Hi Keashdoc -

Perhaps the InternetGetConnectedState() API function might help, see also InternetGetConnectedStateEx():

#define INTERNET_CONNECTION_MODEM			1
#define INTERNET_CONNECTION_LAN				2
#define INTERNET_CONNECTION_PROXY			4
#define INTERNET_CONNECTION_MODEM_BUSY		8
#define INTERNET_RAS_INSTALLED				16
#define INTERNET_CONNECTION_OFFLINE			32
#define INTERNET_CONNECTION_CONFIGURED		64

CLEAR

LOCAL lnFlag
lnFlag = 0

DECLARE Integer InternetGetConnectedState ;
	IN wininet.dll ;
	Integer@, ;
	Integer

IF InternetGetConnectedState(@lnFlag,0) = 0
	? "No connection at all"
ELSE
	IF BITOR(m.lnFlag, INTERNET_CONNECTION_MODEM) = m.lnFlag
		? "Modem connection available"
	ENDIF
	IF BITOR(m.lnFlag, INTERNET_CONNECTION_LAN) = m.lnFlag
		? "LAN connection available"
	ENDIF
	IF BITOR(m.lnFlag, INTERNET_CONNECTION_OFFLINE) = m.lnFlag
		? "Connection is off-line"
	ENDIF
ENDIF
