Brand new build, I did not have the network drivers installed (MSI has newer chipset 10G Ethernet) so not detected. Microsoft makes it impossible to install 11 unless you have a network connection. Shift F10 & delete requirement in the control panel did not work because it would go to retry. I was able to get into the control panel and add the drivers, but it was a pain. It's been so long since I had to do something like that, and about 5 years since I built my last computer.
I think it is insane the make it impossible to install without a wireless connection.
Upgrading, completely different animal.
