In this embodiment, based on the wireless connection of the AP220, the IxChariot server 210 is configured to control the IxChariot testing tool to establish a communication connection with the Endpoint tool, so as to perform a throughput test.
Since the throughput stability of the device is also an important indicator in an environment with poor network quality.
