Asus Z390-E mobo, Win 10 v1903,

I'm using the onboard Intel WiFi and for the most part it works but every now and again I'll get 'No Internet' which isn't true. I only have to click a different link to prove that.

All drivers are up to date and the only reliable failure is when trying to install Malwarebytes. I downloaded the installer with the same connection but the installation itself requires a connection which always fails with 'No Internet' and proxy settings are cited as the source of the error, but I'm not using a proxy server.

Is this a win 10 issue or an Intel issue because I have another WiFi card I could put in.

Thanks - rev
