A method and apparatus determine an adaptive data rate in a wireless communication network. The method can include: setting () a wireless network layer two negative acknowledgement message threshold based on an average fade duration over a frame time; receiving () a number of wireless network layer two negative acknowledgement messages at a device over a given period; comparing (), at the device, the number of wireless network layer two negative acknowledgement messages to the wireless network layer two negative acknowledgement message threshold; requesting () a higher data rate if the number of wireless network layer two negative acknowledgement messages is below the wireless network layer two negative acknowledgement message threshold; and requesting () a lower data rate if the number of wireless network layer two negative acknowledgement messages is above the wireless network layer two negative acknowledgement message threshold.
