PC working/processing so much harder on low data connection, know solve?

Question

Why PC's mainly laptop's, wifi is working and processing so much harder and much more heavily when the internet data it receives is at low speed (40 kbps max) and/or intermittent, as opposed and not due, to weak wifi signal strength i.e. its low dB. This's outright conspicuous when performing a media streamingWhat actually is which processor(s) is/are working and/or searching on, and what actually has triggered it/them to obligatorily working and processing in such very hard which leads to real problem: quickly gets overheating?How do we mitigate or solve this (mainly my) problem ?

Speculation, but are you sure it isn't the other way around, and something is chewing up your CPU time, which is then turning into the bottleneck. If you did profiling to actually determine where the CPU time was being spent, then you would probably be able to make a more educated guess.
