A recent scheme for perfect routing of quantum states through regular networks requires application of global control at regular intervals of time. We study the effect of stochastic noise in this control and find that the scheme is robust for reasonable values of disorder. Both un-correlated and correlated noise in the external control are studied and it is remarkably found that the efficiency of the protocol is much higher in presence of correlated noise.
