CM1100 Throttle?
Alright, so this has been puzzling me for nearly 6 months now. And for the fifth time I had a Field Tech come to my home to test all of the cables I have already tested at least four times before. ...
The laptop I do have has issues with it's image. So I just went and looked in the Router's settings, disabled the only one I found to be enabled (Access Control), rebooted the router. Ran a Speedtest on my Desktop, getting roughly 800-900Mbps (Within tolerance I do believe.) Oddly, when running the built-in optional speed test on the R8000 itself, it only gets around 300Mbps. Is that normal?
You put what your speeds are coming out of the router but what speeds do you get with your pc directly connected to the modem?
And how are you testing? (sites/apps/etc)
We (The tech and I) tested the speeds from the coax coming out of the wall (Approximately 1398Mbps), his test device (Dunno what the testing device was, but it was similar to my VDV scout, barring likely more technical) couldn't pull data or anything from the modem, at all. However he could pull roughly 300Mbps from a LAN port on my Router.
My computer has similar results (Testing using Ookla (Speedtest.net), as mentioned above.) 200-300Mbps

My computer has similar results (Testing using Ookla (Speedtest.net), as mentioned above.) 200-300MbpsI'm wanting to know the speeds directly from the modem. The CM1100 has 2 ethernet ports but with the way xfinity provisions, only 1 device can be connected at a time. So unhook everything from the cm1100. power it off and wait 2 minutes. Then connect a pc/laptop (powered off) directly to port 1 on the modem. power on the modem and give it a couple minutes to fully boot. Then power on the pc.
Then test the speeds directly from the modem without a router connected.
What speeds do you get.
Did as you requested. No luck as my PC did NOT receive an IP, let alone acknowledged that there was a connection. The motherboard on my desktop is an Asus X99-E-10G WS.
The cable is brand new (Bought Yesterday, the 21st). Tested with my VDV tester. Verified good.
Don't see how it would yield a different result as the Tech's tester though with the previous modem (As mentioned before, we returned the last one, and got a new one of the same model).
Called Xfinity, got with someone who verified that the internal settings from their end are correct, they were. To be certain, the gentleman provided a new Boot file, and restarted the modem today.we're trying to figure out if its a modem issue or a router issue.
The R8000 has had issues with speeds 300+ if you're running qos, access control, traffic monitoring, or parental controls.
they'll all slow speeds down.
So we're getting you back to basics and want to ensure the modem is receiving full speeds. If it is, then we move onto the router.
do you have a different laptop/pc you can connect to the modem to test?
Again, ensure you've fully powered off the modem for at least 2 minutes with nothing connected to it.
