Abstract: Automating and extending path tracing through wireless links is provided by receiving a request to perform a network trace over a wireless link provided by an Access Point (AP) configured as a transparent forwarder between a trace source and a trace target; monitoring a trace packet from a first time of arrival at the AP, a first time of departure from the AP, a second time of arrival at the AP, and a second time of departure from the AP; monitoring a buffer status of the AP at the first time of arrival and the second time of arrival; and in response to identifying a network anomaly based on the trace packet and the buffer status, adjusting a network setting at the AP.
