PC/laptop working and processing so much harder on low quality data connection

[abdulbadii]

Why PC, mainly laptop, wifi is working and processing so much harder and more heavily when the internet data it receives is at low speed and/or intermittent, as opposed and not due to weak wifi signal strength i.e. its low dB.

What actually is whichever processor(s) is/are working and/or searching on, and what actually has triggered it/them to obligatorily working and processing in such the mentioned conditioned ?
How  do we mitigate or solve this (mainly my) problem ?

I'm not sure what you mean by this? This is something I haven't noticed on any machine, ever...

Typically higher data rates require more processing power to cope with the data rate, not the other way around.

My old Lenovo Carbon X1 2015 showed me something similar under Windows 10.
I sold the laptop, and bought an Apple M1, I have never verified with Linux and It's too late now

Sounds like a driver issue more than anything. I mean I'm not a programmer, but in my real-world experience, low bit rates over a normally fast interface does not equate to increased system load.

Yup, precisely what I mean: probably we are talking about bugs and/or defects with the OS.

I didn't have the time to check for a WiFi driver alternative, I received the laptop already installed and I simply used it as-is.

Now I am reverse engineering a USB device that only runs on Windows XP, and I see there are stupid running programs with fancy names that monitors the WiFi and increase the system load for silly reasons.

Again, I don't have the time to investigate so ... as a workaround I'm using a wired connection and the problem has magically vanished.

This, or ... it's just that the Wifi hates me, dunno
