We have 2 SSID here, "public" and "private". There is a password on each.
But someone told me he can't see the "public" SSID, he sees "public2" and the "public" 's password doesn't work on it. So he can't connect.
Why does it create another SSID like that? And what I have to do to connect him to "public"?
You can always run Netspot, Acrylic, InSSIDer or else to see the BSSID of the network that is seen by your users to have better view on that (whether this wireless network is really yours or your neighbor's).
