Claim:
1. A method for a wireless device to monitor Wi-Fi link quality, the method comprising: establishing a Wi-Fi link; monitoring RSSI of the Wi-Fi link; determining that RSSI of the Wi-Fi link has fallen below a first RSSI threshold based on monitoring RSSI of the Wi-Fi link; enabling monitoring a plurality of link quality metrics other than RSSI based on determining that RSSI of the Wi-Fi link fell below the first RSSI threshold; determining that a potential link failure event has occurred based on monitoring the plurality of link quality metrics; inducing traffic on the Wi-Fi link in response to determining that a potential link failure event has occurred based on monitoring the plurality of link quality metrics; determining a failure rate of the induced traffic; and triggering, if the failure rate of the induced traffic is higher than a failure rate threshold, a disconnection of the Wi-Fi link.
