    RTL8125 2.5GbE Controller - will not detect - network UNCLAIMED

    RTL8125 2.5GbE Controller will not show up on the network tab.

    What i have done so far.

    I have also uninstalled and reinstated Ubuntu 20.04.1 LTS. I even went back to 18.04 still same issue. I installed windows with no issues at all so i know the network adapter is working.

    I do i resolve the unclaimed network for the controller. The 2nd network is a phone hotspot using USB. My system does not have WIFI so its not other issue with WIFI realtek card.

    Thank you

    Thank you I have been able to resolve the issue. I am very new to Linux and found the drivers before on the realtec site but was not able to get it to work following the read me.

    With more research was able to determine i was missing Compiler/binutils.

    After install of those working like a champ.

    Thank you so much for all your help
