Error 1721 in Intel WiDi installation

Asked By 0 points N/A Posted on -

I have a Toshiba Satellite E205-S1904 laptop. My problem is regarding my Intel Wireless Display.

Recently it has stopped working. I attempted to set up the most recent edition of the driver ( but received an error stated below.

I have upgraded the HD graphics as well as WiFi compatibility drivers.

But it doesn’t help at all. Do you have any kind of solution for this?

I will suggest that you reinstall the driver, since it seems that the current Intel wireless drivers that you have on your system have some kind of a problem. Use the procedure below to reinstall the driver.

  • On your computer, click on start, and then go to My Computer.
  • Right click on My Computer.
  • Choose System Properties.
  • In the window that will open, you will need to look for Device Manager and click on it.
  • In the task manager window, you will need to look for the Intel wireless drivers from the list of drivers.
  • Right click on it and then choose uninstall.
  • After that you will need to restart your computer.
  • The driver will be reinstalled after you restart the computer.
