I lost my Ethernet connection and cant get it back.This was not an upgrade. In previous versions of Ubuntu this happened every time a patch was sent out changing the 8168 to 8169. Now in 22.04.5 something is different and the same fixes don't seem to work. On top of that I think I applied a fix by mistake that was for a wifi card that isn't in my system. My RTL8111/8168/8411 doesn't seem to be correctly configured. In the Advanced Network Manager under the Ethernet tab no device is listed. When I run the command
sudo lshw -C network *-network UNCLAIMED description: Ethernet controller product: RTL8111/8168/8411 PCI Express Gigabit Ethernet Controller vendor: Realtek Semiconductor Co., Ltd. physical id: 0 bus info: pci@0000:03:00.0 version: 03 width: 64 bits clock: 33MHz capabilities: pm msi pciexpress msix vpd bus_master cap_list configuration: latency=0 resources: ioport:ce00(size=256) memory:fdfff000-fdffffff memory:fdff8000-fdffbfff memory:fd600000-fd61ffff$ lspci -knn | grep Eth -A303:00.0 Ethernet controller [0200]: Realtek Semiconductor Co., Ltd.

How do I get the Ethernet claimed and recognized by the network manager?
