There can be a number of causes for laggy or choppy connections when using Windows 10 Desktop Editon. Here are a few things you can try to improve this:

• Make sure your AirServer Windows 10 Desktop Edition is up-to-date by checking for updates in the Microsoft Store app.
• Your router might be running old firmware. Visit the router manufacturer’s website and download / install the latest firmware. In most cases, this resolves jitter and lag related issues.
• It is also possible that your connection cannot handle the bandwidth. Try connecting your computer to the network with an ethernet cable and check if the performance is better.
• Use iStumbler (Mac) or NetStumbler (PC) to see which Wi-Fi channels are in use around you, then configure your router to use a channel that is free. You should preferably also configure your router to only use Wi-Fi-n or Wi-Fi-ac (if supported).
• Make sure the device you want to mirror to AirServer is within sufficient range of your Wi-Fi.
• Switch on "Limit Mirroring Resolution to reduce bandwidth" in the Display tab of Advanced Settings. This will limit AirPlay and Google Cast to 720p30, while Miracast will be limited to 1080p30. This should improve performance in poor network conditions.
