	Well ... apparently I should have suspected people to CC me
directly as I'm not on this list, but nonetheless I got some catching up
to do now :) (please CC me if you'd like a response within this next week
:>)

	I'm open to suggestions - don't get me wrong, but I'm 99.9% sure
that this is a WI driver issue with 5.x and not anything else. Others have
reported this same problem over the last 6 months and I have seen
absolutely no solutions their questions. Of course, it is very easy to say
that it could be a MTU setting or interference, but I have personally
tested over two dozen Prism 2.5 based cards using a variety of
configurations, changes in settings, you name it - I've tried it
(including trying to set the MTU lower).

	Something has changed since 4.9 that is causing hostap to run at
half pace while uploading to associated stations.

	I guess what I'd really love to see is someone looking into the
if_wi.c code and whatever else could be affecting this.. I'd be so bold as
to offer $$ for such a fix (I am that desperate). I have, myself, spent
countless hours, heck, weekends at a time, going through the code,
removing this, changing that - with no success.. Then again, I do not
claim to be a C programmer, much less someone that writes drivers.

	Just my two cents. My next step is to switch to Linux using the
hostapd project, which I really don't want to do :<..Though, it is my
understanding that OpenBSD doesn't have this problem - so I may try that
if there simply will be no resolution to this matter.

	Scott
