"Only restart will temporarily restart the wifi: My mini Mac M2 stops getting internet via cable and getting WiFi also after a short time after restart - all other devices have Wifi just fine. What must be done to correct this malady? I am using Golden Gate 27 but this occurred in the previous OS MY videos just quit - speed test says there is not connection - there is a connection as all other house hold devices work fine"

Losing Network Connectivity:
A. Remove Login Items:
See if there are any Login Items that are installed. If so, remove them, as they may be pending something.
Go Here: Remove Login Items to Resolve Startup Problems on your Mac - Apple Support
B. Remove All Networks:
Remove your networks, and add them back. IMPORTANT: If you have any passwords, then make sure you keep a copy of it so that you can get back into the network, later.
- Go Here: Use Network Locations on Mac - Apple Support
- Scroll to: Add or remove a network location
- Proceed from there as necessary.
C. Remove ALL VPNs:
Do you have any VPNs installed? If so, remove them; or, just turn them off, if required for school or work.
D. Single-Out this User:
For troubleshooting purposes, create a Time Machine Backup of your Mac, and then create an Administrator, seeing if you get this issue. If not, then it is an issue pertaining to your current user. If so, then it is an issue with the entire macOS. Then, trash this user, if no-longer needed.
