[SOLVED] Broadcom BCM57780 Ethernet not working on live disk

I try to install garuda lxqt on a laptop
Laptop is connected via ethernet
On this pc there is à debian ubuntu and internet works well on it.
But during garuda installation i Have a warning message "no connection to internet"
I am New to garuda and couldn't setup correctly my connection. Didn't find how to connect to my box.
Any advice is welcome.

Also, you can install without an internet connection if necessary and fix your issue afterwards.


Try wireless connection.

USB Android phone tethering is another option for a temporary internet connection.


i tried modprobe commands but didn't work. I decided to make the installation without internet and it worked! Internet worked at first boot .
I discover garuda and i am very impressed. I hope it won't be too complicated to switch to arch from debian. Thanks for all your advices.
