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. 14 TL-WN721N 150Mbps Wireless Lite-N USB 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 USB 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 TL-WN721N 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. An Ad-Hoc network contains only clients, such as laptops with wireless desktop adapters. 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 2) 15 TL-WN721N of the access point with which it associates. 150Mbps Wireless Lite-N USB Adapter 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. [. . . ] DSSS - (Direct-Sequence Spread Spectrum) - DSSS generates a redundant bit pattern for all data transmitted. 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).
