What Is Noise?

What is noise?

Can it affect Linux/*buntu?

How might one limit or eliminate the effects of this “noise” in both Lubuntu and at the router?

I had a customer with Internet issues changed the modem 3 times kept having the same issue. Come to find out it was noise because of the mainline cable down the road.

Hi Mate

“Noise” is typically only seen on copper lines, and occurs when external (often electromagnetic) interference affects the data being sent https://www.promptlink.com/media-library/blog/what-is-broadband-network-noise-and-why-is-it-difficult-to-find.html. This is a physical (Layer 1) problem, and no OS (including Ubuntu and its variants), nor choice of modem, can stop this from occurring.

Noise can be more complicated than this, but, given the limited information provided, it sounds like an ISP issue downstream from the endpoint, which is beyond the control of end users.

Do you have a problem you are trying to fix?

Or just wondering?

I went to Google to do a sanity check on what my past career exposed me to, regarding possible solutions for filtering out noise.

The noise can originate from

  • High-Voltage Power Transmission lines
  • Power-Line Arcing
  • any businesses in your vicinity using switch-activated solenoid coils for Punch Press work, Injection-Moulding presses, Assembly-Line robotics, residential or underground static from power-line shorting, etc.

If you enter the following strings in a Google search, the response will confirm that some brands of UPS (uninteruptible power supply) do have built-in capability to filter out noise from an internet connection plugged into an RJ-45 jack in the UPS unit.

UPS "power filtering" "internet noise"

One example of such a product is the following:

You would have to check with each manufacturer to get specifics on the degree to which they can filter power static noise from the network communication lines.

Interesting topic, by the way.

And copper lines is what is running through my walls from the connection outside to the router inside.
Land owner won’t allow changes within the walls.

And ISP won’t allow changes within “their” router.

Completely locked me out from making changes.

An ISP representative came and asked if we would like to switch ISP.
So I let him see a speed test with my current ISP.

turns out it was 50mb/s for ~$100.

Competition was 500mb/s for half that price Intro 3 yrs.

I never exceeded 60gb daily data usage.
So I took the 1 month free option.

I powered off the previous ISP router.
Three days later I checked the data usage with that ISP.

I still had small daily data usage for those three days.

Switching ISP, if remaining on copper, * might * not make a difference. Even going Wireless does not offer guarantees.

IMHO, only sure way to get away from (filtered to truly negligeable measurement) transmission static, is to adopt an ISP which provides access via optical fibre.

I can only agree, but also adding the fact the ISP don’t need to be so paranoid that they try “proving” only those who “work” for them are “smart” enough to “service” their router settings.

You seem to be suggesting that the router would have a built-in capability to manage/tweak/limit that noise. I honestly believe that your expectations are not well-founded.

isnt a router automatically set to “channel 11” if I remember correctly on the “broadband”.

The very channel that 99.9% of users are using?

When that router was installed by the ISP, I asked them about that and they said they dont want me in there “messing” with it.

I got locked out of “reconfiguring” those settings.

I know for sure…I tried logging into the router settings just last week.

Yet, everywhere I look, I see guidance about going in and setting a static IP and setting to different broadband channels, etc.

Of course all it takes is one person to mess things up for everybody else.

This most likely came from somebody not doing the research before making changes.

They really are “paranoid” against those who don’t work for them.

Now…those workers get their “apps” at either a discount or paid for.

They said for me to use AVG Anti-virus and Malwarebytes. The set-up they were talking about turned out to be the paid versions of those “Windows Apps”. That was 4 or 5 years ago.

I was under the initial impression that you were “wired”.

Can you share the specifics of the Wireless router (Make and Model) that you seem to indicate that you are using?

Do you currently have login access to your router modem?

On you router modem, do you see anything on the backplate that indicates the “Factory Default” ID+Password for login?

Is there a “pinhole” where you can insert a pin to perform a hardware “Factory Reset”, that would then let you use that above-mentionned default ID+Password, and you could then set your own Admin password for ongoing access?

Thank you for that info.

I’m in the process of switching ISP.

In my area, I’m one of a group of at least 100+ users who are switching away from that particular ISP for this very reason. Not to mention they’re increasing their price’s for some reason (price gouging).

Some of us believe it’s because of unwanted and unexpected political outcome’s due to the “We The People” standard’s.
