High Upstream Power Ratios with known ISP Network Node Utilization Problems

[ReppuKishin]

In a nutshell, my ISP (TimeWarner Cable), after some hard-fought phonecalls, acknowledged and identified a problem with their networking node and the utilization of it's channels within my neighborhood (And city as a whole). Whenever -that- will be fixed is a question nobody can answer.

However, my limited knowledge of channel pathing has me asking; would this be causing my Upload power levels to be spiked so high? If not, are there any logical steps I can do to bring them back down a bit?

This is a DOSCIS 2.0 modem (I plan to upgrade it once the networking node errors are repaired, since they're monitoring the devices of the neighborhood and a swap would be disruptive, and the replacement not currently being a 3-in-1 pile of garbage), to give an idea of 'acceptable' power levels:

Downstream:
Channel ID: 7
Frequency: 621.000 MHz
Power: -9 dBmV
Signal to Noise Ratio: 36 dB

Upstream:
Channel ID: 4
Frequency: 37.000 MHz
Power: 55 dBmV
Upstream Data Rate: 2560 Ksymbol/second
Modulation: QAM-16

The Downstream is usually closer to -7/-8, and the Upstream -usually- sits at 52, and is usually at a higher Data Rate (I imagine it went down to 2560/QAM-16 because of power levels).

I have heard of the use of boosters (IE: http://www.amazon.com/Motorola-Signal-Booster-1-Port-Amplifier/dp/B003T2RY7I/ref=sr_1_1?ie=UTF8&qid=1456856622&sr=8-1&keywords=Active+Return+Cable+Modem+Boost ) to assist. Possibly just having all the (old) wiring replaced finally (I think the wiring of the house is on the older side of acceptable + I question what they were thinking running it from tap to house). If there are any additional splitters being used, they're likely inside the drywall, meaning it'd be more... affordable/less insane to just run a new cable from the tap to the modem.

Any help would be appreciated.

Higher power and a lower data rate can indicate a possible line issue. As for whether that is connected to the ongoing issue your ISP is monitoring, that's hard to say. I'd keep checking those readings and see if those readings improve once the ISP fixes their node issue.

Noted. I'll likely wait to do any hardware or wiring changes until I'm given an update on the networking node issue. I've got some Lead 3 Technicians keeping me up to date so we'll see if they actually do work on it or not. If not, well, hah.
