Hey,



Client [a] connects to access point [b], [b] then has a client which
connects to access point [c] which is connected to the webserver.
This would mean [c] only has one client being [b], [b]'s access point
has one client being [a], if you understand?

When running a download, [c]'s trafshow see's the data going to [b], [b]
then re-routes it to [a].

If you still unsure of what the network looks like, take a look at
http://www.unix.co.nz/~icepick/albanywireless.jpg . 
Noddy is a client to m0f0, m0f0 is then a client to Orcon.

Hi 
Your "problem" is accually not anything more than a fact, when dealing
with wireless connections all your wlan nodes share the available
bandwith. This means when you connect one host to AP this host will get
all avail bandwith and when you connect another host the AP will split
the bandwith in half(timeslots). So downloading a file from the
webbserver will cause 2x the traffic and therefore ~half the
transfer-speed.

I might add that I reasently did some testing of 802.11g wich is
54Mbit/s and the actual speed was ~14Mbit/s. The 14Mbit was achieved
with only one host connected and the distance of ~2m ;)

Connections are established over senaeo 200mw cards.

[a] client
[b] m0n0wall (have also tested with m0n0bsd)
[c] webserver.

[a] - [b] - [c] .... 

[a] can download from [b] at 500KB/s , 
[b] can download from [c] at 500KB/s , 
but 
[a] can only download from [c] at 150KB/s

This is over a pptp connection and not. Would seem that bsd is only
thinking about doing one thing at a time, waddup with that?

Barry
