The laptop is able to connect to 99% of the worlds AP's, maybe it is a
common practise to allow graceful degradation if some station is
misbehaving a little bit?

I don't think that Asus cares much about how a "bug" in an old EeePC
1000HE, so if you want to punish misbehaving stations in hostapd, I
guess I must go back to my old setup? Are you sure the error is not in
my conf, or could there be some setting in the conf to allow the EeePC
to work?

I would much rather use this new atheros card and hostapd on my home
server than go back to using my old external Buffalo Airstation G54 as
the WLAN AP...
