If this equipment does cause harmful interference to radio or television reception, which can be determined by turning the equipment off and on, the user is encouraged to try to correct the interference by one or more of the following measures: · · · Reorient or relocate the receiving antenna. Connect the equipment into an outlet on a circuit different from that to which the receiver is connected. [. . . ] Insert the Resource CD into your CD-ROM drive, click Start and choose Run. In the field that appears, enter F:\XXX\Setup. exe (if "F" is the letter of your CD-ROM drive; XXX is the setup program path, which is labeled on the Resource CD), Figure 2-1 should then appear. 4 TL-WN881ND/TL-WN552AG/TL-WN553AG 2. 54M Wireless Adapter User Guide You can click Cancel to end the installation on the Preparing Setup screen of Figure 2-1. After the files have been successfully copied, the screen in Figure 2-9 will appear. Click OK to reboot the system. Figure 2-9 Finish 8 TL-WN881ND/TL-WN552AG/TL-WN553AG 54M Wireless Adapter User Guide Chapter 3. Configuration TP-LINK Wireless Adapter TL-WN881ND/TL-WN552AG/TL-WN553AG can be configured by TP-LINK Wireless Client Utility (TWCU). This chapter describes how to configure your TP-LINK Wireless Adapter for wireless connectivity on your Wireless Local Area Network (WLAN) and use the data security encryption features. After Installing the Adapter, for the first time a region selector box appears, as shown in Figure 3-1. Select your region and click OK. Figure 3-1 Region Selector Note: You can also change your region with TP-LINK Wireless Client Utility in options. It appears at the bottom of the screen, and shows the signal strength using color and the received signal strength indication If the icon is gray, there is no connection. If the icon is red, there is poor signal strength and the RSSI is less than 5dB. If the icon is yellow, there is poor signal strength and the RSSI is between 5dB and 10dB. If the icon is green, there is good signal strength and the RSSI is between 10dB and 20dB. To define shared encryption keys, choose the Shared Key radio button and click Configure to fill in the Define Shared Keys window. None: No security (not recommended). Figure 3-7 Define Shared Keys Note: If the access point that the wireless adapter is associating to has WEP set to Optional 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. Edit the Advanced tab Power Save Mode · Maximum - Selects maximum mode to let the access point buffer incoming messages for the wireless adapter. The adapter will detect the access point if any messages are waiting periodically. Normal - In Normal mode, the adapter will be switched to maximum mode automatically when no large packets are retrieved. Off - turns power saving off, thus powering up the wireless adapter continuously for a short message response time. · · Network Type: Select Infrastructure or Ad Hoc. The default setting is Short & Long (access point mode), which allows both short and long headers in the 802. 11b frames. The adapter can only use short radio headers if the access point supports and uses them. Wireless Mode: Specifies 5 GHz 54 Mbps or 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. [. . . ] 802. 11g - specification for wireless networking at 54 Mbps using direct-sequence spread-spectrum (DSSS) technology, using OFDM modulation and operating in the unlicensed radio spectrum at 2. 4GHz, and backward compatibility with IEEE 802. 11b devices, and WEP encryption for security. 802. 11a - specification for wireless networking at 54 Mbps using OFDM modulation and operating in radio band at 5GHz. Ad-hoc Network - An ad-hoc network is a group of computers, each with a wireless adapter, connected as an independent 802. 11 wireless LAN. Ad-hoc wireless computers operate on a peer-to-peer basis, communicating directly with each other without the use of an access point. [. . . ]
