[. . . ] Inform yourself about the local separate collection system for electrical and electronic products marked by this symbol. 1. 2 Network range & speed information · The environment : Radio signals can travel further outside of buildings, and if the wireless components are in direct line of sight to one another. Putting wireless components in high places helps avoiding physical obstacles and provides better coverage. · Building construction such as metal framing and concrete or masonry walls and floors will reduce radio signal strength. Avoid putting wireless components next to large solid objects; or next to large metal object such as computers, monitors, and appliances. [. . . ] Auto Save Profile On/Off When Auto profile is On, the New profile and Save profile buttons will be disabled. After you Apply Change a profile will automatically be created with your network settings. The Configuration tab contains three sub-tabs : Common, Security and Auto Config. First, click the Security ON/OFF button to enable or disable wireless security. Authentication Type - Choose WEP, WPA-PSK or WPA2-PSK depending on the type of wireless security in the rest of your wireless network. Wired Equivalent Privacy (WEP) and WiFi Protected Access (WPA/WPA2) are implemented in the adapter to prevent unauthorized access to your wireless network. Using your Wireless USB Adapter 7 Key Type - For more secure data transmissions, set encryption to the highest number of bits. Note The setting must be the same for all clients in your wireless network. Use Passphrase - If Passphrase is selected, security keys for WEP encryption are generated from your passphrase string. You must use the same Passphrase and Default Key settings on all the other routers in your network. It shows you the following information : · Network type shows the network setup · The name of the wireless connection (Network Name, or SSID) · Network mode shows which WiFi standard is used 8 Using your Wireless USB Adapter · · · · An icon reflecting if encryption is enabled Signal strength Channel that is used by the network MAC address of the device Double-click one of the network names to open the Profile Wizard for establishing a wireless connection with that network. 4. 2. 5 Version Information tab Selecting this tab displays vendor and version information. Using your Wireless USB Adapter 9 ONE-ON-ONE WIRELESS NETWORK 5 Network Terminology In a network, the computers need to be able to connect to each other physically. Therefore, another important network property is how the computers connect to each other, either directly or through a central device. 2 PCs) Also known as : Ad Hoc / Peer-to-Peer WIRELESS NETWORK WITH MORE THAN 2 PCs Note Use a crossover Ethernet cable to connect two computers directly to each other. WIRED NETWORK WITH MORE THAN 2 PCs Also known as : Ad Hoc / Peer-to-Peer The wireless medium forms a hub in and of itself. CONNECTING WIRELESS TO WIRED NETWORKS Use a hub or switch to connect more than 2 PCs to each other. Note Use straight-through Ethernet cables to connect the computers to the central device (hub/switch). HOW TO INTERCONNECT WIRED NETWORKS Also known as : Infrastructure / Access Point Use a Wireless Router Central devices, like a hub, switch, router or wireless access point may be stand-alone devices or built into a computer. · A hub has multiple ports and serves as a central connection point for communication lines from all computers on a wired network. A switch is similar to a hub, but is able to handle different network speeds at each port. · Gateway routers and wireless access points route network traffic from one network to another (e. g. from a wired network to the Internet, or from a wireless network to a wired network or to the Internet). Use a gateway router to connect one network to another (e. g. to the Internet, also known as WAN). 10 Network Terminology 6 Technical data Radio · IEEE 802. 11b/g/n (Draft 2. 0) Radio Technology · Direct Sequence Spread Spectrum (DSSS) · Orthological Frequency Division Multiplexing (OFDM) Operating Frequency · 2400~2483, 5 MHz Channel Numbers : · 13 channels (Europe) · 11 channels (US) · 14 channels (Japan) Antenna Type · Built-in antennas Data Rate · 54 Mbps Max Wireless Security · WEP 64/128 bit · WPA/WPA2 · WPA/WPA2-Personal (PSK) · WPA-PSK with TKIP · WPA2-PSK with AES · WPA-PSK + WPA2-PSK with TKIP+AES. AES, or TKIP Host Interface · High speed USB 2. 0 interface Power Consumption · Approx. 500mA/420mA Dimensions (h x w x d) · 22 x 79 x 93 mm Weight · Approx. [. . . ] If it still does not work, try re-installing the wireless USB adapter from the original Installation CD. I cannot access any network resources from the computer · Make sure the computer and other network devices are receiving power. I have no access to a Windows or NetWare service on the network · Check that you have enabled and configured the service correctly. If you cannot connect to a particular server, be sure that you have access rights and a valid ID and password. [. . . ]
