Hi,=0A=0ASa thing has changed .... 2 day ago I have tried what happen if I =
try to use ndis on my wifi card (windows drivers)...so I created drivers wi=
th ndis and...it was working a better than native freebsd ath driver so I w=
as using till today...today I have updated to FreeBSD 6.2 PRERELEASE (can't=
cvs to main server where 6.2 RELEASE is) newest version build world, kerne=
l (removed ath driver from kernel ) and try to use once again ath driver bu=
t now as a module....and now it is working a better than it was working day=
s before...it si working like ndis but a little little slower...=0A=0A$ifco=
