@iCanaro  Well, as 1.0.0d6 and 1.0.0 are virtually identical and differ only in the version number, it's not the driver but a link error which is responsible for the kernel panic. Please see post #1 for a guide how to get rid of it.

 

@ITzTravelInTime As Mausi and Carlos both died in 2014, Lucy is my only one cat at the moment.

 

I ordered my RTL8125 directly from China via Aliexpress as this was the cheapest solution (approximately 20€) last fall but you may choose any RTL8125 based NIC.

@vuongdingo Actually I don't understand your problem? Connection speed is determined by auto-negotiation by default but in case this doesn't result in a valid connection, use System Preferences or ifconfig in Terminal to select the medium manually.

I enter this command ```ifconfig en0 media 1000baseT```

But

The problem here is I can't connect to internet in install step, it required to internet.

The installer also has Terminal (among other utilities) available and you can select the medium before starting the installation.

An internet connection is required to install MacOS Catalina; 3700X, RX 5500XT, MSI x570 tomahawk wifi with Realtek® 8125B 2.5G LAN controller

I have the same issue. I am installing MacOS Catalina by OpenCore version 0.6.1 with following configuration:

·         Ryzen 7 3700X,

·         Sapphire Nitro RX 5500XT,

·         MSI x570 tomahawk wifi with Realtek® 8125B 2.5G LAN controller

I have gathered all required files and doable with LucyRTL8125Ethernet.kext[V1.0.0d6] according to installation guide. But when I am going to install Catalina, a message “An internet connection is required to install MacOS” is showing. Please guide me to resolve the issue.

Well, in this case the problem is located somewhere else. Please fix your system!

If I chose Network -> Advanced -> hardware and set 100baseT, Ethernet will work. If I chose another doesn;t work. How can I using 1000base or 2500base?

Studying lastest Linux driver sources I found out that problems with 1000MBit connections on the RTL8125B might be related to firmware issues. In order to resolve the issue a driver update is required but I won't find time for it before March because I have to study for an exam I'm going to take on March, the 4th.

Give me one good reason why the driver might need an update for Big Sur!

@Mieze - you make me want to create a kext so I can name it after our cat.  The kids named her Moosh Moosh before they could actually talk.  Do you think people will want a kext named MooshMoosh? :)  Thanks for everything you do.  A few of my old hacks are still alive and kicking with your kexts.
