But when I go to t-mobile to change the setting on my Gateway router, it says there are no webguards on it. I'm at my wit's end! Epson ST-C2100 and Home Internet Router TMO-G4AR not talking I have tried suggestions in other threads here. Nada All our devices (Roku, phones, windows computers) work great with the TMO, just not our Epson ST-C2100. Looking for success stories. Thanks all Dick
