Orinoco card not working

Today morning - no network. Started to investigate, PC had wireless network, after some trying also Airport on mac woke up, but my main network interface on mac, Orinoco card connected to antenna and remote 3Mb external link, was down.
System log said:
May 4 07:53:13 localhost kernel: org_noncontiguous_WirelessDriver: _wi_receivePacket(), bad status

I am using drivers from Sourceforge.net.
So I uninstalled drivers and reinstalled them again - now this PCMCI card is working again. What was the problem???
