receiving, from a network access device as part of establishing a data connection with the network access device, a first frame indicating that a protected frame feature is to be used to communicate information regarding a power mode change, the first frame indicating that the network access device supports the protected frame feature and discards a frame that is sent to indicate the power mode change and that does not conform with the protected frame feature;
sending, to the network access device as part of establishing the data connection, a second frame indicating that the device is to use the protected frame feature;
sending, to the network access device after the second frame is sent, a third frame indicating a first change to a power mode of the device and conforming with the protected frame feature;
sending, to the network access device after the third frame is sent, a fourth frame indicating a second change to the power mode and conforming with the protected frame feature; and
receiving, from the network access device after the fourth frame is sent, a fifth frame that includes data buffered by the network access device.
