The difference between wifi direct and ad-hoc mode is that wifi direct allows a pair of devices to negotiate a connection between themselves directly, rather than just having a standard ad-hoc network that many devices can connect to. In terms of how it behaves in practice, imagine a bluetooth connection running over a wifi connection at wifi speeds. Of course it doesn't support bluetooth protocols, but in terms of how you set up the connection it is similar. To clarify: this is a standard established by the wifi alliance, the same group in charge of all other wifi standards, including the ad-hoc network standard. >> This allows Wi-Fi Direct devices to directly transfer >> data between each other with greatly reduced setup.

Sorry for that. > Maybe I'm just commenting on something I don't have enough information on. WPS PIN mode is insecure, but although WIFI direct supports that the implementations I have seen all use the push-button mode, which as far as I am aware is reasonably secure. _______________________________________________ networkmanager-list mailing list [email protected] https://mail.gnome.org/mailman/listinfo/networkmanager-list
