Regression(?): InternetGetConnectedState returns TRUE always under Windows 11

Question

In my app I'm using InternetGetConnectedState to determine if the system is online.

I was using Windows 10 and it was always working fine.

Recently I've upgraded my machine to Windows 11 and found that it's not working anymore: it's returning TRUE always.

In its lpdwFlags parameter it returns 18, which means LAN (0x2) | RasInstalled (0x10).

I think this is a regression and it's related to Ras (I connect using Dial-up).

Two questions:

1. Is it really a bug, or me misusing this function in some way?
2. Is there a known workaround for my config?

Answer 1

As InternetGetConnectedState recommends,

use the INetworkListManager::GetConnectivity method instead.

There is a Microsoft sample NetworkListManager which is uploaded recently.
