Claim:
A network appliance comprising: a first media access controller configured to associate with a first wireless device, the first media access controller including a first transmit queue configured to store one or more data packets to be transmitted to the first wireless device; a second media access controller configured to associate with a second wireless device, the second media access controller including a second transmit queue configured to store one or more data packets to be transmitted to the second wireless device; a baseband processor in communication with each of the first media access controller and the second media access controller; and an arbitration module configured to: arbitrate access of (i) the first media access controller and (ii) the second media access controller to the baseband processor based on whether the first transmit queue and the second transmit queue have any data packets to be respectively transmitted to the first wireless device and the second wireless device, and in response to both the first transmit queue and the second transmit queue simultaneously having one or more data packets to be respectively transmitted to the first wireless device and the second wireless device, instruct either (i) the first media access controller to flush any data packets stored in the first transmit queue or (ii) the second media access controller to flush any data packets stored in the second transmit queue so that transmission of a flushed data packet can be re-tried.
