I have done the following that seems to help a
bit:<br>
<br>
iwconfig wlan0 channel X<br>

<div>hmm dont you have different bssids on your
channels? <br>
</div>
</div>

</div>
Yes, I do. I don't set the bssid, but just the essid and the
channels. <br>
</div>

<div><br>
</div>
<div>thats mostly fine (as long as u do not suffer from bssid
splits)</div>
<div>(thats why i would recommend setting bssid)</div>
</div>

fortunately I am not seeing bssid splits...<br>

<div>as setting the same bssid on different channels, is no good
idea, but afaic some people do it for simplicity,.. <br>

Why do you think is not a good idea? <br>

<div>p.s. regarding window, afair there are (besides message
interval) no (configuration) tuneables in actual linksensing</div>
</div>
<div><br>
</div>
<div>but how long does it need for you until a new link
is symmetric?</div>

It takes something like 35-40s (which leads to something like 40s
for a UDP connection to recover and 52s for a TCP connection). <br>
The idea was to tune the parameters to show that it was possible to
speed up the link establishment.<br>
