4 Troubleshooting
If you encounter some problems installing the LevelOne WPC-0100 11Mbps Wireless
PCMCIA Adapter or you want to confirm whether your card is installed properly or not,
refer to below the procedure after you have installed the card.
4.1 Check the Various Properties of the Adapter
• Click the “ Control Panel “ and then the “ PC Card “. Check whether there is a
PCMCIA Adapter in one of the sockets or not.
• If you find an LevelOne 11Mbps Wireless PCMCIA Adapter in one of the sockets, it
means a Adapter is detected.
• If you see a Question-mark (?) or Exclamation-mark (!) in yellow, the resources are
conflicting.
• Right click “ My Computer “ and then select “ Properties “. Select the Device
Manager and click the Network Adapter. You will find the LevelOne WPC-0100
11Mbps Wireless PCMCIA Adapter if it is installed successfully.
• If you see the yellow sign, the resources are conflicting. Click “ PCMCIA Card
“ and then “ PCMCIA Card Service “, you can see the status of the PCMCIA
Adapter.
• If there are yellow signs either on the adapter or the PCMCIA card, please check
the followings:
1) Check if your Notebook supports 3.3V Card.
2) Check if your Notebook has a free IRQ. If not, make an IRQ free by assigning the
same IRQ to some devices.
3) Check that you have inserted the right card and have installed the proper driver.
