Windows 10: New Windows 11 Professional PC not recognized by router with wired ethernet connection?

Recently, I replaced a down workstation with a new machine that uses Windows 11 Professional, the old system used Windows 10 Home and had no issues with being detected by my network and internet devices. Our setup consists of a cable modem and a standalone router. The older machine was detected without issue as a Wired connection type as well as the PC Credentials for the purpose of device management and port forwarding. This new machine only shows up if I use a Wifi adapter and even then, it won't show in the router tab, it only shows when I choose the show all option on the router web ui.

Why can't Windows 11 identify the ethernet connection to the router?

Trying to perform Windows 11 clean install on new built pc. The OS was previously installed on an NVMe and was accessing the internet using an ethernet connection. Had to correct a problem and decided to remove the Home version and clean install the Pro version. During the installation, the OS wants to make a network connection. It doesn't recognize the existing connection to the router. I'm using an ethernet cable. The router functions. I have another computer and printer connected and all are working. My phone also on the network. The board is Asus ROG Maximus Z790 Hero. There's 32 GB and DDR SDRAM on board. Downloaded Windows 11 Pro from Microsoft and am using a bootable USB-C as the install device. Used Create Windows Installation Media to make USB-C bootable.

 

Using a router to connect PC with Ethernet

Their is only one phone jack where a modem can be placed in our house and it is to complicated to get Ethernet from the modem up to my computer. I can still connect with wireless internet but I want to be able to use Ethernet. The modem is a all in one (router+modem). If I buy a router and place it in my room can it connect to the all in one modem without using a phone jack (Just plugging it into the power outlet) alowing me to connect the router to the PC using Ethernet?

I installed a new wireless **** Surfboard today for internet connection. My windows 10 was previously hooked up to a ethernet cable that was attached to wireless repeater. I disconnected the ethernet i restarted the computer. The computer will not
recognize a wireless connection. I have reviewed several suggestions on trying to remind the wireless option but to no avail. How do I get the computer to recognize the new router/modem.
