[. . . ] 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. [. . . ] 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. The channels available depend on the regulatory domain. If the adapter finds no other ad hoc adapters, the channel that the adapter starts the ad hoc network with will be selected automatically. The Adapter must match the wireless mode and channel of the clients it associates. 802. 11 Authentication Mode: Select which mode the Adapter uses to authenticate to an access point: · Auto - Automatic causes the adapter to attempt authentication using shared, but switches it to open authentication if shared fails. Open - Open System enables an adapter to attempt authentication regardless of its WEP settings. It will only associate with the access point if the WEP keys on both the adapter and the access point match. · Shared - Shared-key only allows the adapter to associate with access points that have the same WEP key. · For infrastructure (access point) networks, click Preferred APs. . . to specify four access points at most to the client adapter that attempts to be associated to the access points. The four access points have different priorities; the frontal has the higher priority. Figure 3-7 22 PW-DN481D 150Mbps Wireless Lite-N PCI-E Adapter 3. 2. 2 Remove a profile 1. [. . . ] Infrastructure mode is useful at a corporation scale, or when it is necessary to connect the wired and wireless networks. Spread Spectrum - Spread Spectrum technology is a wideband radio frequency technique developed by the military for use in reliable, secure, mission-critical communications systems. It is designed to trade off bandwidth efficiency for reliability, integrity, and security. In other words, more bandwidth is consumed than in the case of narrowband transmission, but the trade off produces a signal that is, in effect, louder and thus easier to detect, provided that the receiver knows the parameters of the spread-spectrum signal being broadcast.
