Netgear CM1100 speed and connectivity issues not getting Gig speed
I recently moved into a new townhome where Gig speed is offered. I purchased a Netgear CM1100 that is listed as a support gig speed modem. I have had service since 3/31/2020 and never once have I received more than 400-500mbs a second, and I experience random internet dropouts. Things I've done to troubleshoot:
1) Factory Reset Modem
2) Tried several different Cat5e and Cat6 cables
3) Tried two different Microsoft Surface Pro 5 PC's along with a Desktop PC (all of which I have confirmed are supporting 1gbs under the ethernet adapter settings
4) I've tried connecting the modem at the wall outlet, at the feed line coming into the house, and at the feed line outside the house coming from the street
5) I've tried going through the troubleshooting on the xfinity app as well
Nothing has worked. I have attached the modem data event log, but it won't let me attach the other data. I have tried going through the Xfinity chat but they are absolutely no help whatsoever. Please someone, help me get this solved.

we'd also want the modem connections page. it under the basic tab under cable connection.
this shows the line quality back to the isp.
what website are you using for testing on your desktop? (try speedtest.xfinity.com)
the desktop you're using, what specs is it? even though devices are labeled for gigabit, not all devices can fully saturate it. Make sure you're directly connected to the modem for testing. Reason why is we want to ensure it isn't the router slowing down the speed.
- I have screenshots of everything with the data connected at both the wall outlet and the line coming from the street to my house, but how do I upload multiple images on here? The PC's I've used are two different Microsoft Surface Pro 5's connected directly to the modem via a usb 3.0 gigabit ethernet adapter, and I also tried using the Surface Dock that fully supports gigabit ethernet. My desktop PC is one I custom built with a dual Gigabit ethernet adapter on the motherboard. All of these devices have been testing via directly plugging in several different Cat5e and Cat6 cables from the modem into the different PC's. Additionally, every time I tried a different PC or cable, I power cycled both the modem and the PC. I haven't even tried setting up my r9000 with it yet since I noticed I wasn't getting the speed I should from my modem. The websites I used are speedtest.net and speedtest.xfinity.com
