There can be many causes for lag or a choppy connection, but here are a few things you can try:

 

  • 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.
  • We highly recommend using AirServer for Windows 10 Desktop Edition if you are using Windows10. It can be downloaded by following the link or by finding it on the Windows Store
  • Try changing the optimization (under the mirroring tab) to 720p and mirror again. If AirServer is projecting on a display which is 1080p (or larger), and mirroring optimization is set for "Any Device - Recommended," then AirServer will automatically negotiate the best possible mirroring resolution for 1080p, which can cause slowness.
  • For even better performance, but lower quality, select the "slow network" option under the mirroring tab. Then mirror again.
  • Use iStumbler (Mac) or NetStumbler (PC) to see which WiFi channels are in use around you, then configure your router to use a channel which is free. You should preferably also configure your router to only use WiFi-n or WiFi-ac (if supported).
  • Make sure the device you want to mirror to AirServer is within sufficient range of your WiFi.
