Same ** here started around the same time, have spent countless hours on the phone on hold i think around 14 times now, have had several techs come out,filed a complaint with the BBB (do that if you want attention from them) after all said an done they said the problem is my end,even tho we went through 5 of their own modems several of the service peoples modems and bought a $200 one myself instead of using their **,and they where still unable to fix it so closed the complain saying the problem is on my end even after all of their own people they sent out saying the issue was on their end lol, do yourself a favor and see if you have the option of switching to Fiber with someone else im switching to AT&T next month at my new house its half as much money ($70 instead of Cox $170 for unlimited) has unlimited usage and is a 1000 Down and Up.
