1. A method of operating a computing device comprising a wireless network interface, the method comprising:

  • for each packet of a plurality of packets communicated over a channel, when performing error correction, computing an error metric by counting error corrections performed by the error correction to correct errors introduced by transmission;

    obtaining a signal strength indication indicating a signal strength of the channel;

    analyzing the error metric to determine whether the error metric exceeds an error metric threshold; and

    providing first logic that will be conditionally executed if determined that the error metric threshold is exceeded by the error metric, the first logic comprising;

    determining whether the signal strength indication and the error metric are both sufficiently high to cause a change in channel, and responsive to determining that the signal strength indication and the error metric are both sufficiently high, causing a change in channel from the channel to a new channel;

    providing second logic that will be conditionally executed if determined that the error metric threshold is not exceeded by the error metric, the second logic comprising;

    determining whether the signal strength indication is sufficiently high and whether the error metric is sufficiently low to initiate an adaptation process for communications over the channel, wherein the adaptation process comprises increasing a data rate for transmission of packets in the channel.
