In order to import and export Wi-Fi passwords, your computer must have a Wi-Fi adapter installed.

If you would like to import and export from the LastPass browser extension on Windows, you will need to re-run the LastPass Universal Installer.  This is due to the fact that we need to install a utility that requires administrator privileges in order to import and export Wi-Fi passwords.  You can re-run the LastPass Universal Installer from:

https://lastpass.com/installer/

You will also need to ensure you're running the binary version of the LastPass browser extension.  If you're not, in Firefox and Chrome, go to:

https://lastpass.com/dl/

In Safari and Opera, please see:
