Or it may be that your SNR Margin is normally very stable and you want to see if by bringing your Target SNR down you can perhaps get a bit more speed. The slider is not entirely accurate, and because each line is different then you will have to experiment.
But as a guide Rate your ISP. Using the DMT Tool v8. Running DMT Download and unzip into a folder. Click DMT. Your Line stats DMT shows you your current line stats from your router. Bit rate - Your sync or connection speed.
DC is generally ok but not AC. Code is no closer than 6 inches and for good reason. There is a thing called inductance which can not only cause issues with signal but be potentially deadly. Many techs understand when running underground not to run cable with power but then fail to do this in practice within a persons dwelling.
I've seen cable run with house wiring many times and have had to reroute the wires safely away from power. The biggest issue with this is because traditionally cable techs weren't required to get low voltage licenses and don't understand electronic theory. There are set practices and codes that have to be observed when your a low voltage tech.
Your work is inspected by Labor and Industries and if it fails -your in trouble or have to redo everything. When I stepped into the world of Broadband communications I was stunned to see just how badly they ignored theory and NEC codes. Not all of course but too many don't understand the reasons behind why certain codes are enforced. I tried to educate my employer on certain issues, but that was a no win scenario. Many times they expected the tech to just dig up a UG bad cable line when in fact you have to get a underground utility locate first before digging and quite possibly exposing or damaging other lines such as power which is legally supposed to be way deeper than cable but many times I discovered was not.
I also trained as a utility locator after leaving ATT for awhile and then coming back under Comcast. Once again I tried to warn and educate my employer that there are laws governing what we can or cannot not do in a given situation such as underground cable damage repair, but they just pushed the techs to risk their lives anyways.
However once word got out because I informed my coworkers of reasons why I was saying no to the company many techs woke up and realized just how dangerous the situation was and many started to quote laws and code as a result.
Obviously I stirred up some trouble but I really didn't care. My coworkers safety came first and company profit last. Many customers sided with the techs once they realized how dangerous and foolish and greedy this was. It's not as if being a broadband tech really makes you wealthy. Many companies have frozen rapid advancement and many are stuck doing what they've been doing for years.
Of course many leave and go to the phone companies to be paid more and have union protections. I'm glad I don't work for one of the most hated companies in America anymore, but I certainly feel for my former coworkers who are stuck doing the same thing day in and out with no opportunity for advancement, no real respect or recognition by their employer and way too much pressure and stress and then danger to top it off.
Things would be so much better if Comcast was an employee owned company with technicians making decisions and not over greedy sales motivated bean counters who care nothing for their techs out risking their lives. For one to try and determine what the best [upstream power] levels are for their cable modem using a service such as this, its rather moot. Comcast says , another provider says , another one would say, , and so on and so on.
The reason is, no company including different markets within the same company i. Comcast Denver and Comcast Chicago is identical. The actual "sweet spot" for a cable modem to best work at is what we call "The X-Level", and it is system specific. Now someone will say, well if you said a modem can run at 60, why is it when I get to 56 I drop offline.
Because, 56 won't work in your plant. Older optical nodes, older optical transport, etc. Also, if your modem is out of "company" specifications. They already know. Almost every provider has some sort of monitoring in place. The last three, monitor every aspect of their plant.
If a modem is out of spec, you're on the watch list. Also, some of the big guys, have gotten extremely anal retentive on watching levels. Comcast for instance, at this time, their automated system will not let the technician close and complete a job, if anything is out of spec. Most cable modems are incapable of transmitting higher than 51 dBmV upstream power. They all have a maximum upstream power of 51 dBmV.
If you need to boost your upstream power and your cable provider can't resolve the issue besides suggesting you rewire your house , I highly recommend this return amplifier sold on Amazon: Electroline ERA Reverse Path Amplifier. Are you just shilling for that Amazon item?
