A method and computing device receives data packets on an upstream bonding group in full service mode, where the upstream bonding group includes a set of channels and each channel has a transmission quality. The method detects that a select channel in the set of channels is impaired when the transmission quality of the select channel is below a threshold value, and transitions the receiving of the data packets from full service mode to partial service mode by disabling data grant scheduling on the select channel. The method monitors the select channel using a spectrum management method while the receiving of the data packets is in partial service mode. The method transitions the receiving of the data packets from partial service mode to full service mode when a result from the spectrum management method indicates that the select channel can transmit data packets error free.
