How to install RTL8111 network card driver on 19.04

I tried to install and download
https://downloads.openwrt.org/snapshots/targets/x86/64/openwrt-x86-64-generic-ext4-combined-efi.img.gz
Very smoothly, after the installation is successful, the network card driver can be identified,
But the version here is unstable and has bugs,
So I installed it back
https://downloads.openwrt.org/releases/19.07.4/targets/x86/64/openwrt-19.07.4-x86-64-combined-ext4.img.gz
But the problem appeared,
ifconfig -a
Can't find the network card,
Only one local,
I don't know how to install the network card driver, can someone tell me?

kmod-r8169 should be preinstalled. Kernel policy is that there is only one driver per device, so there are no alternative, 'better', drivers - if you're experiencing bugs, they need to be fixed (depending on your exact model, a semi-optional firmeware under /lib/firmware/rtl_nic/ might help though).

How to solve it specifically, I tried to copy the rtl_nic in https://downloads.openwrt.org/snapshots/targets/x86/64/openwrt-x86-64-generic-ext4-combined-efi.img.gz
to
https: //downloads.openwrt.org/releases/19.07.4/targets/x86/64/openwrt-19.07.4-x86-64-combined-ext4.img.gz
Still not working.
