Bonjour à tous,
I have a problem with my wifi connection which is annoying.
Material: MacBook pro (15 inches, 2019) macOS Big Sur (but the problem is present since a while, not related to the version)
From time to time, when there is a small download spike (I open a new web page, I open a youtube video...), the connection suddenly stops and comes back after 5-30secondes. Typical example bellow:

The solution that I found was described in a previous post (here: Network connection timeouts on MacBook Pro). The solution was to remove files from the systemconfiguration (Library/Preferences/SystemConfiguration/):
- com.apple.airport.preferences.plist - com.apple.airport.preferences.plist-new - com.apple.network.identification.plist - NetworkInterfaces.plist - preferences.plist
But this is a temporary solution because the problem comes back and back... it becomes unbearable.
Before removing the files (during a download, you can see that the connection is completely frozen suddenly and comes back):
After deleting files from Library/Preferences/SystemConfiguration/ ((during the same download):
So it works well on the moment, but the problem starts to appear again after 1h-1day. Apple or a program does something but I don't know what.This problem only occurs with my home connection. This problem did not appear at the beginning but about 6 months ago (I live in my new house since one year)
I don't have a problem anywhere else. You might think it's from the wifi but I only have this problem with this Mac.
So I don't know what to do except to erase and restart; but I think by using my time machine the problem will appear again.
So if anyone has an idea of what I can do (because I'm running out of ideas now), I would be very grateful
Thanks in advance for your time and your answers :)
