MacBook Air Won’t Stay Connected to Internet

My MacBook Air Big Sur won’t stay connected to the Internet. It never had this problem before until the past week or so. I have an iPhone with wireless service and an Android without that’s used over WiFi and they both connect to the Internet without issue. On my MacBook, for several days, if I clicked on the Renew DHCP Lease button, that seemed to work for a while, but now it doesn’t seem to help the MacBook to connect. I’m looking for guidance on how to resolve this issue.

MacBook Air 13″, macOS 11.7

Make a New Location, Using network locations in Mac OS X ...

System Preferences>Network, top of window>Locations>Edit Locations, little plus icon, give it a name.

System Preferences>Network, click on the little gear at the bottom next to the + & - icons, (unlock lock first if locked), choose Set Service Order.

The interface that connects to the Internet should be dragged to the top of the list.

Sys Prefs>Network>highlight the Interface you're using>Advanced>TCP/IP>Configure IPv4: Using DHCP.

If using Wifi, instead of joining your Network from the list, click the WiFi icon at the top, and click join other network. Fill in everything as needed.

System Preferences>Network>choose interface>Advanced>Proxies Tab, make sure none are set, like for HTTP & HTTPS.

System Preferences>Network, unlock the lock if need be, highlight the Interface you use to connect to Internet, click on the advanced button, click on the DNS tab, click on the little plus icon, then add these numbers...
