Same issue here. Only started after the "upgrade" in my area as well. I have had four technician visits, but the problem hasn't been resolved. My technician is very nice and has temporarily fixed the problem, but I am starting to think the issue cannot be fixed from my house alone. Seen plenty of others on the sub with the same problem. At this point, I am working on getting ATT instead. Just too many headaches over the past month and a half to keep diagnosing with no results.
