| [Internet] Zoom 5341J power levels Hello,
I am not sure how to determine if the numbers on my modem are considered "good." I am a Time Warner Cable customer and I have a Zoom 5341J cable modem. Above is some information related to my modem (obtained by logging into it). Please let me know if anything looks out of the ordinary, and if so, what I can do to try to fix it. Thank you, I appreciate it. |

If it's working, don't worry about it. |

Downstream numbers are okay. Ideal values are between -5 and +5dBmv with all channels within 3-5dBmV of each other, with the acceptable range being between -10 and +10dBmv. SNR above 36dBmV is good as well.
Your upstream is okay. You are on a 6.4Mhz 64QAM upstream at 52.8dBmV. The spec says 57dBmV is acceptable, but it is better to see it lower than 50dBmV to allow for power adjustments that are sometimes needed for things like thermal effects, ingress, etc, but it is more important to be below 50dBmV for when upstream bonding is turned up. 4x6.4Mhz 64QAM bonding requires power levels on each channel to be no more than 51dBmV (53 for S-CDMA). |
