Reducing re-association time for STA connected to AP

A method and apparatus for re-associating a station (STA) to an access point (AP). The STA sends a re-association request to the AP to initiate a re-association process with the AP. The re-association request indicates that a handshake operation is to be bypassed during the re-association process. The STA receives a re-association response from the AP in response to the re-association request and, upon receiving the re-association response, enables data communications with the AP using a set of preexisting cryptographic keys. For example, the set of preexisting cryptographic keys may be negotiated with the AP during at least one of a prior association process or a prior re-association process.
