CM1000 - Xfinity Gigabit tier - slow download speed
I've recently noticed slow download speeds on my Xfinity Gigabit Internet tier and I've been unable to determine what is causing the issue - I think it's on the Comcast end, but haven't ruled out tha...
same issue with two different netgear routers. help has been helpless
I have the CM1150V which adds telephony to the CM1000. I too am having issues with erratic download speeds. Channels 1-31 downstream are locked with frequency range from 477Mhz to 675Mhz. Channel 32 is not locked. Speeds range from 647mbps to 25mbps using a macbook pro via thunderbolt to cat8. Xfinity techs measured 947mbps via cat6 to their rasberry pi. I was told the Docsis 3.1 frequencuies are above 675Mhz, none of my channels are using these frequencies.
The upstream has channels 1-4 locked on, while 5-8 are not locked. Xfinity says they only have 4 upstream channels. Speeds are consistent around 32mbps to 41mbps.
There is only one firmware available for this model and it is only available for xfinity.
I ended up just bridge moding the comcast router and that solved all my problems at least for download speeds.
I don't have GB service from comcast, however as soon as I swapped out my comcast provided router with the CM1100, my download speeds dropped in half. I have the 200MB tier service from comcast and consistently obtained 180Mbps (speakeasy) download speeds via wireless or directly connected. Now I consistently get only 85Mbps. This has been going on since January and originally I thought I'd give it some time to obtain updates etc, however now I'm quite disapointed. What do you mean "bridge moding", do you think this would help for my situation? From what I initially read, it was primarily for gigabit service, which I don't have and ignored the instructions. Is this required to set up a local SAN/external HD for making my media available to my network? Any advice would be helpful, thanks in advance.
Cheers,

without bridge mode I was getting the comcast router and my router interfering with each others IP address assignments. i would recommend if you have a router from comcast, either use their router or put it in bridge mode and use your router.
