Lucent ORINOCO Mini PCI Card built-in Sony notebook computer

I have a Acccess Point, AirLAN by Krone and two its PCMCIA cards.
They are working correctly. I also have a Sony computer that has a
built-in Lucent ORINOCO Mini PCI Card. It works with Krone Access
Point intermittently and not at full speed and installed the latest
driver 7.64.1.316 from Microsoft.

If I do not use Krone PCMCIA cards, the Sony notebook connection to
the AP is more steady. When I use Krone PCMCIA card, the connection
of the Sony notebook may break from time to time. I need to power off
the AP and power it up again in order to resume the connection with
Sony computer. Can someone tell me the proper way to set up the third
party Wi-Fi PCMCIA card from the AP and any particular point I need to
pay attention to while setup.

Thanks,

Ray
