In order to maintain performance during wireless communication, a transmitting electronic device may selectively perform a remedial action based on a monitored throughput. In particular, the transmitting electronic device may monitor communication with one or more receiving electronic devices, and may calculate a throughput metric based on the monitored communication. For example, the transmitting electronic device may monitor data rates, may receive feedback about the communication from at least one of the receiving electronic devices, and may determine an observed distribution of the data rates. Then, the transmitting electronic device may compare the throughput metric to a threshold value. If the throughput metric is less than the threshold value, the transmitting electronic device may perform the remedial action. This remedial action may include: denying subsequent association requests, discontinuing an existing association; and/or notifying a cellular-telephone network that the remedial action was needed.
