If you are using Windows XP and you cannot get the Wireless Zero Configuration to start or you simply do not see any wireless functionality on your system, the service may have been disabled by a third party application. Please check with Microsoft for assistance on re-enabling the service. If you suspect a power outlet to be faulty, plug another device into it to verify that it is working. · · · · · If your wireless station cannot communicate with a computer on the Ethernet LAN when configured for Infrastructure mode, try changing the wireless channel on the AP. Make sure the SSID is the same as that used by the AP for a station with roaming disabled, or the same as that used by the AP's in the extended service set (ESS). The Access Point you are trying to attach to is defective or may not be configured properly to accept your signal. Check with the administrator of your wireless network for more information on connecting to the LAN. Also run the necessary diagnostics on the AP to make sure the unit is fully operational. If you cannot access the Internet, be sure to check with the ISP for further instructions once the drivers for the Wireless Card are installed properly. 9 | Frequently Asked Questions · What is a Wireless LAN?o 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. ). o 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. o 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. o In order for your wireless components to interact with traditional wired networks they need a media bridge to translate for them. An ACCESS POINT is attached to the network using CAT-5 Ethernet cable attaching to a hub, switch or another PC. Wireless PC's can then communicate to Wired Ethernet computers through this access point. [. . . ] Medium Dependent Interface ­ X (crossed) - A port on a network hub or switch that crosses the transmit lines coming in to the receive lines going out. This is an audio compression technology that is included in the MPEG-1 and -2 specifications. MP3 encoding can allow you to compress CD-quality sound by a factor of 12. MPEG-1 can provide resolution of 352x240 at 30 frames/second (fps) with 24-bit color and CD-quality sound. [. . . ]
