I have an application where the AP needs to broadcast information freely
to clients without any pre-association. I'd use the beacons, but the
wifi chips make that difficult.
I need to broadcast without encryption, but I don't want to have an open
access point that could be a security problem. So I want to prevent
clients from forming an association. Rather the client just sniffs for
the right broadcast packet to get the information they need. This is
somewhat the opposite problem from those who want encryption with no
password.
Is it sufficient to set up hostapd with no WPA, but not run dnsmasq, and
disallow routing at the AP? Or is there a clean way to set up the
hostapd.conf to not encrypt but disallow associations, short of
modifying the hostapd source code to disallow associations?
Thanks,
Mary Ann
