Per our IRC conversation, it seems that this problem emerged for you
between 2.6.16 and 2.6.17. Please try using git-bisect to determine
exactly which patch caused this issue for you.
Thanks,
John

Just before teh network goes down i notice a slowdown, i investigated and i
discovered
that the card drops big (not _so_ big) packets:

Note: 192.168.0.2 is the Access point, so it is teh first node in the net.
This is another weird behaviour: small packets does arrive, big ones are
corrupt:
