I have located your account and have begun runningdiagnostics on your equipment, and currently everything looks good. With regards to the 12.1.9 state code, the quality of the power source can cause intermittent connectivity and that state code. Is the HughesNet plugged into a surge protector? Temporarily plug the modem into a wall outlet and see if the 12.1.9 and disconnects go away. -Wade
