Recently, the network in my home is often interrupted, and it will be automatically connected after a few minutes, and the signal is not good, often only two signal lights, which directly affects the normal use.To make phone call for help, often wait 30 minutes can not be connected, have to ask for help again. Is this problem a TPG device or technical problem or a Modem problem? The problem, how to solve, please help. Thank you!
