I talked to my cable TV repairmen recently, whom claimed this modem is on its last legs. It is about 3 years old. He claimed they are making modems cheaper and with less longevity than years ago and my modem life is about average, I rated it slightly higher than average reliability since it hads not failed yet. The speed is nothing to right home to mother about. It has done a serviceable job on light usage since our cable company instaled it with the internet connection in May 2006. It is a Atalantic scientific 2100 series. The repairmen could not necessarily suggest any choice better or worse when it fails completely in the next year. So my choice will be to either have my cable company replace for ~ $3 a month or just buy whatever is cheapest at my local electronic store when it fails. It would be nice if their was a truly supperior in reliability modem out their so I did not have to go through this hassle every 3-4 years. In short, Scientific Atlantic Modem ia average product in a mediocre modem marketplace.
