How to resolve problems
Introduction
Make sure that the supplied Wireless Panel software is installed.
When using Windows XP, wireless connection settings are made using the built-in functions of Windows XP, but the Wireless Panel software is still useful
because it allows monitoring of network status and lets you selectively turn 802.11b (2.4 GHz) and 802.11a (5 GHz) transmission on/off.

z Hint
Access Point settings can be changed from the computer only after the connection between computer and Access Point has been established properly. If unable to
connect to the Internet, perform the above steps first, to ensure that communication between computer and Access Point functions normally.
■ Network Name indication does not show “Not Connected”, but IP address starts with “169.254. ...” or is
“0.0.0.0”?
If the IP address starts with “169.254. ...” or
is “0.0.0.0”, there may be a problem with
the settings for the wireless link between
the Access Point and the computer.
Is the IP address shown on the “Status” tab of the Wireless
Panel not starting with “169.254. ...” and not “0.0.0.0”?
There may be a mismatch in the data encryption settings. If connection to an Access Point for which data encryption is enabled was attempted with a
wrong encryption key (WEP key), the Network Name will be shown under the “Status” tab of the Wireless Panel, but the actual connection is not
established, because no IP address could be obtained (the IP address is shown as “169.254. ...” or “0.0.0.0”).
Enter the correct encryption key (WEP key) as described in 1 above, and reconnect.
