    Bought the modem and used some best buy rewards. The unit sat for a few months before I had time to find a new mesh router and switch to the new equipment. Worked great for a week then the ethernet port completely went dead (no lights). Multiple calls with ISP and motorola before this was discovered. I was on hold for hours with motorola then got discounted without any support. Took weeks to get a new unit and that was refurbished one not new. Customer service is horrible. Never again.
