[. . . ] Select or clear the WPN111 "Use Windows to configure my wireless network settings" check box. I cannot connect to the AP that I want from the Networks browser list The access point is available and there is good signal strength. There are a few possibilities: · If the access point (AP) is WPA-PSK protected, you will need to have the correct WPA-PSK passphrase. Otherwise, the WPN111 will still be connected to the previous access point and you will not be able to change to the WPA-PSK access point. If the access point is WEP protected (either 64 or 128 bit encryption), you will be prompted to enter the WEP encryption security information. · New Hardware Wizard appears after installation has completed This happens if the USB device is connected to a different port than the one used during installation. Return the USB device to the original USB port.

Wireless Networking Overview The RangeMaxTM WPN111 Wireless USB 2. 0 Adapter conforms to the Institute of Electrical and Electronics Engineers (IEEE) 802. 11b standard for wireless LANs (WLANs) and a product update will bring the WPN111 into conformance to the 802. 11g standard when it is ratified. On an 802. 11b or g wireless link, data is encoded using direct-sequence spread-spectrum (DSSS) technology and is transmitted in the unlicensed radio spectrum at 2. 5GHz. The maximum data rate for the 802. 11b wireless link is 11 Mbps, but it will automatically back down from 11 Mbps to 5. 5, 2, and 1 Mbps when the radio signal is weak or when interference is detected. The 802. 11g auto rate sensing rates are 1, 2, 5. 5, 6, 9, 11, 12, 18, 24, 36, 48, and 54 Mbps. Likewise, the 802. 11a wireless link offers a maximum data rate of 54 Mbps, but will automatically back down to rates 48, 36, 24, 18, 12, 9, and 6 Mbps. The 802. 11 standard is also called Wireless Ethernet or Wi-Fi by the Wireless Ethernet Compatibility Alliance (WECA, see http://www. wi-fi. net), an industry standard group promoting interoperability among 802. 11 devices. The 802. 11 standard offers two methods for configuring a wireless network - ad hoc and infrastructure. Infrastructure Mode With a wireless access point, you can operate the wireless LAN in the infrastructure mode. This mode provides wireless connectivity to multiple wireless network devices within a fixed range or area of coverage, interacting with wireless nodes via an antenna. In the infrastructure mode, the wireless access point converts airwave data into wired Ethernet data, acting as a bridge between the wired LAN and wireless clients. Connecting multiple access points via a wired Ethernet backbone can further extend the wireless network coverage. As a mobile computing device moves out of the range of one access point, it moves into the range of another. As a result, wireless clients can freely roam from one access point domain to another and still maintain seamless network connection. Wireless Networking Basics 202-10076-01 B-1 User Manual for the NETGEAR RangeMaxTM Wireless USB 2. 0 Adapter WPN111 Ad Hoc Mode (Peer-to-Peer Workgroup) In an ad hoc network, computers are brought together as needed; thus, there is no structure or fixed points to the network - each node can generally communicate with any other node. This mode enables you to quickly set up a small wireless workgroup and allows workgroup members to exchange data or share printers as supported by Microsoft networking in the various Windows operating systems. Some vendors also refer to ad hoc networking as peer-to-peer group networking. In this configuration, network packets are directly sent and received by the intended transmitting and receiving stations. As long as the stations are within range of one another, this is the easiest and least expensive way to set up a wireless network. Network Name: Extended Service Set Identification (ESSID) The Extended Service Set Identification (ESSID) is one of two types of Service Set Identification (SSID). [. . . ] These names are alphanumeric names, up to 16 characters in length. Network Address Translation NAT. A technique by which several hosts share a single IP address for access to the Internet. NIC Network Interface Card. An adapter in a computer which provides connectivity to a network. packet A block of information sent over a network. A packet typically contains a source and destination network address, some protocol and length information, a block of data, and a checksum.
