I just got a MSI MPG B550 Gaming Carbon WiFi motherboard. I installed Ubuntu 20.04. When it booted to the OS it will only see wifi and no ethernet connection. Do I need to get drivers in order to get this to work? Seem odd that the wifi worked out of the box, but no ethernet.

Thanks

Since your motherboard does in fact have an Ethernet port, I think it is a driver issue.

This site may help:

no WiFi and Ethernet connection on msi gaming edge wifi. Where and how do I install the drivers if possible

and so might these:

However,on the MSI website there do not seem to be any driver downloads for Linux. The links above may be your best bet, and may provide the best help for your query and issue.

I hope this helps!

Here seems to have solved it with the mystery for the driver location not stated. A search on that model lead to the third link.

Had the same issue with my MSI B550 Gaming edge WiFi board and Ubuntu 20.04.

Running lshw gave me:

sudo lshw -C network
*-network UNCLAIMED
   description: Ethernet controller
   product: RTL8125 2.5GbE Controller
   vendor: Realtek Semiconductor Co., Ltd.

Steps to fix the issue:

Download the 2.5G Ethernet Linux Driver r8125 from here.

Unpack the tarball with:

tar vjxf r8125-9.aaa.bb.tar.bz2

Change to the directory:

cd r8125-9.aaa.bb

Gave execution permissions and run autorun.sh:

chmod +x autorun.sh
sudo ./autorun.sh

In case, the previous command did not work, you can use:

sudo sh autorun.sh
