I have 14 rigs working perfectly, but my 3 new ones will not connect to internet on both cable amd wifi. The 3 boards that does not work is 2 b850 and one x870 boards. They work fine with windows.
What am I doing wrong?
those chipsets are newer than the latest build supports out of the box, there are a few options:
-generic usb ethernet adapter for ~$5
-manually update kernel/drivers, though you will need an internet connection, so either run the install on an older system, update everything (install newer kernel, install necessary drivers), then transfer boot drive to new system, or temporarily use a usb ethernet adapter to do the install.
imo usb ethernet are a good thing to have laying around to troubleshoot with so id recommend getting at least one to use here
