"M1 Mini/Big Sur - All Networking stops: I've had an ongoing issue with my Mini for a few months now and recently its got worse, now happens about once every 24 hrs. Basically the machine is running fine other than it has no network connectivity, normally both WiFi and ethernet are connected but this will just stop browser won't open any pages, slack is disconnected and I can't even ping the router.[...]"

Troubleshooting Mac Wi-Fi:
A few thoughts to try
I. Clear the Temporary Internet Files:
II. Restart your Router:
- Power: off the router
- Wait: 30 seconds
- Power: It back on
III. Boot in Safe Mode:
[Hold Down: shift key, upon boot], In Safe Mode, Login Items do not run at login, certain preferences are set aside, and damaged system files are then reset. So, once booted in to Safe Mode, wait 30 seconds, and then boot up normally, attempting another update install.
IV. Try a New Admin User:
What happens when you create a new administrator user, and log into it? Do you still get this error? If not, then it is likely an error with the current user. If so, then it is likely an error with your Mac.
V. Reset your SMC and your NVRAM:
Sometimes changes (i.e. Installations) are made to the system and then settings (i.e. Networking) become corrupted, technically. So, reset both on your Mac. So, reset the SMC and reset the NVRAM or PRAM. It might take three tries. to fix this. So, be certain you have the time to do so.
