Minimum guaranteed wireless network bandwidth is provided to client network devices by monitoring the performance of network connections to identify client network devices experiencing network congestion. Congested network connections are then analyzed to determine the source of the network congestion. Depending upon the source of the network congestion, an embodiment of the invention may undertake steps to either improve the quality of the network connection or to mitigate the impact of this network connection on other network connections. High quality network connections may be allocated additional bandwidth, airtime, or other resources to reduce the network congestion. Low quality network connections are not allocated additional bandwidth, airtime, or other resources. Instead, the impact of this network connection on the other network connections is mitigated. Additionally, the low quality network connection may be transferred to another wireless networking device that may be able to provide a better quality network connection.

Airtime usage may be used as a factor in controlling network traffic flow to and from client devices via a wireless network interface. Received packets or other data are assigned to a quality of service profile. Additionally, a cost value for communicating the received data is determined at least in part based on an actual or estimated airtime usage for the received packet. The cost value is used to allocate wireless network airtime to data. The allocation of wireless network airtime may be varied dynamically based on operating conditions. The cost value may be based on factors including the airtime used to communicate data; whether the data is a retransmission; and wireless network overhead. The cost value of data may also be different depending on whether the data is being sent from a client device or to a client device.
