Hi wadedf,
Thank you for testing that out for me. We will need to get you a replacement modem for this particular issue. I will create an order for a free replacement which should arrive to you in just a couple of days. It will have a pre-paid label enclosed which you will need to use to ship the old one back. The swap is just a matter of moving your cables from the old modem to the new one. Let me know if you have any questions or concerns and I'll be happy to help!
Thanks,
Amanda
