An electronic device that assesses communication performance is described. During operation, the electronic device receives information specifying a location in an environment. For example, the information may correspond to user-interface activity associated with a user interface. Notably, the user interface may include an augmented reality and the user-interface activity may include defining the location, such as by dropping a pin in the augmented reality. Then, the electronic device provides the information to an access point and/or a controller of the access point, where the location is within communication range of the access point. Next, the electronic device receives, from the access point and/or the controller, measurements of one or more communication performance metrics at or proximate to the location during a time interval. Moreover, the electronic device provides a graphical representation of the communication performance at or proximate to the location based at least in part on the measurements.

During operation, an electronic device receives a packet or a frame associated with a second electronic device, where the packet or the frame includes information specifying a factory reset command. For example, the second electronic device may be a dynamic host configuration protocol (DHCP) server or may perform functions of a DHCP server. Moreover, the packet or the frame may include an acknowledgment (ACK) in a discover, offer, request and acknowledgment (DORA) procedure, and the information may be included in an optionsubfield or an optionsubfield in the packet or the frame. In response to receiving the factory reset command, the electronic device performs a factory reset. Note that the factory reset may restore firmware in the electronic device to a factory-fresh version and a configuration of the electronic device to a factory-fresh state, may erase memory in the electronic device.

In response to receiving a primary wireless LAN connection request from a computing device, a wireless access point (WAP) establishes a temporary wireless LAN associated with a temporary service set identifier (SSID) of a computing device. WAP stores a computing device identifier of the computing device in association with the temporary SSID. WAP communicates to the computing device, a CAPTCHA challenge-response test requesting connection to the temporary wireless LAN. WAP awaits, for a timeout period, a temporary wireless LAN connection request by the computing device to communicate over the temporary wireless LAN. In response to receiving or failing to receive the temporary wireless LAN connection request from the computing device within a timeout period, WAP classifies the computing device as a human or machine user. WAP applies network policies to communications of the pending computing device over the primary wireless LAN based on the machine or human user classification.
