Wireless network device fingerprinting and identification using packet reception success probabilities

A non-transitory machine-readable storage medium encoded with instructions executable by a hardware processor of a computing component of an access point having a plurality of radio chains, the machine-readable storage medium comprising instructions to cause the hardware processor to:

• monitor traffic transmitted over a wireless network to a first client device to identify at least one value of at least one wireless network operational parameter;
• a label of the first client device being unknown;
• determine, for each at least one value of the at least one wireless network operational parameter, a respective probability of successful packet reception at the first client device;
• compare each probability to a data model representing probabilities of successful packet reception at each of a plurality of second client devices for each of a plurality of values of the wireless network operational parameter;
• the labels of the second client devices being known;
• and
• associate at least one of the labels of the second client devices with the first client device based on the compare.
