Question WiFi download speed stutters on computer (video provided) ?

May 10, 2021
I've been having wifi problems on my computer, the connection used to work perfectly fine, until one day, presumably after a windows 10 update, the wifi ping and download speed started to become unstable on my computer, note that i say on my computer because it works perfectly fine on every other device, please refrain from recommending me to try connecting with an ethernet cable as it isn't a possibility.

Things i've tried:

  • switching from 2.4ghz to 5ghz with different network adapters to no avail
  • buying a newer, better network adapter with no results (except higher download speeds when it does reach its maximum potential for a few seconds)
  • reset winsock and reset through win 10's network settings
  • call my isp, who found no problem in the connection
  • go back to the previous windows 10 update
  • go back to the newer update
  • uninstall and reinstall/update network adapter drivers
the connection is completely unstable at least on my pc, it is so bad that i have to tether from my phone 4g to get 100 ping on WoW and make it playable, if anyone knows how to fix this stuff please help, also note that it did work fine for a whole week prior to now.
