I am having the same issue as the rest here. I have tried everything on this thread with nothing working.
The ONLY that came close to working was using a USB wifi adapter which worked to the point of signing in to the network. I signed in and click next and it said I am not connected and to go back. So, I go back and it says that I AM connected to the network, click next and it says I am not connected.
I have the updated drivers for my motherboard - MSI MAG Z790 Tomahawk - but can't get out of Win setup to try and install them. Is there supposed to be somewhere in bios where I can update the wifi and network drivers?
I also tried connecting with a ethernet cable and that didn't do anything.
Any other suggestions?
