You should not need any DKMS packages nor an OEM kernel. The stock Ubuntu kernel supports your NIC natively. Remove the DKMS modules and reboot into the 5.19 kernel and post the dmesg output from that boot.
lsmod should list the r8169 module. And: $ modinfo r8169 | grep 8125 firmware: rtl_nic/rtl8125b-2.fw firmware: rtl_nic/rtl8125a-3.fw alias: pci:v000010ECd00008125sv*sd*bc*sc*i* And the firmware should be there as well: $ ls -la /lib/firmware/rtl_nic/rtl8125* -rw-r--r-- 1 root root 3456 Apr 21 07:41 /lib/firmware/rtl_nic/rtl8125a-3.fw -rw-r--r-- 1 root root 10128 Apr 21 07:41 /lib/firmware/rtl_nic/rtl8125b-1.fw -rw-r--r-- 1 root root 3328 Apr 21 07:41 /lib/firmware/rtl_nic/rtl8125b-2.fw -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux-firmware in Ubuntu. https://bugs.launchpad.net/bugs/2022826 Title: Ethernet hangs Status in linux-firmware package in Ubuntu: New Bug description: I'm now getting my wired (i.e. Ethernet) connection hanging on trying to connect. I've tried switching ports (on the router) and using a different cable, but still the same. ifconfig shows for Ethernet: enp2s0: flags=4163<UP,BROADCAST,RUNNING,MULTICAST> mtu 1500 ether 50:eb:f6:ef:a4:e6 txqueuelen 1000 (Ethernet) RX packets 2779 bytes 250524 (250.5 KB) RX errors 0 dropped 1 overruns 0 frame 0 TX packets 355 bytes 72171 (72.1 KB) TX errors 0 dropped 0 overruns 0 carrier 0 collisions 0 sudo lshw -C enp2s0 shows nothing lspci -nn shows for Ethernet: 02:00.0 Ethernet controller [0200]: Realtek Semiconductor Co., Ltd. RTL8125 2.5GbE Controller [10ec:8125] (rev 05) I found a web page: https://tutorialforlinux.com/2021/05...based-systems/ I followed the instructions and installed realtek-r8125-dkms package OK. On rebooting, I followed the instructed procedure (shown when installing the package) of creating a password and then entering it when requested on the reboot. But still same problem. Any ideas what to do? PS I've switched Wi-Fi on (though I'd prefer to use Ethernet, as my Wi-Fi is a little flaky due to walls) in order to post this question.
