access point broadcasting out of date SSIDs
I have been broadcating an SSID for a long time. At first it was protected via WPA2, then some letters that have been capitals are now small. Now I went back to the same SSID but with no password authentication. I have noticed some access points broadcasting these 3 SSIDs in the same time.
What would be the solution for them to erase old SSIDs from their configuration?
