Table "Radio Characteristics" lists the typical ranges when used indoors: · In Open Office environments, clients can "see" each other, i. e. there are no physical obstructions between them. · In Semi-open Office environments, work space is separated by room dividers; client cards are at desktop level. · In Closed Office environments, workspace is separated by floor-to-ceiling brick walls. 62 Specifications Note: The range values listed in Table "Radio Characteristics" are typical distances as measured at Buffalo Technology AirStation laboratories. These values are provided for your guidance but may vary according to the actual radio conditions at the location where the AirStation product is installed. AirStation IEEE 802. 11 Channel Sets The range of the wireless signal is related to the Transmit Rate of the wireless communication. Communications at a lower Transmit range may travel longer distances. Center Channel ID FCC 1 2412 2 2417 3 2422 4 2427 5 2432 6 2437 7 2442 8 2447 9 2452 10 2457 11 2462 11 default channel 63 Troubleshooting Common Problems · · · · Out of range, client cannot connect to the AirStation. Configuration mismatch, client cannot connect to the AirStation. Absence or conflict with the Client Driver. Conflict of another device with the AirStation hardware. LED Activity Monitoring LED activity helps identify problems. · Power LED should be Green, · Wireless LED should be Green if the line is active. If is it blinking Green, wireless communication is active. · Ethernet LED should be Green (100Mbps) or Amber (10Mbps) while the communication is active. · The Red Diag LED will flash during boot and firmware updates. DIAG LED Activity Unplug the power for three seconds. Plug the power back in to monitor the Diag LEDs during start-up. 64 Troubleshooting DIAG LED Activity Table DIAG LED Display Continuous Red Red flash, 3 times Red flash, 4 times Time Starting Starting Starting Description/Action RAM Error Red flash, 2 times Starting Flash ROM Error A problem on the wired LAN side A problem on the wireless LAN side LEDs Work But Client PC Cannot Connect to Network If the LEDs indicate that the network is working properly (Power LED is on, Transmit/ Receive LED blinks), check the TCP/IP settings of the network. Changing Client TCP/IP Settings in Windows Consult the LAN Administrator for correct TCP/IP settings. [. . . ] 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 or more 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.
