Hello all!  So as not to inundate the entire list with a huge email, I have
put together a web page that
explains my situation and problem in detail.  Here is a quick summary:

Up until a few weeks ago, we had been using kernel version 2.4.18 and
CBQ.init to control bandwidth. I set that up quite a long time ago, and only
vaguely understood bandwidth control when I did, but it seemed to work well
enough. A few weeks ago, the hard drive began to fail in our master AP. I
had been working on designing its replacement anyway, so I was able to make
it limp along until I got 'Son of Master AP' up and running. The problem we
have now is that QOS is pretty crappy. I've read the LARTC HOWTO, and pretty
much the entire docum.org site. I feel like I have a relatively good handle
on the subject matter, but I'm not able to achieve good QOS. I'm mainly
looking for advice and input on how best to fairly share the available
bandwidth among the subscribers to our service. Ultimately we will want a
higher priority level for business clients, but that can wait until the
basics are under control. All details are available from

Not sure how the end of that email got mangled, but here's the corrected
URL.  Sorry for the problem!

Can you try to add "quantum 1500" or maybe 4000 to each class?

Trying 4000 right now, I'll try 1500 after I have a chance to see if 4000
makes any difference.  I have put new commands and stats (which I will
update periodically over the next few hours) at the
http://wireless.ccaonline.com/lartc/ site.  On initial examination it does
not seem to be making any significant difference.  I've still got very laggy
ping times, which I did not have when we were using CBQ.  During the HTB
research, I did discover that my CBQ setup was probably weird.  I had a
class for each user directly off the root, and the total rates FAR exceeded
the available bandwidth.  So from what I read it was probably pretty
whacked, but I always seemed to have stable pings under 10ms.  These are all
over the map (or graph as the case may be).

Anything else??

Thanks!!

just a red herring for you, ;-), but you may need to use some arbitrated
channel access mechanism for this many users off one AP, viz WiCCP,
otherwise channel contention will become an issue.  This will likely
cause high ping times.

Agreed, but just a few weeks ago, using CBQ, things were calm and stable.  I
can check to see if our overall data transfer is up from a month ago.
Thanks for the fish!

Can put your cbq setup on your web-server?  So we can compare....
