it should be between +55 dBmV to 45 dBmV

please help.

Thanks

It's fine. Are you actually having any connectivity problems  ?

[rmaster]

yes I'm

[EG]

Please describe them.

What do the downstream power levels and the SNR's look like ?

[rmaster]

Downstream well within operating range, it is just upstream power level not to meeting the requirement

this what I own

Can we see the downstream stuff please ? As I stated, the upstream power is fine. 

Arris is wrong ! They have been passing the buck and have been conning people with that statement lately !! They are probably trying to cover up for the lawsuits against them because of their use of the horrible Puma 6 chipsets... Only the Comcast plant / engineering specs matter;

Specification Min Max
Downstream Power Level
Cable Modems -10dBmV +10dBmV
Gateways and EMTAs -7dBmV +7dBmV
Downstream Signal to Noise Ratio 35dB -
Upstream Power Level +35dBmV +50dBmV
Upstream Signal to Noise Ratio 31dB -
Upstream Receive Power -2dBmV
+2dBmV

You didn't describe your connectivity problem as was asked ?
