Wouldn't the MAC address be exposed even if WPA is in use?

If not, how do the encrypted packets get routed to the correct radio?


MAC filtering is useful to prevent casual or unintentional use of an
otherwise open network. Much the same way that turning off broadcast of
the network ID discourages casual use, but has no real impact on
security. But both can have some value in slightly raising the bar
against attacks, in the same way as having ssh listen on an alternate
port does.
