Hang on connect to router for Ubuntu 22.04 for Realtek8125 ethernet. I have downloaded ‘r8125 installation file’ from entry 2.5G Ethernet LINUX driver r8125 for kernel up to 5.19 on Realtek’s webpage (https://www.realtek.com/en/component/zoo/category/network-interface-controllers-10-100-1000m-gigabit-ethernet-pci-express-software). But it gave ‘System Map’ warning and modprobe fail. Here is the log:
john@Desktop:~/Software/Realtek/r8125-9.011.01$ sudo ./autorun.sh
