I'm at work now so hard to do much... But I was able to remote in with Teamviewer through my phone and look at some settings.
Went to Network Connections > Edit (on my wifi connection), then went to IPv4 Settings.
Method is set to "Automatic(DHCP)".
For IPv6, also set to "Automatic"
The windows machine is also setup to use DHCP automatically.
I will be able to look into this more easily when I get home from work.
Thanks for the welcome, I may be finally posting some questions here since having a dormant account for years
