Comcast XFINITY → [Connectivity] Modem Stats

Hi,

I've been experiencing intermittent connectivity problems for months.
My line has no splitters or TV's connected to it. The cable drop is connected directly to my modem.

Downstream:

Power Level: Signal to Noise Ratio:
Channel 1: -1.6 dBmV 40.1 dB
Channel 2: -1.4 dBmV 40.4 dB
Channel 3: -2.3 dBmV 40.3 dB
Channel 4: -4.3 dBmV 39.3 dB
Channel 5: -4.2 dBmV 37.8 dB
Channel 6: -4.7 dBmV 38.5 dB
Channel 7: -3.6 dBmV 39.0 dB
Channel 8: -3.6 dBmV 39.5 dB

UPSTREAM:
Power Level:
Channel 1: 39.5 dBmV
Channel 2: 38.0 dBmV
Channel 3: 41.0 dBmV
Channel 4: 0.0 dBmV

As far as I can tell, these are pretty bad stats, right?

Those are great stats.

If there are no splitters like the OP says, then the modems Downstream receive is a little low unless the OP has a 200ft RG6 drop to his house.

Say the tap is putting out 13dBmV of signal and the drop is 100ft. The OP should have about 7dBmV at the ground block. Add another 50ft of cable to his modem, he should have about 4dBmV at the modem. So either the signal is low out of his tap or his drop is bad. If the OP is at the end of the line at an 8 Value tap, then his levels at the modem are right, but his TX is too high. Which also indicates bad levels at the tap or a bad drop.

But every cable plant is setup a little differently and we don't know the layout/specs of the cable plant at the OP's neighborhood

The SNR is good.

So the moral of the story is that the OP should set up a trouble call either way.

They are in acceptable ranges but not great.

1) Downstream has 3.3 dBmV spread
2) SNR has 2.6 dB spread
3) Upstream has 3 dBmV spread

Thanks for the replies. I had a visit set up 2 weeks ago. I stayed home all day, but the tech never showed. Didn't even bother calling.
That's when I decided to go out my self and connect the cable line directly to my modem (I was losing internet for multiple hours/day).
The rep in the direct forum setup the initial tech visit. I was hoping that he would help set up a second visit, but I haven't heard from him in over a week now.
