Oups ...
Ok I found the message on ath9k-devel.
Thanks a lot !
I was not sure if the problem is in hostapd, driver or hardware but 
finally it is in firmware :) ...
Not easy ...

So does somebody can help me to choose a wifi dongle able to manage more 
simultaneous stations ?
I see a lot of users reporting reference of hardware compatible with 
hostapd, but the number of allowed workstation is never reported.
And this kind of information is not in specs.
(for my dongle, the specs did not event mention ability to use Master 
Mode ...)

thanks again ...


Mike
