Ethernet Connection Win11 Laptop to existing Workgroup

ASUS TUF (A15) 506C notebook does not connect to existing workgroup via ethernet connection.
The wifi connection is working. However, I want to use an ethernet connection so the refresh times are faster when I have several large CAD files open.
With direct connection to router, router shows link lamp illuminated green.
Running ComandPrompt > IPConfig, the ethernet address appears to be some default value 169.254.101.243 with a Subnet mask value, but no Gateway value (blank). Booting the laptop with the ethernet connection present does not yield any different a situation. Sadly, I am a legacy Win7/8/10 person. Finding stuff in Win 11 seems to be a cat-and-mouse puzzle (thanks Microsoft IMHO).

Are there any how-to tutorials available for getting into the Win11 configuration of the ethernet settings and establishing a connection to an existing workgroup ? I'd really like to be able to work faster then the wait times I am experiencing with 'saves' and 'file updates' over wifi.

Thank you everyone in advance - for any feedback and/or links to tutorials in the Eleven Forum.

Windows 11 is more like a major feature pack for Windows 10 (even 8 or 7). You have the new GUI on top of the old. Thus, you can still access the Windows 7 GUI. Quite easy to find/access too. Just you the Windows Search function - and search for "Network" which will give show "View Network Connections" Click on it - and from here on you have the old Windows 7 - > 10 GUI. 1st things first - Ethernet should be displayed as enabled (if it's not, there's either a driver, cable or hardware issue). Accessing it will let you configure your own settings (like TCP/IPv4 for IP and Gateway).

If you check the address bar - you'll have: Control Panel\Network and Internet\Network Connections Clicking on Network and Internet - will let you access the other network settings (the old school way - to put it like that).

For a quicker access to those settings (and changes on the go) - you could use an app like NetSetMan

NetSetMan - Your Network Settings Manager

The Free version covers most needs of a home user - except for Network-Domain (more common in a work/professional environment) & Proxy

When your PC network configures as 169.254.101.243, it doesn't have an assigned IP address.

It sounds like your Wi-Fi network has working DHCP, from the Wi-Fi hub or as part of your local network. This provides a working IP address & gateway whenever online.

Your LAN connection doesn't appear to have DHCP. Ask your network or IT person. It might be they don't use DHCP on ethernet, and just provide fixed IP addresses to new PC's.
