Amp Cable Modem Question

I was getting some high upstream levels (52-53dbMv) with my cable modem plugged into the passive VOIP connection of my Comcast Amp. I moved the modem over to one of the powered ports and now I get the following power levels (48-49dbMv). Is there any problem with running the cable modem through one of the amps powered lines. As an FYI, this is one of these Commscope Amps that Xfinity installs that provides even output to all sources.Screen Shot 2020-07-08 at 5.32.13 PM.pngScreen Shot 2020-07-08 at 5.32.01 PM.pngScreen Shot 2020-07-08 at 5.38.16 PM.png

Can't see your pics. Since you are a new poster, they need to be approved by a Forum Admin. That could take some time. In the interim, you could try hosting them at one of those free third-party pic hosting sites like Imgur or Photobucket and post the link to them here.

 

Do you have their phone service as well ?

I do not have phone service, I just have internet through a modem I bought.

The stats look o/k as long as they remain stable (upstreams are close to being borderline).

No. It's fine. The bottom line is are you actually having any connectivity issues ? If not, let it ride.

Thanks. When I was running it through the VOIP connection on the amp, my US powerlevels were around 51 -52 for each channel. I just moved it to the powered connection and it brought it down to the stats you saw. We'll see how it goes.

As @EG said, let it ride. The voip port is more used for phone service, as it doesn’t lose signal if amp loses power. The way you moved it is used all the time.

Re: Amp Cable Modem Question

Thank you. One last quick question. The amp has MoCa and non-Moca amp'd lines. I have the modem on a non-MoCa line. Does it matter?

Re: Amp Cable Modem Question

The voip port is non moca, it would matter if you put an x1 box on the voip port it wouldn’t communicate. Same holds true if you put an X1 box before the amp
