3.1 Preferences This screen allows you to define the setting of the wireless USB adapter operation. Statistic Update Interval: the sample rate in secs of the throughput. Parameter display units: Two display options for SNR signal strength either in dBm or in percent.
3.2 View Site This screen allows you to scan for the available access point or the wireless network (wireless clients and Access Points) and establish wireless communications with one. The resulting as below in terms of AP View displays the currently available access points that are received by the wireless USB adapter. Link Quality: Shows the link quality. quality. 100% presents the maximum connection Network Name (SSID): AP’s. SSID designated by the local network administrator.
Connect: connect to the selected network. Rescan: Initial a constant scanning and display an updated list of the access point and the network. AP View: Switch the display from Network View to AP View. Save Profile: save the selected network connection status as a profile. Clicking this button to save profile, the below screen with two tabs, general and security, pop up. Name: define your preferable name for this profile.
SSID: define the profile’s SSID. Network Mode: define the network mode (Infrastructure/ Ad-Hoc) for this profile. Auto-Select Profile member: Security: define the network encryption scheme including WEP and WPA. 802.1x: Check it to enable the 802.1x authentication protocol. Encryption Key (Hex): When security type is WEP, this is enabled. You can define up to 4 sets. At least one key must be defined.
3.3 General General is the status screen that shows the current information of the connection and link status. SSID: Shows the current SSID. Network Mode: Shows the current network mode (Infrastructure or Ad-Hoc) used for wireless communication. Channel / Frequency: Shows the current channel / frequency used for wireless network. Max. Network Rate: Shows the maximum data rate used for transmitting. example, 54Mbps is for 802.11g and 11Mbps is for 802.11b.
Sent: Shows the current Tx Rate (measured in Kbytes/sec) Network Data Rate: Shows the selected PHY bit rate. This rate varies between 1-54Mbps. 3.4 Profiles The profile is the setting of the Access Point. network name (SSID) and security. It contains three parts: profile name, Connect: click this button for connection based on the selected profile setting. New: click this button to create a new profile. Edit: click this button to edit the selected profile.
You could edit the selected / new profile as below screen after clicking the new or edit button. Name: define your preferable name for this profile. SSID: define the profile’s SSID. Network Mode: define the network mode (Infrastructure/ Ad-Hoc) for this profile. Security: define the network encryption scheme including WEP and WPA.
802.1x: Check it to enable the 802.1x authentication protocol. Encryption Key (Hex): When security type is WEP, this is enabled. You can define up to 4 sets. At least one key must be defined. 3.5 Current Statistics This screen graphically displays the received and sent traffic rates of the wireless USB adapter. The graphs sample time is definable by users in the preference option. Signal Strength: Shows the received signal strength SNR: the ratio of the signal strength and the noise.
3.6 About This page displays some information about the 54Mpbs wireless USB adapter, which includes the version numbers for Driver, Firmware and Utility. When there is new version of software available for upgrade, you will be able to identify by version numbers. 4. Glossary Access Point: An internetworking device that seamlessly connects wired and wireless networks. Ad-Hoc: An independent wireless LAN network formed by a group of computers, each with a network adapter.
two formats that you can use for entering the values for WEP key. It represents English letters as numbers from 0 to 127. Authentication Type: Indication of an authentication algorithm which can be supported by the Access Point: 1. Open System: Open System authentication is the simplest of the available authentication algorithms. Essentially it is a null authentication algorithm. Any station that requests authentication with this algorithm may become authenticated if 802.
amount of time before retrying. If the network is quiet and two devices access the line at exactly the same time, their signals collide. When the collision is detected, they both back off and wait a random amount of time before retrying. DHCP: Dynamic Host Configuration Protocol, which is a protocol that lets network administrators manage and allocate Internet Protocol (IP) addresses in a network.
heavy interference caused by the big size of transmission frame. But if the frame size is too small, it will create the overhead during the transmission. Gateway: a device that interconnects networks with different, incompatible communication protocols. HEX: Hexadecimal, HEX, consists of numbers from 0 – 9 and letters from A – F.
PSDU: PLCP service data unit Roaming: A LAN mobile user moves around an ESS and enjoys a continuous connection to an Infrastructure network. RTS: Request To Send. An RS-232 signal sent from the transmitting station to the receiving station requesting permission to transmit. RTS Threshold: Transmitters contending for the medium may not be aware of each other. RTS/CTS mechanism can solve this “Hidden Node Problem”.
Federal Communication Commission Interference Statement This equipment has been tested and found to comply with the limits for a Class B digital device, pursuant to Part 15 of the FCC Rules. These limits are designed to provide reasonable protection against harmful interference in a residential installation. This equipment generates, uses and can radiate radio frequency energy and, if not installed and used in accordance with the instructions, may cause harmful interference to radio communications.
