hello again ;)

>Let me test here.  Fixing the speed is meaningless for hostap mode.
I don't want to use fixed speed exactly, but only try to find, where 
should be problem,
because if I have media adhoc, it's running well on 11MBPs

I'v used wget on linux client with IBM wifi card with Prism2.5 chipset  
(sorry i dont know exact numbers of this card)
oposite to one AP (FreeBSD 5.2-CURRENT #6: Thu Jan  8 17:29:53 CET 2004)
with the same IBM card  in hostap mode
wi1: <Intersil Prism2.5> mem 0xe6001000-0xe6001fff irq 10 at device 10.0 
on pci0
wi1: 802.11 address: 00:10:c6:18:52:8e
wi1: using RF:PRISM2.5 MAC:ISL3874A(Mini-PCI)
wi1: Intersil Firmware: Primary (1.1.1), Station (1.7.4)
wi1: 11b rates: 1Mbps 2Mbps 5.5Mbps 11Mbps
and i t look like this:

          => `/dev/null'

than I tried similar test with two BSD boxes, the same BSD as on the 
first test  now acts as client
with Zcon XI-626 card

wi2: 11b rates: 1Mbps 2Mbps 5.5Mbps 11Mbps

oposite to AP 5.1-RELEASE-p11 #0: Tue Jan  6 09:14:03 CET 2004
with the same Zcom card in hostap mode
map02# wget -O /dev/null
          => `/dev/null'

when I switched mode to adhoc between this boxes it runs on 11MBPs 
media: IEEE 802.11 Wireless Ethernet autoselect <adhoc> (DS/11Mbps <adhoc>)
wget test was

map02# wget -O /dev/null

there were no other clients associated on this APs  and both BSD boxes 
were not hardloaded
for better concept you can see our network structure there:
login: guest
passw: guest

the 5.2-CURRENT box is named "MAP02" , second one with 5.1-RELEASE-p11 
is "bluehillz" ,
linux client is not shown but is connected to MAP02

So it seems that is something wrong in hostap mode, because as I wrote  
in first email, on FBSD 4-x hostap mode work properly on 11MBps.
My friens who uses FBSD 5.1-REL on different geographical places has 
this problem too, so I think that problem is not caused by "local specifications"
Thanks for reply.
