Examples relate to managing network traffic. In one example, a computing device may: receive voice network traffic from each of a plurality of voice clients; enqueue the received voice network traffic into a voice Wi-Fi Multimedia (WMM) queue; determine a measure of WMM queue utilization based on data queued in the voice WMM queue; determine a measure of radio congestion for a surrounding area; and determine, based on the measure of WMM queue utilization and the measure of radio congestion, to: stop prioritization of newly received voice traffic from new voice clients, or transition at least one of the plurality of voice clients to a neighboring computing device.
