I have a CM500V modem and Linksys mesh home wifi system and had no problems for a few years, all be it a few modem resets here and there. As of late last week it seems our internet drops off often daily and requires modem resets often. Had some windy weather come through so dispatched an Xfinity technician to come check connectivity at the pole to house. All is well. The tech stated the modem is "wearing out". Anyone hear of this? It has latest firmware, mesh wifinis up to date as well.
