I am currently developing an app targeted for the HP IPAQ 210. Part of this app requires the WLAN radio to be enabled/powered on to connect to a pre-configured access point. I'm currently using the IPAQ SDK (via P/Invoke) to enable the WLAN radio, but I'm having trouble reliably determining when the radio has established a connection with the preferred access point. I'm currently monitoring the Microsoft.WindowsMobile.Status.SystemState.WiFiStateConnected property, but I would prefer to subscribe to an event to be notified when the connection is established.
I've looked around a bit in the OpenNETCF library, and there seems to be promising things in 2.3, but we're stuck on 2.2 for the moment.
Is there a reliable way to determine the connection status?
It is ugly, and it is no event, but if all else fails, you could try and check the Wifi hardware state by reading it's registry key:
int key = (int)Registry.GetValue("HKEY_LOCAL_MACHINE\\System\\State\\Hardware", "WiFi", -1);
