I've spent many hours trouble shooting this. Modem connects with internet access fine on Windows at the same location but not on my PI which is used for an industrial monitoring solution (signal strength is fine).
Can someone help please? I've tried everything I can think of including using alternatives such as using wvdial but get exactly the same result.
