Wired and wireless communication networks can be subject to noise and interference resulting data corruption. In a communication system comprising a first network device and a second network device, the first and the second network devices can be configured for optimizing the data rate of the communication system. On receiving a multi-band signal at the first network device from the second network device during a channel adaptation mode, the multi-band signal can be split into a plurality of independent frequency band signals. A performance measurement of a first of the plurality of frequency band signals corresponding to a lowest frequency band signal can be calculated. Communication parameters can be determined for each of the plurality of frequency band signals based on the performance measurement of the first of the plurality of frequency band signals. The communication parameters can be provided from the first network device to the second network device.
