Additional information Symptom Forgot the encryption key. Transfer rate is 11 Mbps, but MPEG2 data does not transfer without interruption. Communication fails although the computer is located within 100 m (330 feet) of the Access Point. Link test results in many dropped messages. Cause/Remedy c Return Access Point to factory default settings and then reconfigure it. For details, see the documentation of the Access Point. 11 Mbps is a theoretical value. Under real-world conditions, transfer rate will normally be in the range of 4 - 5 Mbps. This is true for all IEEE 802.11b compliant systems. The bandwidth available with wireless communications may not be sufficient for high-volume streaming data such as MPEG2. The actual communication distance depends on various factors such as installation site conditions, presence of obstacles, and so on. c Move the computer closer to the Access Point. The Access Point and the computer are too far apart. c Move the computer closer to the Access Point. File transfer is in progress on the network. c During transfer of large files, performance may temporarily drop. Repeat the test when the network is not being used for file transfer. There is radio interference. c If there is another wireless station nearby using the same channel, try changing the channel number. c If a Bluetooth-enabled wireless device is being used nearby, stop using it at the same time. A microwave oven is being used nearby. c A microwave oven may also have an adverse effect on communication performance. Do not use it at the same time. Notes • When more than 2% of messages are dropped, communication performance will be seriously affected. At 5% and higher, most network applications will have trouble functioning. • Perform the link test for at least 1 minute continuously (minimum 200 messages) to ensure meaningful results. 55
