Have done some new test.
This time the distance between AP and client is 4.45km.
Horrible results (see below)
On client I've a rssi of -75, on server too. Which is what is more or less

Same as in first email
6M: 1.5 Mbps
9M: 2.2 Mbps
12M: 2.7 Mbps (32%)
18M: 307-1000 Kbps
This results are again with fixed rates on both sites.
If I do not fix the rate the throughput is about 1.5 Mbps.
Of course 18M is already behing the quality for this speed.
But what could be the problem for this very low throughput?
There are no other 802.11a transmitter here so I "think" there is no noise.
We have no radar etc. here. Is this expected at this distance? I don't think
Distance setting is set to 6000m on both sites
Antenna diversity disabled, rx-tx antennas fixed.Countrycode=regdomain=0
Is there any other parameter which should be changed for outdoor usage?
I've also changed the channel. Nice thing ...
Setting channel 153 gives same rssi on client
Setting channel 157 gives -81 and than goes slowly to -83
(iwlist ath0 scan output)
Setting channel 165 gives -79 and than goes slowly to -88
Who is working with hostapd/wpa_supplicant in long distance links
with madwifi-ng? I use SR5 in AP, CM9 in client (and wrap boards as noted
Has anybody SR5 as master in long distance links. Have you too
such difference if you change the channel. What is the throughput, rssi at
which distance you get?
Is there there a problem if the interface is up and the channel is switched?
Thanks for any infos

Have you had this sort of thing working for any setup? Somehow I find it
to believe that 'hostapd+wpa_supplicant' would introduce problems,
client was attempting to reauthenticate repeatedly, or the ap was
the client, or some such scenario.
If that were true then you could monitor such traffic...
