WLAN setup in Windows XP Pro

Archived from groups: microsoft.public.windows.networking.wireless (More info?)

Can someone explain to me the function of "Enable IEEE 802.1x authentication
for this network and EAP type: Smart Card or other Certificate" in wireless
network properties. I found in some notebook computers that enabling it
will cause intermittent connection dropout and I have to disable it to have
a steady connection. Your advice is highly appreciated.

Thanks,

Ray
