Task Manager shows no speed although a file is being downloaded.

When a file is being downloaded, my Task Manager shows no speed in the "Network" column as shown below:





Have you seen the same thing on your Task Manager?

Indeed, do not worry about those numbers or indeed graphs and bar displays. It is a combination of sampling frequency and the precision and/or rounding of numbers.

A simple demo is if you change the sampling frequency in the Task Manager.
Go to Performance and select Ethernet, then View Tab > Update speed(sample rate). By default that is "Normal".
Changing that will result in quite a difference in the displayed graph.

Also the numbers displayed in the left panel are probably only 8 bit for reasons of speed using less resources than if 16 or 32 bit precision was used.

I see the same if using Cloudflare Warp. Everything shows "zero"

Warp does not exist on my Windows and Linux. Everything shows "zero" on both Windows and Linux.
The problem possibly lies in my hardware.

I don't worry about anything. I am just interested to know whether it is a hardware or software problem.

I read that it's a driver issue or having more than one app installed that can monitor network activity.

I have no app that can monitor the network activity of any given process. "Zero" is displayed in any case on any OS.

It is not a "problem" in hardware or software.

You will have to read up on how numbers are held digitally and how sampling rates of data matter in respect of accuracy of display, balanced with resource usage.
Obviously a 64 bit precision number held in RAM or any sort of memory will take up more room which is hardware related, shuffling around the number takes more time and resources and so on.

That is where software designers come into things, balancing these factors out.

Even 50 years ago with analogue meters factors had to be taken in to account like viewing angle/thickness of a needle above a scale and the current the meter itself would take.
