Abstract: In one aspect, a method is described. The method includes detecting a first data packet transmitted through a wide area network (WAN), the first packet representing media presented at a client device of a plurality of client devices at a media exposure measurement location, each client device having a respective device identifier; detecting, within a monitoring interval, one or more second data packets transmitted through a local area network (LAN), each of the one or more second packets specifying a candidate device identifier, where the monitoring interval comprises a time window from the detection of the first packet; generating a score for each candidate device identifier based on a number of the second packets detected within the monitoring interval; based on the score, selecting, from the candidate device identifiers, a target device identifier; and storing data correlating the first packet with the target device identifier.

Abstract: Example methods and apparatus to recognize metered devices connected to proprietary WiFi extenders are disclosed herein. In some examples, a first device comprising at least one memory including a table, and at least one processor to broadcast a first message to a network extender, the first message including a first address associated with a second device and a message identifier, identify, in response to obtaining a second message including the message identifier, a second address embedded on a data link layer of the second message, and store the second address in the table in association with the second device.
