A wireless access point can identify a group of service providers that can provide access for respective subscriber devices. The wireless access point can periodically monitor its network traffic load. In response to determining that the amount of the network traffic load is above a threshold amount, the wireless access point selects one or more service providers from the group, and impedes use of each of the selected one or more service providers from the wireless access point by one or more additional subscriber devices that have not yet connected to the wireless access point.
