I keep losing my WiFi adapter

I tried the Option 2 approach but kept getting the Error NetSetupDeleteObjecton Network Adapter error (0x80070005) error, even after a dozen executions of the command. That seemed like it was going nowhere so I tried Option 1. After completing the reboot in Option 1, I never got the dialog that asked if I wanted to make the computer discoverable, even after a significant wait. Do you have any further suggestions? I'm going to move on to "Compumind's" suggestion in the meantime and see if that helps.... - - - Updated - - -

I started working my way down the list.

1. Both the ipv4 and ipv6 resets said "access denied!". However, the mere attempt worked *briefly*, then the WiFi went down again.
2. I disabled and re-enabled the network adapter. Again, it worked *briefly*, then I lost the WiFi again.
3. I tried to disable the antivirus but couldn't find a setting for that so uninstalled it entirely. I got the WiFi back and this time it stayed on for several hours instead of a few minutes so I assumed it was fixed. Then I installed the new Avast One and the WiFi is still working so I'm assuming that all is well finally!

Thank you for this list of suggestions!!!
