Wired Setting Missing and Ethernet Connection Not Working on Dual Boot Ubuntu 20.04 and Windows 10
I recently built a new pc and dual booted Windows 10 and Ubuntu 20.04 on them. My ethernet connection works in Windows 10 but does not work in Ubuntu. In addition, my the wired setting is missing in my network settings in Ubuntu. Any help would be greatly appreciated. I cannot seem to figure out what to do as I am new to Ubuntu/linux and have gotten lost.
I have tried to download the realtek drivers onto a usb but was unable to download them because ubuntu could not use make. I have also changed the power energy settings in Windows 10 but that did not help either. I am unsure how to proceed, I have seen people commonly provide the outputs below and I hope they help.
Here is the output of sudo lshw -C network

Thank you
I ended up fixing the problem by downloading the Realtek rtl8125 drivers from another computer and transferring to my pc via usb flash drive. After following the readme instructions in that file and running the download script the wired ethernet connection began working.
