3-Can You Disable WPS?
There are several different types of routers out there.
• Some routers don’t allow you to disable WPS, providing no option in their configuration interfaces to do so.
• Some routers provide an option to disable WPS, but this option does nothing and WPS is still enabled without your knowledge. In 2012, this flaw was found on “every Linksys and Cisco Valet wireless access point… tested.” [Source]
• Some routers will allow you to either disable or enable WPS, offering no choice of authentication methods.
• Some routers will allow you to disable PIN-based WPS authentication while still using push-button authentication.
• Some routers don’t support WPS at all. These are probably the most secure.
