Abstract:
1. A method of operating a computing device with wireless network interface adapted to communicate over a channel, the method comprising: measuring errors associated with packets communicated in the channel; measuring received signal strength in the channel; determining a source of interference in response to a determination that the measured errors associated with packets communicated in the channel exceeds a first threshold in combination with the measured received signal strength in the channel exceeding a second threshold, wherein the first threshold is associated with a measure of errors and the second threshold is associated with a signal strength; when the measured received signal strength exceeds the first threshold for a period of time exceeding a third threshold, determining that the source of interference is a non-802.11 source of interference; and when the measured received signal strength exceeds the first threshold for a period of time not exceeding the third threshold, determining that the source of interference is an 802.11 source of interference.
