I would be guessing too much here. Try adding a Web Speccy so everyone can see what's under the hood so to speak. How is at https://www.piriform.com/docs/speccy/using-speccy/publishing-a-speccy-profile-to-the-web
In the meantime be sure this next setting is turned off. Read how at https://www.howtogeek.com/224981/how-to-stop-windows-10-from-uploading-updates-to-other-pcs-over-the-internet/
That setting could cause odd WiFi slowdowns.
So far, no one has been able to help me with this and in the forums I try no one will even answer. I’ve run it by both professionals and laypeople and they either say it’s impossible or they don’t believe me, or, like the management at my apartment building, try to blame it on something wrong with my laptop(s). Here is the best description of the problem I can give you: When I'm at home, and only at home (an apartment building that provides wifi with 4-5 "points" to choose from), my wifi is dramatically slower than it is anywhere else (McDonald's, Starbucks, the library). I can never get through a short film on a short film site I like to use; I cannot stream radio audio without it being interrupted; Google Chrome locks up; and sometimes I cannot get through a Netflix movie - AND - the strangest thing (to me) - is that when it is at its slowest, my ENTIRE LAPTOP slows down, and "breathes hard" (for lack of a better term) - the fan vent lets out thee long "exhale" sounds like it's exhausted - Word and other programs slow down. If I disconnect from the internet everything goes back to normal. I have two laptops and a Kindle and all three act the same way when connected to the wifi at home - are fine everywhere else. Is there anything I can try on my end (settings? blocks? ect?) Moving is not an option. Thank you.
