Methods, apparatus, and computer program products are disclosed for optimizing communications throughput in a wireless networking environment that supports a plurality of communications channel topologies that include identifying a plurality of clients having wireless network adapters supporting disparate channel bandwidths in the wireless networking environment, and periodically switching from one communications channel topology to another communications channel topology in dependence upon the supported channel bandwidths of the adapters of the identified clients. Optimizing communications throughput in a wireless networking environment that supports a plurality of communications channel topologies may also include identifying the supported channel bandwidths, quantifying current data traffic through each supported channel bandwidth, and switching from one communications channel topology that includes one supported channel bandwidth to another communications channel topology that includes another supported channel bandwidth at a time period dependent upon the quantified current data traffic.
