I was searching for my home WiFi AP (router's broken and am trying to fix it), when I found a WiFi access point that does not have any security but does have WPS enabled:
Thinking that it probably had a MAC address filter, I tried connecting to it. I was able to connect successfully and Internet worked.
WPS is weak by design, but having it enabled on a secured WiFi AP (such as the one above
NETGEAR_EXT) makes sense. Having it enabled on an unsecured AP where anyone can connect doesn't; it's like having a lock on a door, when the door is open already.
Does using WPS on an unsecured WiFi AP improve security. If so, how?
