CM1000v2 Xfinity Gigspeed Issue

[torres7713]

Hi All,

I am having issues with my download speeds straight from the modem on my CM1000v2 device. I pay for the 1000mbps service but I am constantly only ever getting 600mbps down. I have an xfinity tech coming out tomorrow to check if the connection from the node to modem is the issue, but wondering if I provide the details from my modem here if anyone can help to identify any FW/SW issues. Thanks in advance for the help!

Modem: CM1000v2
FW version: V7.01.01 

HW version: 2.02

Are you speed testing with a wired PC connected directly to the back of the modem? 

Have the ISP check the signal and line quality UP to the modem. Be sure the ISP provisions the modem correctly.
Be sure there are no coax cable line splitters in the between the modem and ISP service box. 
Be sure your using good quality RG6 coax cable up to the modem. 
Be sure to power OFF the modem for 1 minute them back ON.

That is the plan.

Be sure there are no coax cable line splitters in the between the modem and ISP service box. 

None that I know of but will have the Tech confirm.

Be sure your using good quality RG6 coax cable up to the modem. 

Will have to ask the tech about this as the line they setup a few years back was theirs.

Be sure to power OFF the modem for 1 minute them back ON.

Done multiple times with no luck.

Thanks @FURRYe38

I am having the same issue. Called Xfinity and they mentioned issue with the modem. Called Netgear and they mentioned since more than 90 days need to buy $89 6 month tech support to get the software optimized. After purchasing $160 router getting shortchanged by Netgear like this. Expected better from them.

The power levels might be a little high and why do you have so high a number of correctables?

If youv'e got a tech coming out have him look at your signal levels very closely.
