      Description

      [I'm affected by this on Windows, this could apply on other environments as well]
      The windows bearer implementation answers true to requiresPolling and hence QNetworkConfigurationManager polls Windows for WiFi networks every 10 seconds. This causes network traffic to stop for a small amount of time, causing problems with any realtime applications like VoIP or Multiplayer games (our usecase).
      A fix would be to have an API to disable this polling.
