for the first 3 month this modem work like a charm . after that , it start have problem . I replace the splitter and the cable to the modem with no luck . I go through all the reset procedure over and over again . there be no problem with the incoming cable signal . it be strong . I contact the manufacturer this morning and they inform I that they do not help private user\/owners ... only cable company who buy they product by the thousand . then she hang up on I . with -lrb- non -rrb- customer service like that , my recommendation be to look elsewhere . too bad ... I really like it those first 3 month .
