摘要：A method and system are described for determining the reliability of thecommunications between a portable electronic device and an access point (AP) beforeassociating with the AP. In the described embodiments, a first probe request frame istransmitted to the AP at a first data rate, and a first probe response frame is receivedfrom the AP, wherein the first probe response frame is responsive to the first proberequest frame. Then, a second probe request frame is transmitted to the AP at a seconddata rate, wherein the first data rate is lower than the second data rate. Then, the
portable electronic device determines if a second probe response frame is received fromthe AP, wherein the second probe response frame is responsive to the second proberequest frame. The portable electronic device then determines the reliability of thecommunications between the portable electronic device and the AP.
