1. A computer-implemented method of operating a wireless network access point of a wireless network, the method comprising:
wirelessly exchanging management frames with a device to attach the device to the access point in order to establish:
a wireless downlink data communication channel from the access point to the device, and
a wireless uplink data communication channel from the device to the access point;
responsive to establishing the wireless downlink communication channel and the wireless uplink data communication channel thereto, performing a test of the wireless downlink communication channel and the wireless uplink data communication channel at a data link layer, the test including:
transmitting a test frame to the device on the wireless downlink data communication channel, the test frame:
having a length greater than each of the management frames,
including a sequence of test data bits, and
being configured to require a mirror response comprising the sequence of test data bits;
monitoring for receipt of the mirror response on the wireless uplink data communication channel; and
determining whether the test is passed or failed, wherein the test is only passed if the mirror response is received on the wireless uplink data communication channel.
