Hi all, I have installed the Hostap driver in my computer,
Im working with PC Card Adapter PC750 and a 11Mbps wireless LAN PC card
but I have this error message, maybe the configuration is not correct,
after I connect the my PC card I have more or less 5 minutes to work but
after, keyboard and mouse are blocked. If someone has the same problem or
knows how to fix it, please help me.

Thank you very much.
