My new Macbook Air M3 loses wifi connection.

It's been 12 hours of migration/installation on this new MacBook Air M3 that I'm doing and I notice that the internet connection gets lost occasionally (10 minutes). I also have an iMac 2020 and a MacBook Air M1 2022, which work fine on the same network and on the same table for testing. I've restarted the router and the computer. I even validated the Dropbox settings. I read on the forum that several people seemed to have the same problem but no solution. I ran the wifi diagnostics and it noted that the connection was interrupted, but no solution.

The purpose of buying this new Macbook is to work on the road, so always on wifi.

I'm told to turn the computer upside down before doing this, anyone have any ideas?
