"nl80211: 'nl80211' generic netlink not found" when starting hostapd

I have been trying to get my Ubuntu 11.10 laptop to make an access point to connect my blackberry playbook . hostapd gave error Configuration file: ./hostapd-minimal.conf nl80211: 'nl80211' generic netlink not found nl80211 driver initialization failed. Is this a BCM4312 problem? Can madwifi , hostap create wifi acccess point for me? Connectify can do this on windows so is there no equivalent??
