For verification purposes, you will be prompted to confirm that you have selected the correct WLAN. If the network is encrypted, you will be prompted to enter the appropriate keys. The "Connection State" column represents the MAC address of the wireless network. Other columns include "WEP", "Signal Strength", and "Channel". To modify settings, highlight the desired profile and click the [Modify] button. See the Configuration section below for more information. Figure 8. 2 Section 8. 3 | Configuration Figure 8. 3 To change the settings, simply enter the new desired values and click the [OK] button. The wireless adapter will automatically associate with the same channel that the network is using. If you will be roaming among multiple Access Points with different BSSID's, leave the SSID blank to allow the client to connect to the access point with the highest signal strength. Wireless Mode: The available options are "802. 11b", "802. 11a" or "Auto". 802. 11a Turbo Mode: This function disables or enables the 802. 11a Turbo mode. Select the "Wireless Networks" tab and uncheck the [Use Windows to configure my wireless network settings] check box. Figure 9. 0 10 | Frequently Asked Questions What is a Wireless LAN?A local area network that transmits over the air typically in an unlicensed frequency such as the 2. 4GHz band. A wireless LAN does not require lining up devices for line of sight transmission like IrDA. Wireless access points (base stations) are connected to an Ethernet hub or server and transmit a radio frequency over an area of several hundred to a thousand feet which can penetrate walls and other non-metal barriers. Roaming users can be handed off from one access point to another like a cellular phone system. Laptops use wireless network cards that plug into an existing PCMCIA slot or that are self contained on PC cards, while stand-alone desktops and servers use plug-in cards (ISA, PCI, etc. ). An AD-HOC network is a peer to peer network where all the nodes are wireless clients. As an example, two PC's with wireless adapters can communicate with each other as long as they are within range. A family of IEEE standards for wireless LANs first introduced in 1997. 802. 11 provides 1 or 2 Mbps transmission in the 2. 4GHz band using either a frequency hopping modulation (FHSS) technique or direct sequence spread spectrum (DSSS), which is also known as CDMA. The 802. 11b standard defines an 11 Mbps data rate in the 2. 4GHz band, and the 802. 11a standard defines 54 Mbps in the 5GHz band. [. . . ] These peer-to-peer networks are often simpler to install and manage, but dedicated servers provide better performance and can handle higher transaction volume. The message transfer is managed by a transport protocol such as TCP/IP and NetBEUI. The physical transmission of data is performed by the access method (Ethernet, Token Ring, etc. ), which is implemented in the network adapters that are plugged into the machines. The actual communications path is the cable (twisted pair, coax, optical fiber) that interconnects each network adapter. [. . . ]
