[. . . ] However, there is no guarantee that interference will not occur in a particular installation. 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 of the following measures: • Reorient or relocate the receiving antenna. • Increase the separation between the equipment and receiver. • Connect the equipment into an outlet on a circuit different from that to which the receiver is connected. [. . . ] Then you will return to the Profile Tab (Figure 3-2). A reboot is not needed for changes to take effect. Figure 3-8 Advanced Description of items in Figure 3-8 is as follows: Wireless Mode: Sets infrastructure Protocols, including 802. 11 B/G mix and 802. 11 B Only. (Default 802. 11 B/G mix) 19 Ad Hoc Wireless Mode: Sets Ad Hoc Wireless Protocols, including 802. 11 B/G mix, 802. 11 B Only and 802. 11 G Only. (Default: 802. 11 B/G mix) TX Burst: The longest interval between frames is normally one DIFS while frames are transmitted. When this setting is open, the longest interval between frames is one SIFS that means the system is allowed to transmit higher capacity of data in one interval. (Default: OFF) B/G Protection: 802. 11b uses CCK modulation. 802. 11g uses OFDM while CCK modulation for 802. 11b is compatible. To prevent data collision between two stations with 802. 11b and 802. 11g within range of the same Access Point, it is necessary to set 11B/G Protection. This setting only functions when 802. 11 B/G mix is selected as Wireless Mode. Three setting are available: AUTO, ENABLE and DISABLE. This is a mechanism implemented to prevent the “Hidden Node” problem, “Hidden Note” is a situation in which two stations are within range of the same Access Point, but are not within range of each other. Therefore, they are hidden nodes for each other and can not detect each other. Rescan: Rescan the available networks and then re-display results. Connect: Connects with the highlighted Access Point. Add to Profile: Adds a specific Access Point into the profile. 3. 4. Statistics Tab The Statistics tab shows you the number of packets sent and received by the Adapter (see Figure 3-11) Figure 3-11. Statistics Description of items in Figure 3-11 is as follows: 23 Frames Transmitted Successfully: Number of frames transmitted successfully. Frames Transmitted Successfully Without Retry: Number of frames transmitted successfully, excluding packets transmitted successfully with more than one retry. Frames Transmitted Successfully After Retry[s]: Number of frames transmitted successfully with more than one retry. Frames Fail To Receive ACK After All Retries: Number of frames failing to receive ACK after many retries. RTS Frames Successfully Receive CTS: Number of RTS frames successfully received CTS (Clear To Send) from AP. RTS Frames Fail To Receive CTS: Number of RTS frames fail to receive CTS from AP. Frames Receive Successfully: Number of frames received successfully. Frames Receive With CRC Error: Number of frames received with CRC Errors. [. . . ] Connect the equipment into an outlet on a circuit different from that to which the receiver is connected. Consult the dealer or an experienced radio/TV technician for help. FCC Caution: To assure continued compliance, any changes or modifications not expressly approved by the party responsible for compliance could void the user authority to operate this equipment. This device complies with Part 15 of the FCC Rules. [. . . ]
