I've read there's fixes for the hostap drivers to mitigate this, but despite
a few hours digging for them, I haven't found them. Someone with more
knowledge could probably locate tthem more easily and then hopefully patch
the m0n0wall hostap sources...

However, realistically your best bet is to run a separate AP. Reading
between the lines, I'm guessing this might not be possible for you?  (Are
you deploying 500000 units of this?  Wow!).

Unless someone can locate the patches in your timeframe (sounds short and
hence unlikely), you might have to go to Pebble (www.nycwireless.net/pebble)
or wisp-dist or similar - as we've been forced to do for a couple of our
installs where m0n0wall was otherwise perfect :-(.

Aspiring contributors: if you can find the right hostap patch, you'd be
doing a great many people a real favor in the m0n0wall community!

cheers, michael

Subject: [m0n0wall-dev] powersaving mode (on clients) causing lots of
headaches


Hi,

I finally got my senao ext2 card in (200mw prism), upgraded firmware
to 1.1.1/1.5.6. I spent all day messing with it thinking there was a
major problem. Let me explain.

I have a 12" pb I normally use for testing. It was working flawlessly
with the m0n0wall machine/wireless. Then, I whipped out a toshiba
laptop w/ integrated wireless, intel mini-pci something or another. I'd
try to load things, it barely worked sometimes, other times nothing
worked at all. I spent hours changing firmware revisions etc trying to
find the problem. Well, unfortunately searching on this list is an
absolute joke, so that was no help, but I saw something in google
concerning power saving for an unrelated issue. I said what the heck,
and disabled power saving mode on the card in the laptop. Walla,
everything is perfect again. The thing is, with powersaving mode on,
there was no trouble with my other wireless network (mish mash of
airport extreme base stations, various cisco 350s and so forth). It
only has problems with m0n0wall when powersaving is enabled. This is a
serious issue for me because when I've got 500,000 people attempting to
login all over this state, and all those with centrino laptops and
powersaving mode on by default can't connect, there is a problem.
Unfortunately putting a page on the captive portal explaining it
doesn't work, since 99% of the time it can't even be loaded w/
powersaving mode on. I suspect it's some issue with the freebsd
wireless drivers, has anybody come up with a fix for this yet? I'm not
in-the-know when it comes to writing drivers, so I really can't assist.
:/

I really appreciate your time/input/suggestions, this is a show-stopper
for me until I can get it resolved.

Thank you as always,
David

PS - I read somewhere 1.5.6 is the station firmware to use on fbsd 4.x,
the others only work well with 5.x+. I've also read wireless got a nice
overhaul in 5.x, and I suspect this issue was probably one of the
things fixed. Maybe it's worth looking into? I saw a thread on 5.x
here, and read some people had troubles. I've been running 5.x for over
a year now on a few of my database servers which have constant 4+ load
and no troubles. I guess it just depends on your setup. :) 5.x stable
is on the way for production use though, so it might be a good option.
Or, at the least, a backport of fixes to the wireless side of things.
Also, ipf rocks, ipnat rocks, transparent redirection etc. Really nice
setup. :) At least worth looking into (for the devs).

Realized this belonged on the -dev list so here it is. Sorry about
that. :)
