I decided to get my feet wet and attempted to upgrade from 13.37 to 14. It rebooted fine
.
When I installed 13.37, I had some issues but I managed to fix. I blacklisted rt2800{sta, pci, lib} and rt2860sta. Then I symlinked rt3090.bin to rt2860.bin and it was working.
Now, modprobe rt3090 or rt2860 returns FATAL module not found.
I could probably try complete install from 14 and see what happens but I would really like to fix this problem, say for a learning point of view.
Any hint?
