Any docs to this effect? I'm curious to check them out because I've had flawless wifi under GNOME across various work laptops since at least 2010. Maybe it's Ubuntu+GNOME specific, haven't run Ubuntu, but it certainly doesn't seem to be GNOME.
Ah, on re-read of the OP comment, it's "wifi issues and freezing", two different problems they had. Have never seen either from GNOME though.
