Methods and systems for fast recovery from serious differential interferences. An exemplary method includes the following steps: transmitting, by a transmitter to a transceiver, at a fixed data rate above 100 Mbps; receiving, by a receiver from the transceiver, an indication indicating that the transceiver is experiencing a serious interference; responsive to the indication, reducing the data rate at which the transmitter transmits; storing excess data that could not be sent during the period of the reduced data rate; and increasing, within less than 1 millisecond, the data rate at which the transmitter transmits to a level that enables it to transmit both the stored excess data and the ongoing data at the fixed data rate.
