After this recent discussion my cable phone modem went belly up. The technician arrived took on look and said, "That is an old modem and will need to be replaced". When I asked what the life expectancy of a cable modem was, he responded that in his experience they should last 3 to 5 years before needing to be replaced. He went on to say the technology is advancing fast enough that even if the modem continued to work, it should be replaced at least that often to keep up with the technology. While he was here he also upgraded my Cisco cable data modem and said I should plan on replacing it within another year or so. Charter is providing the modems and there is no charge for the upgrade so they aren't making any money on the upgrades.
