If this helps anyone, it was my final re-work... (thanks Brian and John)
// using Android.Net
try
{
ConnectivityManager cm = (ConnectivityManager)GetSystemService(
Android.Content.Context.ConnectivityService );
NetworkInfo[] info = cm.GetAllNetworkInfo();
StringBuilder sb = new StringBuilder();
foreach( var n in info )
{
if( sb.Length > 0 )
sb.Append( "\n" );
sb.Append( n.TypeName + "\n" );
sb.Append( "IsAvailable: " + n.IsAvailable.ToString() + "\n"
);
sb.Append( "IsConnectedOrConnecting: " +
n.IsConnectedOrConnecting.ToString() + "\n" );
sb.Append( "IsConnected: " + n.IsConnected.ToString() + "\n"
);
sb.Append( "ExtraInfo: " + n.ExtraInfo + "\n" );
}
Utl.ShowMessage( sb.ToString() );
}
catch( Exception ex )
{
Utl.ShowException( "Net", ex );
}

Many thanks Brian - worked a treat
Just had to change Android.Content.Context.WifiService for
Android.Content.Context.ConnectivityService
In my old code and it would have worked The wonders of programming API's :-)
Thanks again John Murray

John
With the first bit, you are requesting a WifiManager, and are casting it to
a ConnectivityManager - if you want one of those, specify
Android.Content.Context.ConnectivityService
The second one, I'm not sure why you'd get a typecast problem
Code as below I'd expect to work, however I can't test it thanks to being
unable to successfully require the ACCESS_WIFI_STATE and
ACCESS_NETWORK_STATE permissions (as per other message in this list).
Covers wifi and mobile in the first case, just wifi in the second.
private string GetNetStateDescription(bool mobile) {
ConnectivityManager connectivityManager =
(ConnectivityManager)GetSystemService(Android.Content.Context.ConnectivitySe
rvice);
//Requires ACCESS_NETWORK_STATE and ACCESS_WIFI_STATE to avoid security
exception
NetworkInfo networkInfo =
connectivityManager.GetNetworkInfo(mobile ?
Android.Net.ConnectivityType.Mobile :
Android.Net.ConnectivityType.Wifi);
if (networkInfo.IsConnected)
return "Connected";
else if (networkInfo.IsConnectedOrConnecting)
return "Connecting";
else
return "Disconnected";
}
private string GetWiFiStateDescription() {
//Requires ACCESS_WIFI_STATE permission to avoid security exception
WifiManager wifiManager =
(WifiManager)GetSystemService(Android.Content.Context.WifiService);
switch (wifiManager.WifiState)
{
case WifiState.Disabled:
return "Disabled";
case WifiState.Disabling:
return "Disabling";
case WifiState.Enabled:
return "Enabled";
case WifiState.Enabling:
return "Enabling";
default:
return "Unknown";
}
}
