Edit the Security tab Select the Security tab in the screen above, 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. 14 TL-WN811N Draft N Wireless CardBus Adapter Figure 3-4 WPA/WPA2: Wi-Fi Protected Access 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: The WEP security mode is not available for 802. 11n. 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: 15 TL-WN811N Draft N Wireless CardBus Adapter 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. 16 TL-WN811N Draft N Wireless CardBus 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 CardBus Adapter continuously for a short message response time. 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-WN811N wireless adapters. · · Network Type: There are basically two modes of networking: · · Note: 1) 2) 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. [. . . ] A set of two or more BSS in a single network is referred to as an Extended Service Set (ESS). 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. 25 TL-WN811N Draft N Wireless CardBus Adapter 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.
