freebsd stable - Mar 2005 - NDIS problems in 5.4-PREREALEASE

Hi all, I was using  NDIS for a (ath0) wifi 3Com OfficeConnect
Wireless 108Mbps 11g XJACK PC Card under 5.3-stable I upgraded my src
and hove now 5.4-PRERELEASE but now the card is not working well, when
I ping to my gateway I get very high response times and I start to
loose conection. the card acts like if there where a very poor signal,
any idea of what could it be wrong?

regards.

I see similar behaviour using a D-Link AirPlus DWL-520+ PCI.  It broke
completely after the changes to dev/if_ndis and compat/ndis that was
done about two weeks ago.

The patches around the 7:th of March (dev/if_ndis/if_ndis.c:1.83,
compat/ndis/kern_ndis.c:1.70, compat/ndis/subr_ntoskrnl.c:1.57) made
it start limping a bit, seemingly retrieving packets (as far as I can
determine) but having trouble sending any larger packets.  Sorry for
being vague here, I haven't been able to track it down better than
that.
