new motherboard, ethernet not working

Lucien_Lachance

luckily i had a ethernet usb dongle that works

yes i know, realtek ethernet sucks but it was this motherboard that was my option this time around.

how do i figure out exactly what realtek device i have, and how to make it work?
mobo is asus TUF GAMING B850M-PLUS WIFI

inxi -b should be able to tell it, no?

❯ inxi -b | grep Realtek                                                                                                                                                 
  Device-1: Realtek RTL8111/8168/8211/8411 PCI Express Gigabit Ethernet                                                                                                  
  Device-2: Realtek RTL8188EUS 802.11n Wireless Network Adapter

thanks

Device-1: Realtek RTL8125 2.5GbE driver: N/A
cant find anything related to that in the repos?

According to this reddit post, the correct driver should already be in the kernel. Not sure why it isn't working for you. When in doubt reboot?

You might also try downloading (transfer to the offending computer via USB stick or something) and installing the driver manually, but you'll have to reinstall after every kernel update. Seems like they had some luck in this Mint thread: https://forums.linuxmint.com/viewtopic.php?t=357102

ive decided to get a better usb dongle, so that ill never have this problem again
did the same with audio a few years ago, the soundblaster usb audio card is excellent
