent wireless LAN. Computers in a specific Ad-Hoc wireless LAN must be configured at the same radio channel and the same SSID for establishing the wireless connection. Ad-Hoc wireless LAN is applicable at a departmental scale for a branch or SOHO operation.

UANTA COMPUTER INC. WM1 Mini-PCI User Manual ______________________________________________________________________________ _______ 2-2 Infrastructure Topology This mode of operation requires the presence of an access point at least. In this mode, all wireless LAN client devices need to communicate with the access point and then access to a wired LAN such as Ethernet via the access point. Therefore, an integrated wireless and wired LAN is called an infrastructure configuration. A group of wireless LAN client users and an access point construct a Basic Service Set (BSS). Each wireless LAN client devices in this BSS can talk to any devices in the wired LAN infrastructure via the access point. In this infrastructure configuration, wireless LAN systems will extend the accessibility to the wired LAN. On the other hand, infrastructure mode also supports roaming capabilities for mobile wireless LAN users. More than one BSS can be configured as an Extended Service Set (ESS). The continuous network allow wireless LAN users to roam freely within an ESS. All wireless LAN client devices and access points within the ESS must be configured with the same ESS ID and use the same radio channel.

UANTA COMPUTER INC. WM1 Mini-PCI User Manual ______________________________________________________________________________ _______ Profile Name The name of the profile currently in use. Basic SSID The name of the SSID (Service Set Identification) associated with the profile State This field is used to display the current state of the driver. When the state associated means normal flow of operation in access point or peer-to-peer devices. During access point connection, it will represent the MAC address of the access point. And during an Ad-Hoc connection, it will read the MAC address of the peer-to-peer devices. A state of scanning means that the node is searching for available access point and can not detect any wireless device within range. Mode It will be shown the access point or peer-to-peer in this field. Access point This mode of operation requires the presence of an access point. All communication is done via the access point, which relays packets to other wireless clients in the BSS as well as to nodes on a wired network such as Ethernet. Peer-to-peer This is the peer-to-peer mode of operation. All communication is done from client to client without the use of an access point. Current Tx Rate It will shown the transmit rate is being currently used for an active connection. This value has no meaning when state is scanning Current Channel Channel being used, if any, for this wireless connection. It will shown the communication channel ranging from 1 to 11. Power Saving Mode Indicates of power saving mode is enable or disable. Power saving mode reduced energy usage by temporarily disconnecting wireless connections when the connection is idle. Rescan Pressing the rescan button causes the driver to restart and begin its connection procedure. The connection procedure differs depending on the mode of the driver. Advance RTS Threshold Indicated of RTS threshold is disable or the value ranging from 0 to 2432. Frag Threshold Indicated of frag threshold is disable or the value ranging from 256 to 2432. Beacon Interval Indicated of beacon interval is disable or the ranging from 20 to 1000. ________________________________________________________________________ WM1 User Manual Rev. 1A Page: 12

- Quanta Confidential -

UANTA COMPUTER INC. WM1 Mini-PCI User Manual ______________________________________________________________________________ _______ Name given to the profile. Any user can add 10 maximum different profiles if he wish. Defaults Pressing this button restores each field in the panel to its default value. The default value for each field as below. Basic SSID The name of the SSID (Service Set Identification) associated with the profile. The default value is ANY, This allows your wireless client to automatically associate to any access point in the vicinity of your wireless client. Mode This field allows you to select from a list of supported network mode. The modes displayed will have Access Point and Peer-to-Peer. The default value is Access Point. Current Tx Rate The transmission rate at which the data packets are transmitted by client of access point. You can set this to 1Mbps, 2Mbps, Auto 1 or 2Mbps, 5.5Mbps, 11Mbps, Fully Automatic. The default value is Fully Automatic. Peer-to-Peer Channel Changing the channel is only effective in Ad-Hoc networks. Networking operating infrastructure mode automatically scan for a channel. Be aware that when the peer-to-peer mode is selected, be sure to set your wireless stations with the same channel. Power Saving Mode The field allows you to set enable or disable. Power saving mode reduced energy usage by temporarily disconnecting wireless connections when the connection is idle. The default value is Disable. Advance RTS Threshold The field allows you to set enable or disable. When the field is enable, you can set the value ranging from 0 to 2432. 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. Thus, it provides a solution to prevent data collisions. Enabling RTS Threshold may cause redundant network overhead that could negatively affect the throughput performance. Frag Threshold The field allows you to set enable or disable. When the field is enable, you can set the value ranging from 256 to 2432. Fragmentation mechanism is used for improving the efficiency when high traffic flows along in the wireless network. If your wireless devices often transmit large files in wireless network, you can enable the Fragmentation Threshold and the mechanism will split the packet. Beacon Interval ________________________________________________________________________ WM1 User Manual Rev. 1A Page: 14

- Quanta Confidential -

UANTA COMPUTER INC. WM1 Mini-PCI User Manual ______________________________________________________________________________ _______ Changing the Beacon Interval is only effective in peer-to-peer mode. You can set the value ranging from 20 to 1000. Encryption Tab The Encryption tab is used to desire an additional measure of security on your wireless network, which can be achieved by using WEP (Wired Equivalent Privacy) encryption. To prevent unauthorized wireless stations from accessing data transmitted over the network, WEP can support high secure data encryption. WEP encrypts each frame transmitted from the radio using one of the Keys entered from this panel. When an encrypted frame is received, it will only be accepted if it decrypts correctly. This will only happen if the receiver has the WEP Key used by the transmitter. The Encryption tab contains some fields as below. Encryption [WEP security]

WEP Key Create Key Manually, Create Keys with Pass-phrase Key1, Key2, Key3, Key4 Use WEP key Encryption [WEP security]

The field allows you to set Disabled, 64-bit, 128-bit. When setting 64bit, or 128 bits, it means ________________________________________________________________________ WM1 User Manual Rev. 1A Page: 15

- Quanta Confidential -

UANTA COMPUTER INC. WM1 Mini-PCI User Manual ______________________________________________________________________________ _______ WEP security is used. WEP Key You can use Create Key Manually or Create Keys with Pass-phrase method to enter encryption keys. It allows the entry of four keys for 64-bit encryption and one set of 128-bit key according to WEP function select. To be written to the driver and registry, each key must consists of correct digits and letters. The detailed descriptions will be shown as below for these two kinds of methods:

Create Key Manually For 40-bits encryption:

- Five alphanumeric characters in the range of a-z, A-Z and 0-9. (e.g. MyKey)

- 10 digit hexadecimal values in the range of A-F and 0-9. (e.g. 11AA22BB33). For 128-bits encryption:

- 13 alphanumeric characters in the range of a-z, A-Z and 0-9. (e.g. WEPencryption).

- 26 digit hexadecimal values in the range of A-F and 0-9. (e.g. 11AA22BB33123456789ABCDEFF)

. Create Keys with Pass-phrase A Pass-phrase can be entered which is used as a seed to randomly generate the four keys. This saves considerable time since the same keys must be entered into each node on the wireless network. Key1, Key2, Key3, Key4 These four fields can be used to manually enter the keys. This may be necessary if you wish this node to match keys in a different vendor product. These fields also display the keys when they are generated using a Pass-phrase. Use WEP key This field updates the driver with the four keys displayed in Key1 through Key4. These keys are also written to the registry for permanent storage. For 128 bit encryption, this field will be invisible. About Tab The about tab is used to show Frequency Domain, Wireless Client management Utility version, Serial Number and MAC Address of this Network Interface Card, Network Interface Card Driver version and Network Interface Card firmware version. Users need to use these version numbers when reporting their problems to technique support. ________________________________________________________________________ WM1 User Manual Rev. 1A Page: 16
