Windows 10: "Default Gateway Not Available" Network Problem

I need help fixing a network error on Windows 11. After running a diagnosis, the result was "Default gateway is not available". I have researched the problem and have performed many, many different methods to repair this, but the error is not resolving. Any suggestions to fix this error?

Default Gateway Not Available Problem

I recently began getting the default gateway issue. It connects if I reset but, keeps coming back.
I have tied a few of the popular internet fixes to no avail. Checked for updates, changed power management options, etc.
It has been suggested to uninstall/reinstall the driver but, I am not sure what driver is what.
I have listed under network adapters in the device manager:
Broadcom 802.11n Network Adapter
Intel(R) 82579 LM Gigabit Network Adapter
Which of these is actually the wireless adapter?
I have read lots of posts about this but, no real answers.
Using Google Fiber. I am fairly sure that the issue is not with the router as I have another laptop with Windows 7
(the one I am using now) and it does not have this problem
I am not much of a computer person at all so, please boil it down to dummy level for me if you choose to respond,

 

Default Gateway not available

The "default gateway not available error" occurs frequently when connected to my ISP's modem. This causes the internet connection to drop frequently and I have to run the troubleshooter to restore connection. I have gone through
all of the steps in the article

The problem persists.
