Data services with legacy networks, or other cells that provide low data throughput, are disabled to accelerate reselection of a user equipment to cells that support higher bandwidths. The impaired cells are identified using techniques including determining whether SI2Quarter messaging is supported and comparing measured data throughput to the cell with a size of a transmission buffer in the user equipment.
