Solutions
Check the Wireless LAN Adapter icon in the Windows
control panel and make sure the PC Card type can be
recognized.
The Windows Add Hardware Wizard was unable to locate
the Wireless LAN Adapter drivers. You may have had no CD
or the wrong CD inserted in the drive, or the 3Com CD may
not have been ready when the wizard looked for the drivers.
Remove the unknown device and repeat the installation
procedure. Make sure you insert the 3Com CD when the
installation calls for it and that you wait for it to come up to
speed in the drive.
A resource conflict may exist. Use the Device Manager to
resolve resource conflicts. Select System from the Control
Panel, and then click the Device Manager tab.
If you are using a 3CRWE62092B PC Card, make sure the
XJACK antenna attached to the end of the card is extended.
Try reorienting the antenna. For best use of the antenna:
Keep the area around the antenna clear from materials
n
that could block radio transmission, such as metal
objects, electronic devices, and cordless telephones.
If the signal is weak, change the direction of the antenna
n
slightly.
If necessary, move your computer a few inches to find a
n
better signal.
If you are using a PC Card, make sure the card is properly
inserted in the slot.
If you are using a PC Card, make sure PCMCIA support is
installed.
Check whether a card is already in use.
Windows XP, 2000, Me, and 98 SE: Check whether the
computer has a Plug-and-Play BIOS.
Log out and log in again, or restart the computer to restore
the connections.
