Make sure the Firewall on PC doesn’t block LetsView.
To enable it, you need to open “Control Panel” > “System and Security” > “Windows Firewall” > “Allow an app or feature through Windows Firewall”, then you can find LetsView under “Allowed apps and features”. Check “Private” and “Public” to allow this app to communicate through Windows Firewall.


Check the antivirus software and Bonjour Service

    1. Make sure the antivirus program doesn’t block LetsView. You can disable the antivirus software first and retry.
    2. If you are using an iPhone or iPad, please make sure that iTunes is installed on your PC and then examine the Task Manager to see if there is the service available. Hold down “Ctrl + Alt + Delete” on the keyboard or just right-click on the taskbar to open the Task Manager. Check Bonjour Service within “Services”. If it’s running, you need to right-click it and select “Restart” to retry. If it is stopped, you need to right-click to enable it. If there’s no Bonjour Service under “Services”, you need to download it on your PC manually. Just make sure the setup package is downloaded under the LetsView folder.Bonjour service
    3. Check if the mirroring service is enabled by clicking on “Settings” >”Mirroring service”.setting-letsview

Check the router and virtual machine

  1. If you are using a public or company WiFi and the “AP Isolation” is enabled or the router blocks our ports, you need to consult the technicians of your company to fix the issue.
  2. If you are running LetsView on a virtual machine, change the network sharing mode to “Bridged”.

Check Network Speed and Profile

Check Network Speed:

Click the “Mirroring detection” button in the upper right corner of LetsView and check the current network speed (there may be other applications such as web pages occupying the network speed in the process, the test result is for reference only). If you need a better mirroring experience, you can contact the network operator to increase the bandwidth or change to the 5G router.

Check Network Profile:

  1. Right click the network icon and select Open Network and Internet settings.network settings
  2. Click on Properties.properties
  3. Select Public.public network
