User manual SMC PW-DN481D

[. . . ] PW-DN481D 150Mbps Wireless Lite-N PCI-E Adapter Rev: 1. 0. 0 1910020267 FCC 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. However, there is no guarantee that interference will not occur in a particular installation. [. . . ] Client Name - Please enter the Profile name which identifies the client machine. 18 PW-DN481D 150Mbps Wireless Lite-N PCI-E Adapter Network Names (SSIDs) - Please enter the IEEE 802. 11 wireless network name. Edit the Security tab Select the Security tab in the screen above, and then you can edit the fields to configure the profile. To define the security mode, select the radio button of the desired security mode as follows. Figure 3-4 19 PW-DN481D WPA/WPA2: Wi-Fi Protected Access 150Mbps Wireless Lite-N PCI-E Adapter WPA/WPA2 Passphrase: Wi-Fi Protected Access Passphrase 802. 1x: Enables 802. 1x security. Pre-Shared Key (Static WEP): Enables the use of shared keys that are defined on both the access point and the station. To define shared encryption keys, choose the Shared Key radio button and click Configure to fill in the Define Shared Keys window (shown in Figure 3-5). Note: If the access point which the Adapter is associated has WEP set and the client has WEP enabled, make sure that Allow Association to Mixed Cells is checked on the Security tab to allow association. To complete WEP encryption configuration, you must select the 802. 11 Authentication Mode as appropriate on the Advanced tab of this Profile Management dialog. To configure the Encryption Keys under the Pre-Shared keys (Static WEP) Security mode: Figure 3-5 Note: Select different Security Options, the configurations are different; you can select the appropriate security option and configure the exact key as your need. Edit the Advanced tab This screen below allows you to make advanced configuration for the profile. 20 PW-DN481D 150Mbps Wireless Lite-N PCI-E Adapter Figure 3-6 Power Save Mode - Please select the power save mode in the drop-down list. · Maximum - Selects maximum mode to let the access point buffer incoming messages for the Adapter. The Adapter will detect the access point if any messages are waiting periodically. · Normal - Normal mode uses maximum when retrieving a large number of packets, then switches back to power save mode after retrieving the packets. Off - Turns power saving off, thus powering up the Wireless PCI-E Adapter continuously for a short message response time. · Network Type: There are basically two modes of networking: · · Infrastructure - All wireless clients will connect to an access point or wireless router. Ad-Hoc - Directly connecting to another computer, for peer-to-peer communication, using wireless network adapters on each computer, such as two or more PW-DN481D wireless adapters. Note: 1) An Infrastructure network contains an Access Point or wireless router. All the wireless devices or clients will connect to the wireless router or access point. 2) An Ad-Hoc network contains only clients, such as laptops with wireless desktop adapters. All the adapters must be in Ad-Hoc mode to communicate. 21 PW-DN481D 150Mbps Wireless Lite-N PCI-E Adapter Wireless Mode: Specifies 2. 4 GHz 150 Mbps, 2. 4 GHz 54 Mbps or 2. 4 GHz 11 Mbps operation in an access point network. The Wireless adapter must match the wireless mode of the access point with which it associates. Wireless Mode when Starting an Ad Hoc Network: Specifies 2. 4 GHz 54/11 Mbps to start an Ad Hoc network if no matching network name is found after scanning all available modes. This mode also allows the selection of the channel that the Wireless Adapter uses. If the adapter finds no other ad hoc adapters, the channel that the adapter starts the ad hoc network with will be selected automatically. [. . . ] Even if one or more bits in the chip are damaged during transmission, statistical techniques embedded in the receiver can recover the original data without the need of retransmission. To an unintended receiver, DSSS appears as low power wideband noise and is rejected (ignored) by most narrowband receivers. another wireless LAN endpoint), the DSSS signal is recognized as the only valid signal, and interference is inherently rejected (ignored). FHSS - (Frequency Hopping Spread Spectrum) - FHSS continuously changes (hops) the carrier frequency of a conventional carrier several times per second according to a pseudo-random set of channels.
