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
First, thanks for taking the time to help out, I very much appreciate it.
Ok, so I guess it's not my Cable Modem, I did a direct connection Computer to Modem, and got 905Mbps/41Mbps (download/upload)
I assume it's the router then?
Anyway here are the screen shots of my CM1150v Connections page and of Speednet (my computer direct to the CM)

Question is, what's the best way to troubleshoot the Router (R7000) Firmware 1.0.9.42 ?
FYI, I was have the same slowdown issue with the latest firmware (1.0.9.88)
It would be the router.
The R7000 is a semi-older generation router. It may not support 900Mbps on the WAN to LAN which needs NAT hardware accelleration or Cut-Through technology support to achive those speeds. You may need a more newer generation router. The R7800 I have supports 900Mbps on the WAN to LAN. I presume most models after this and the newer RAX series do this as well. The XR450/500 gaming routers also support 900Mbps.
Try a factory reset on the R7000 and setup from scratch. Be sure to not enable any QoS, Traffic meter or Acess controls. With 1 wired PC connected to the router, speed test after the setup completes. Be sure no wiress devices are connected here as well.
If the speed doesn't go up, then the router is probably not supportive of near 900Mbp speeds.
If you have a Gb LAN switch and two wired Windows PC you can test your R7000 out for youself using this tool:
