CM1150V dramatic slowdown, please help!
Two weeks ago I upgraded to Xfinity gigabit speed from 400Mbps, and for about a week I was getting speeds of 700-750Mbps. Around a week ago, I began to have disconnects where I would lose my Intern...
The .42 has been the most stable. However, once you update the firmware, you need to reset the router if you downgrade to the .42. That's had the best results for fixing issues with the R7000
Have the ISP check the singal line quality up to the modem.
Be sure there are no coax cable line splitters in between the ISP service box and the modem.

Around a week ago, I began to have disconnects where I would lose my Internet connection completely this was happening every day or every other day. Each time this happened I would unplug the CM1150v and the router (R7000), wait 5-7 minutes and then plug them back in and within a few minutes I’d be back online. Two days ago I had another disconnect and after I got the modem and router back I noticed my speeds had dropped dramatically to where I can only get 100-120Mbps.
I’ve tried:
Resetting the modem and router (unplugging them and plugging back in) dozens of times.
I’ve been on the phone with at least six different Comcast techs, each one would remotely reboot the cable modem and confirm that it’s being reprovisioned and being sent the correct bootfile for my speed tier (1000 Mpbs). I can also confirm the both the router and cable modem have very good airflow (ruling out any possibility of overheating).
The CM1150v firmware is 2.02.04 and I bought it in February of this year.
The R7000 firmware has been 1.0.9.88 and 1.0.9.42 (I was on 88, but I rolled back to 42 just in case that was the reason for the slowdown)
Please help, I have no idea what do at this point. Comcast has given up as well. They keep recommending I call Netgear support, but they are too expensive.
