Ethernet and Wifi not working on opencore MacOS Catalina installer

Hello,

currently I am installing macOS Catalina on my laptop, using opencore.
I got to the point where I booted the installer successfully and got my keyboard and Touchpad running.

(Hardware specs further down.)

In order to install MacOS Catalina I need a working internet connection, but I cannot use my ethernet nor WIFI. I tried to install with a ethernet cable connection, but it did not work. I only get the message "you need a active internet connection to install MacOS Catalina".

When taking a look at the network options there is only my ethernet device with an deactivated connection status.

​

​

The WIFI Button's light on my keyboard is red and shows that the wifi is deactivated. Using the button did not switch the light and did not work. Also in the network options there is only the shown ethernet device, not the wifi card.

About the used kext files for the ethernet and wifi card I have used intelsnowmausi and tried intelmausi too.

I hope someone can help me with my problem!

Do I have to build the intelmausi.kext on my own? I just used the kext from the release version.
