Additional information
Symptom Cause/Remedy
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.
cReturn 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.
cMove the computer closer to the Access Point.
The Access Point and the computer are too far apart.
cMove the computer closer to the Access Point.
File transfer is in progress on the network.
cDuring 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.
cIf there is another wireless station nearby using the same
channel, try changing the channel number.
cIf a Bluetooth-enabled wireless device is being used
nearby, stop using it at the same time.
A microwave oven is being used nearby.
cA 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.
