Abstract
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 option 43 subfield or an option 52 subfield 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.
